    I test drove a car with loud noise, and was told it was a wheel bearing, and would be fixed.
    Then, it was the transfer case. Now, it has been seen and fixed by Jeep specialist, what else could have been wrong with it?
    It is a full time 4wd, automatic. I am due to accept delivery, and would appreciate info.

    I have a 1994 Jeep Grand Cherokee 5.2 V8. Once you crank the engine, you have approx. 15 minutes of drive time or idle time before the engine shuts off. Then, after waiting for about 15 minutes off not touching anything, it starts back up and drives fine for 15 more minutes. I originally thought it was a fuel pump problem and replaced the pump. But the problem persisted. This time, during one of the "shut down" episodes, I checked for fire to the plug wires and "no fire". I also used starting fluid in the throttle body to make sure, it was not a fuel problem. There is not any warning signs when it shuts off. It just shuts off the motor as if using the key. When it starts back, it runs perfect. Any ideas what the problem could be. I have checked all the fluids to make sure a sensor was not shutting the engine of.

    Thanks,
    Mike...

    Just a shot in the dark, but I've heard of people having problems with the built in security system. I don't really know anything about it or what the symptoms are or even how to check it...but give it a search on this site see what it turns up. Also search google. Good luck.
  • paulepaule Member Posts: 382
    Yep, it's "aged" enough that it could easily be the compressor.
    Good luck!
  • paulepaule Member Posts: 382
    That could be a ton of things.

    I have a '98 and had to have the rear axle/wheel bearings replaced at around 100,000 miles.

    It basically was making a constant loud "hum" (for lack of a better term) that increased with increasing speed.

    It was more noticeable when the rear seats were folded down.
    Cost almost $900 at the dealer but has not reoccurred.

    That was really the only problem I had with my Jeep that I felt shouldn't have happened.

    dear paule,
    thanks for your post. It is good to hear of someone with a problem free car. I am hoping to have a trouble free ownership.

    Warranties, are tricky as they are $2800 for 3 yrs/36k. I want to take my chances, but some of these post make it sound very risky!

    Is yours a FT/4WD?

    We have a 2001 Jeep Grand Cherokee with 83,000 miles on it. Recently, we replaced the battery and the air filter. About 750 miles after we changed the air filter, the malfunction indicator light appeared. The handbook says it may be fuel or emissions related. My husband took it to the dealer and they said it has to be tested first ($75.00 minimum to diagnose) but the problem would probably cost around $200.00 to repair. Anyone else encountered this problem?

    I've recently had the water pump, thermostat and belt replaced in my 2000 Grand Cherokee Laredo. The ac unit was working just fine but now it blows whatever kind of air that's on the outside, which lately, has been very hot. There is freon in the unit. Can/will anyone help me?
    Also, on a different note, when I open the driver door, it gives a pop sound. I've sprayed WD-40, still does the same thing, other than these two things. I love my Jeep!
  • paulepaule Member Posts: 382
    My Jeep will have a different 4WD setup than your LTD. I have a 4.0L Laredo with the SelecTrac which is not full time 4WD.

    It is selectable but I do use the 4WD a fair amount. I have not had any 4WD related issues.

    Whether a warranty is worth it or not is always a gamble. I haven't even come close to putting $2800 into my Jeep in the 7 years I've owned it. It now has over 167,000 and is running strong.
  • paulepaule Member Posts: 382
    If the vehicle is still running fine, I would drive it for a couple of weeks to see if the light goes out.
    A loose gas cap can turn on the light. If that's what it is, the light will go out after several drive cycles.
    The dealer sounds a little questionable. How can they possibly know how much it will cost to fix it before even diagnosing the problem?
  • j_man_dogj_man_dog Member Posts: 1
    i had the same problem with my 2001 JGC... but not quite the same story... this problem happened to me after a day of driving on the beach and getting stuck in about 4 ft of water for about an hour or so and water coming up to the bottom of the seats.... but i left it here in the florida sun for 2 weeks while gone on vacation.. when i got back i tried to start it up.. but nothing, it just clicked once and never tried to turn over or anything. come to find out my starter had gone bad. long story short, replaced the starter/solenoid (comes as a combo for JGC) and all my problems were solved. windows worked gauges worked air worked etc etc... hope this helps some .. the starter cost was around 170. but well worth the price to fix all those problems. :D

    Hello,
    My daughter's GJC air conditioning blower motor is out. I checked the 40A blower motor fuse in the relay?/fuse box next to the battery. It ohmed out o.k. Where is the blower motor relay located? The only thing in the "box" that looked like it could be a possibility was the ASD or the TCM. One person posted a message on another GJC and said that the relay was under the battery (hopefully on an older model GJC).
    My daughter and I thank you for your advice!

  • bikermark1bikermark1 Member Posts: 1
    Hello,
    My '94 GC with Quadratrac is randomly displaying "Service 4WD Switch" on the VIC when driving on dry pavement. Does anyone know what this means? How hard it is to fix? or how much it will cost? Any input or experiences would be greatly appreciated.
    Thank You,
    Mark
  • pek1442pek1442 Member Posts: 3
    First, I'm sorry that you've had the problems with your 2005 GC. However, I would not consider buying anything other than a DiamlerChrysler product. It is very clear that there is more German engineering in all of their products as a result of probably one of the better car mergers in history. The fact that Jeep is now backed by without a doubt the worlds most prestigious auto maker means they will stand behind what they build. I have had mine since the day it came out in October 2004, I have 18,500 on the V6 Laredo. I haven't encountered any problems. It drives amazing, more like a car. You can thank that on German engineering. I just can't imagine some of the frustrations you claim to have had with DC customer service. I've had to deal with them when I had my stratus and they made sure my issues were resolved. It also isn't a wonder that GM and Ford are losing so much ground, do you hear DC in that same sentence? No because they are actually making money.

    I'm not sure if you have the same problem I had with my 1999 Grand Cherokee, but the guage rising... then pegging out suddenly was nearly identical to my experience. In our case, the problem exhibited itself when we were sitting at stop lights on hot days, and running below 40 miles an hour on a hot day with a tail wind. Turned out to be the electric fan on the radiator. I diagnosed it by turning on the A/C, which forces the fan to run even if the car isn't hot. It didn't operated, so I took it to the shop for testing. They replaced the relay for the fan, which made the fan operate at the time, but a few weeks later it stopped working again. Same problem when stopped on hot days. Was ready to take it back to the shop for a fan replacement when a mechanic friend suggested that I check to make sure that the fan motor brushes hadn't worn down and weren't making contact any more. He told me the best way to find out was to whack the motor, which would free the brushes to extend. IT WORKED. Fan worked fine for two years. Had to do it again this week, and IT WORKED again. I know the fan should be replaced, and will do it. But being trapped in traffic with an overheated Jeep is no fun. I now carry a hammer and a pipe just in case.

    I have a '99 Jeep Grand Cherokee Limited. Something is draining my battery. Now they say it is my Alarm system, so after putting a new one in $350, the battery still drained. Now they disconnected my new alarm system and say that is my problem. I don't think so. Now I have a new Alarm system that isn't even connected and have no remote to open doors, etc. Anyone have similar problem, WHAT COULD POSSIBLY BE DRAINING MY BATTERY?? Help!!!!
  • ilmm4ilmm4 Member Posts: 1
    Would I be able to take out the ABS fuse for my brakes and would they still work fine. I really don't like the way they work when I have to hit the brakes hard. Also is the fuse wired into anything else that would crap out if i took it out.
  • sideburnssideburns Member Posts: 3
    Hello, the display on the CD player for my 1995 Jeep Grand Cherokee has stopped working. Everything still plays, CD's, radio, etc., but the display is blank. Could it be a fuse? If so, could you tell me how to fix it. Also if I were to replace the CD player, what would you recommend I replace it with?
  • bobbyvee007bobbyvee007 Member Posts: 5
    I HAVE THIS HOWLING SOUND WHEN IM DRIVING ON THE HYWAY AS SOON AS I GIVE THE GAS IT GOES AWAY WHEN I LET OFF THE GAS PEDAL IT IT SOUNDS AGAIN SOUND LIKE IT COMING FROM DRIVERS SIDE FRONT
    ANY HELP ON THIS WOULD BE GREAT

    I have a 00 Jeep Grand Cherokee Limited. I was having the same problems. Sometimes at night, I would see my headlights flash on and off. Sometimes, it would stay on for awhile. I had switched my headlights from auto to manually turn my lights on. Since then, I've had no more problems with my battery. So Far!
  • paulepaule Member Posts: 382
    Not sure if this is it or not but check your exhaust manifold where the pipes join together down by the flange joint with the main exhaust pipe.
    The 4.0 L exhaust manifolds are known for cracking.
  • paulepaule Member Posts: 382
    The only true way of finding the problem is to hook up a meter and start pulling fuses until you find the draw. There are some tricks to it so you may be better off having a garage with a good electrical tech do this for you.
  • paulepaule Member Posts: 382
    Sounds like the display just went out. Odds are pretty good it would be easier to replace the CD player than to repair it. I doubt it is the fuse since the radio still works.
    Contact someone like crutchfield and see what they recommend. I put a Sony CD player in my Jeep and I've been pretty happy with it.
    If you want a particular model number, let me know and I'll dig it up.
  • paulepaule Member Posts: 382
    Boy, I really wouldn't recommend that. ABS brakes pulsate when you get on them hard but they're supposed to do that.
    "Stomp and steer" is what they say.
    Why do you want to disable them?
  • gto1970gto1970 Member Posts: 2
    I have a 97 Jeep grand cherokee limited with the 5.2 and it has climate control. When the a/c is used and floor is selected the rear pass floorboard gets filled up with water. I can see water comming out of the little vent on the floor in the pass-rear. It probably has a clogged drain somewhere. But where is the question. Can anyone help?
  • bob_grahambob_graham Member Posts: 63
    Has anyone experienced the headlights flashing for a moment while the car is off and parked. I have a 2001 JGC Limited and it just started doing this. The driver selection 1 and 2 has been working incorrectly also.

    I disconnected the battery for 4 hours and the problem seemed to go away.

    Any info would be appreciated.
  • mtelseymtelsey Member Posts: 10
    I would just like to get some feedback from someone who has the 05 jgc and has had the a/c leaking into tranny fluid... Mine is back in the shop, for the second time, and now is having the transmission rebuilt. Mechanics say chrysler won't let them put in a new tranny unless 70% or more is damaged in the old one, so if less than that, have to fix what is wrong in it. It is frustrating cuz I will now have a 2005 jeep in the year 2005 w/ a rebuilt transmission. Has anyone else gotten this far w/ this problem? If you have, can you please tell me if this has fixed the problem once and for all?...
  • nosligcnosligc Member Posts: 2
    I have been having the same or similar issue with my 1999 Grand Cherokee. In my case, I have the switch set to automatic. I have had the lights turn on automatically even after several hours of being parked. This happens anytime of the day or night. I have also had the lights flash while driving in normal daylight as well as the radio cutting off and the lights flashing when using the turn signal. I have had the jeep in for diagnostics, however, they were unable to find anything wrong and were unable to duplicate the problem. Note that this is just the latest in a long line of issues I have had with jeep. Please let me know if you or anyone else has a solution for this. Thanks
  • ebptspebptsp Member Posts: 1
    I hear a loud metal on metal rattling sound when i go over bumps in the road. i drive through richmond, va all the time and you can really hear it when i go over the terribly paved roads around there. I cannot figure out what the problem is. Before it was a sway bracing problem. That is another story about buying a vehicle from CARMAX...... (never ever do that)... if anyone has any ideas what it could be and how to fix i would appreciate the input.
  • sideburnssideburns Member Posts: 3
    my jeep was doing this as well...I took it to the Jeep dealer and the problem was that 3 of the motor mounts were bad and loose. That seems like the fix for your problem I bet.
  • sideburnssideburns Member Posts: 3
    thanks paule. if you dont mind, would you dig up the model you purchased?
  • gumball2gumball2 Member Posts: 2
    I have a '96 so I am assuming all is the same.

    There is no access to the drain (it flows into the space between the frame member that meets up with the firewall right in front of the passenger side)

    Drill a 1/4" hole right in the center of the round plastic piece that drops down to the firewall from the evap housing. Blow it out with air and plug it with a rubber plug or a bit of silicone.

    Hopefully this will take care of the problem. It did not fully take care of the problem for me. I continue to get leakage around the plastic thing that I drilled. I have used a lot of silicone but still get a little leakage. (which makes me quite mad)

    If you have any thoughts here, or can send me somewhere I would appreciate it. I am getting tired of working on this little problem. As is my wife, it is here car.

    Sure, I bought a Sony CDX-R5515X.
    Here is the link to the site I bought it from: Stereo
    I paid $165 for it but I see it is on sale for even less.
    One thing to note is that I already had the harness adapter installed on my Jeep because I had a previous Sony in there. I don't believe you will get one ordering through this website.
    Crutchfield supplies them free but their stereos generally cost more.
    You will also need an adapter to make the stereo fit (this is common when replacing a stereo).
  • mstoverinkmstoverink Member Posts: 22
    Just for clarification, the round plastic thing gumball2 is talking about is easily found if you pull back the top of the carpet in the front passenger foot well. It is a circle with a V shape coming out of the top. After you drill the hole in the middle, blow it out if you have an air source or use a long piece of wire to run up into the hole to dislodge any blockage. Once you feel the blockage has been removed sufficiently, I would suggest using plumbers putty (available at any hardware store) to plug the whole. It will give you a good tight seal and it dries solid...and it's PLUMBERS PUTTY...so it's desinged to stop leaks. Just follow the directions on the package, very easy to use. Hope this helps.
  • jmcc405jmcc405 Member Posts: 1
    I own a 2000 JGC and it is flashing its lights sometimes hours after the truck is off. It now also has a nasty habit of not starting. I am pretty sure there is a short in the security system. After many visits to get it "fixed", and after another no start, I shook the truck and it started. Typically when it fails to start all of the electrical comes to life in the truck and it simply will not crank. I am now trying to figure out how to either bypass the security alarm or disable it. Hope this helps.
  • nosligcnosligc Member Posts: 2
    Thanks for the response. If you find out what is causing the problem, please let me know. By the way, i have already had the light switch replaced, that solved the problem for a while but it is back. Just like everyone else, the dealer can not seem to find the problem, yet if this is an issue, which based on the number of cases I have seen by searching on the net it should be, you would think Daimler/Chrysler/Jeep would do something about it rather than give the customers the run-around. Thanks again.
  • topoftherockietopoftherockie Member Posts: 6
    I'm driving down the interstate and then it acts like someone just turned the ignition key to off and all of the gauges on the instrument panel seem to power down. I understand this happens because the PCM feeds the gages via the computer CCD Bus, so you really arn't seeing the actual voltage, temperature, fuel level or even the oil pressure. Your seeing what the computer interprets the voltage, temperature, fuel level and oil pressure to be. When the PCM overheats
    and shuts down, the gages are all zero'ed to the left but everything else electrical still works, starter, power windows, radio, horn lights, etc. etc.. The problem is most likely the PCM. The dealership has them on back-order for 3 weeks so there must be a run on them, place your $600 order early!

    You can test the gages by pushing in the Odometer button and turning the key to RUN.

    When the PCM overheats and shuts down the CCD Bus,

    1. The Volt Meter reads zero volts. It returns to normal or about 12 volts after the PCM cools for 30 minutes and reapplies power to the CCD Bus and the gages. The engine will crank, the power windows and sun roof still work, so I listen to the radio while everyone honks and gives me the finger while I block traffic for 30 minutes. Eventually someone will come and help push it out of the road while I spread my love and affection for Chrysler / Jeep products. Meanwhile, you just might see me in the slow lane when I feel daring enough to take it out of the garage. Feel free to stop and help me push it out of the way. We can share stories about the Jeeps of yesteryear for about 30 minutes until this one fires up again!

    2. The Tempreture Gauge reads zero. It was running at the normal 200 - 210 degrees before it stalled and returns to about 180 after the PCM cools for 30 minutes.

    3. The Fuel Gage reads zero. It was 3/4 full before the stall and returns to 3/4 after the PCM cools for 30 minutes.

    4. The Fuel Pump doesn't run for the 1 second prime cycle when the key is turned to the RUN position. Bypassing the Fuel Pump Relay by jumpering connections (30 to 87) causes the Fuel Pump to run continiously (so's my proboem isn't with the fuel pump). The engine will still crank, but it won't run.

    This seems to be an over-heated PCM shut down of the fuel and Ignition Systems evidenced by the gages all going to the left. It hasn't happened, yet, on 70 F degree days. The PCM is covered under the Extended Federal Emissions waranty for 8 years or 80,000 miles, I just turned over 82,000 miles and yes, Chrysler is alinating current owners and future buyers over 2,000 miles! It has been acting up for months and I have been buying the repair parts and discussing the problem with the mechanics in their dealership!

    As far as the overheating problem, a thermostat is under $10 from the Autoparts stores. As for the rough idling, I don't see the a through cleaning of the IAS (Idle Air Speed) motor listed in the stealers laundry list! I'd get a Haynes manual and clean the IAS before wasting too much more time with the stealer. Spark plugs and wires are a good thing to change along with the air filter every once in a while too!
  • topoftherockietopoftherockie Member Posts: 6
    Make sure that you read the forums regarding stalling and dieing or dies. I have a 4.7 V-8 and the electronics are different between the 4.7 and the 4.0. If your gages are not zeroing to the left when your Jeep stalls, then your'e probably dealing with something different like the fuel pump, fuel pump relay, engine ground, bad gas cap, the IAS or one of many sensors. My failed Crank Position Sensor displayed an error code when it died, unfortunately, it hurt the PCM too. If your gages show fuel and voltage but it just won't start, the Crank Position Sensor would be a good place to start.

    I worked with a fellow once, who had a flat tire the night before he traded his car in..he was a welder so he welded his wheel to the car because he aparently lost all of his bolts/// also why dont you try to hammer the back loose witha rubber mallet, if not a mallet then a 2x4 may do it, ...just dont be heavy handed and break anything

    I am new to this site. I am experiencing a problem with my Check Engine Light and have read every post regarding it. If anyone can give advice, it would be greatly appreciated. Thanks :)

    1998 Jeep Grand Cherokee (JGC) Limited
    65,000 Miles

    I haven't used my Jeep in 3 weeks. I started it up and door it for a drive to the gas station. Initially, I could not get out of first gear and assumed I must have a transmission problem. I let the Jeep sit and tried again. Now the gears seem to be shifting smoothly. The Check Engine Light is still on.

    Does it take long to go away if the problem is fixed?
    What are all these codes that people are talking about? How do I get them?
    Why else would this light go on?

    Thanks
  • gto1970gto1970 Member Posts: 2
    I did drill a hole in this today and water started shooting out at me. I blew it out with my air gun and it frains good now. To seal the hole I used a screw that had a shank smaller than the hole diameter but with a head larger than the hole. I put silicone all over the screw and poped it in there and wa-la it sealed.
    Thanks

    Please help. My 2000 JGC Ltd 4.7 when inserting the key in ignition, the gauges turn clockwise counterclockwise clockwise until key is taken out. Put a Sears battery charger on try to start the gauges act normal but still no start. I do get a clicking noise at the starter. With out the battery charger and after attempting to start I get nothing except the crazy gauge movements. Then I hear this rapid ticking noise down by the fuse box, but not when the battery charger is engaged. The battery is a Mopar battery that was installed 4 years ago. Could it be that the battery has lost its amperage and still read 13.5volts.

    Anyone have any ideas before I buy a new battery and starter.

    Thanks :confuse:
  • paulepaule Member Posts: 382
    Definitely try cleaning the battery terminals first. Corrosion on the terminals could cause those symptoms. Do a search on "battery" on this thread and you'll come up with some other old messages.
  • hbaradhbarad Member Posts: 9
    I have a 2001 Jeep Grand Cherokee. Recently the heater - A/C fan (or blower) quit working. Occasionally, it will kick on for 4-5 minutes, the quit again. The jeep has the automatic dual zone Heat / A/C, and the fan doesn't work in any mode. (Auto, A/C on Manual, Heater on Manual, Fan only). The fuse looked good, but I replaced it anyway. I'll probably end up taking it to the dealer, but since I don't have a clue, I'd like some hints as to possible causes. I read in another post that the blower motor resistor (whatever that is) is know to fail on another, older, Jeep model. Anyone know if that problem continues in the JGC?
    Thanks
  • halfpinthalfpint Member Posts: 1
    Would like to learn...

    Why is it that most Jeeps have a very heavy wind noise at higher speeds but then some are real quiet. For example two '04's, same body style, why would one be quiet and the other be loud?

    Thanks. :confuse:
