    My jeep has been draining batteries for two years now, only happens in the cold months but can be assured that will have to replace the overcharged drained battery in the spring, mechanic cannot seem to pinpoint the exact problem, have resolved a few minor issues but cannot seem to fix the drainage problem, dont want to kill another battery......also it seems my temp guage gets stuck in the hot position check gauges light comes on, hear a swishing liquid sound and then the light goes off and guage goes back to normal???? actually, not for sure its the temp guage, its the right bottom guage and am assuming its temp???

    Thanks for posting this information. We bought a used 99 Laredo at was wondering why the guy said good luck. Passenger side window, air vents, and cruise control don't work. We fixed the break light thing. So if you could tell me how to fix the window, air and cruise that would be so wonderful. I haven't had the stalling problem yet but I have looked up the fixes for that too. Thanks again

    I have a 95 Jeep Grand Cherokee Limited (5.7L). While running all the guages shut down and went to 0 and all the electrical warning lights came on. The car continued to run ok but after parked and shut off the Jeep started but wouldn't continue to run - kept stalling. After a few attempts the Jeep will not start at all all! All lights, stereo, etc. are working but the engine will not turn over or even click. The Jeep died approx. 1 month ago for my daughter and we had it towed to a dealer who installed a new starter. Has anyone experienced anything like this?

    i have a 2005 jeep grand Cherokee lardo and about a week ago the heated seats would stop working and star back after the truck would sit turned off over night, then today the radio would turn on and off, service electroinc brake system would pop up on the dash the dash would start dinging, and last night my key wouldnt unlock the truck. but has all day today. i work at a ford dealership and have never heard or seen anything like this. this is actually my second jeep i had no probs with my 97 but i brought this one used only a month ago. if someone could point me in the right direction to look that would be great

    Have your mechanic check the CPS (crank positioning sensor) if he hasn't done it yet( cheep part expensive on labor) or the modle inside the distributer.

    Having the same problem replaced o2 senor map sensor, then know the muffler round as a balloon and backfired. the pcm screw was held by 3 screws and loose. when he pulls on the harness it shuts off. you are saying is is grounding out on the firewall. remove the bootom left bolt and stuff a shirt behind the pcm do you leave the bolt off. some one said in another post replace screws with plastic ones. we are frustated. it seems the pcm was replaced in 06 we just got this in sept 11. i do not want to replace this pcm.

    I'm not particularly knowledgable about such things but..... I have a 2001 JGC. I had a problem arise effecting both the heater vent controls and the cruise control. Both stopped working at the same time. I did some research online and learned that it was due to a vaccuum leak. Took the car to a mechanic and explained what I found online. He found and fixed the leak and both issue were solved. It was a very inexpensive repair. Hope that helps.

    Plastic screws will work too. I got too frustrated with having to go to the hardware store to buy the plastic screws. I had plastic spacers in my tool bag and placed them in between the PCM screws. I flipped the PCM upside down (meaning the harness is still facing forward but the PCM is upside down) and have not had a problem since. I played around with it and finally found a position that worked. For some reason the angle of the PCM mattered as well.

    I am experiencing the same issue with my 05 Jeep Grand Cherokee 5.7L. All guages drop to 0 and it goes into low (tow gear) and the check engine light goes off. I was driving the other night and everything shut down all at once and the Jeep stalled. It started back up and ran fine the rest of the way home. The check engine light is still on but I haven't driven it since then.

    To anyone having flickering headlights/interior lights issues - I have found a solution!! I had this problem for 3 years and finally found a specialist that immediately knew what to do. It's your light switch/turn signal. You just need it replaced. It cost me only $200.

    I have same exact problem now for past few months on 2005 Jeep Grand Cherokee .... Thinking it might be a fuse also but not sure ...??

    ((And also in addition to previous posts my jeep's whole electrical system instrument panel used to flicker on and off very crazily for no reason but when I would turn the jeep off and back on the instrument panel would light up normal . Took it to dealership and they never could find a problem and now it has not happened luckily anymore in the past couplen years ....))
  • bntjohnson79bntjohnson79 Member Posts: 1
    For several mornings, I have been woken up at 3 am or so for the alarm in my Jeep Cherokee going off randomly. I thought that if I pulled the fuse that it would stop. It did not. I pulled one of the other fuses related to the security system...to no avail as a matter of fact this morning when I went to start it to go to work. It would not start. When I put the 2 fuses back in it started just fine. What in the wprld could be causing this and what can I do?
  • todoguytodoguy Member Posts: 2
    I am guessing maybe a low battery.

    I've had similar problems. I got the car used (180,000 miles now) and I don't know how many owners before me, but I didn't get a door remote to lock and unlock the doors. Have to use the key. I found that if I lock the doors with the switch inside, shut the door and leave, the alarm goes off within 5 minutes. Have to use the key in the driver door to reset the alarm. Also had left the dome light on and the battery died. I couldn't get it started via jumper cables....lights just kept flickering and the ignition clicked....until I thought about resetting the alarm with the key in the door....and it started fine. It's inconvenient but door reset seems to solve the problem for me. Hope it helps.
  • todoguytodoguy Member Posts: 2
    I know this post is old but I've heard this a few times and experienced it twice myself.

    Once the battery went dead and had to have the jeep jumped, it triggered the alarm which kept the car from running after a couple of seconds. I had to reset the alarm. Since I don't have a door lock remote, I simply used the key in the door, turned it like I was locking and unlocking which reset the alarm.

    On mine, which is a bit old and beat up (3rd, 4th 10th? owner), if I don't use the key to lock the doors, the alarm will go off 5-10 minutes after I leave the car. Still can't figure that one out but maybe this will help. Good luck.

    im about to buy a 1994 jeep grand cherokee from an original owner and is in great condition for 1.600 was all fired up about it then saw the reliability marks when it came to transmission and driveline issues and elrctrical, and even the 4 wheel drive! however the classic didnt have those low marks in any category. ive owned several xj's in the past, great wheelers and reliable daily driver, however i was looking forward to the much cleaner and more luxury insides of the grand cherokee, it has the same engine as the xj, the 4.oliter. can anyone tell me something good about the zj, or am i making a mistake choosing thezj over thexj, could use some opinions on this matter
  • skjeepskjeep Member Posts: 2
    My 2005 Jeep Grand Cherokee,had these problems .
    On startup no gages,no warning lights,no read out from the status control pannel, and no turn signals.
    Removed negative battery terminal connector for an hour then reconnected it to the battery.
    This seems to have corrected the problem.

    no need to wait 30 minutes. 30 seconds or count to 30 did it for my 95

    I purchased a new 2011 GCL V6 a couple of months ago. All's going well EXCEPT I've had three battery failures so far the last being Xmas Day. Car not driven for three days and battery dead flat. Roadside assist got it going. Now have no radio or other panel features. Screen blank. Never in my 40+ years of owning cars have I experienced this. My other car is a Mercedes C Class 200K and all we do is put fuel in it. It is a perfect vehicle.

    Last trip to the dealer found no fault. Second failure they changed the battery and now three weeks later back to square ne.

    Any thoughts?
  • skjeepskjeep Member Posts: 2
    One of two things is causing the problem. The battery is getting discharged due to a short, or the battery is not being charged when the GCL is running.
    Because the radio and panel features stopped working. the best guess would be the wiring to the automatic switch assembly(or the assembly itself) that allows the radio to stay on when the switch is turned off until the door is opened.
  • djwilito83djwilito83 Member Posts: 2
    So far I have seen Power control module issues, ignition key issues, and pretty much electrical in general as far as i can read, My 2006 Jeep Laredo has now stop working as a result of flickering lights and the car not being able to come on? IS there any way to find out if we can get these electrical issues to be recalled? Anybody else having problems with their 2006 Jeep Laredo????? PLease reply, maybe we can all start a petition and turn it in to the NHTSA!!!! :mad:
  • sstrpud24sstrpud24 Member Posts: 1
    At first everything in dash went to zero gas showed none speed went to zero. Now it will start but than die. Everything else works but just won't stay started please help
  • djwilito83djwilito83 Member Posts: 2
    Same thing is happening to my '06 Laredo
    We need to start calling this number from Dept. Of Transportation
    NHTSA to make this issue become a recall, 1888-327-4236
    Spread the word! We don't have to pay out of pockets if it becomes recalled !!!
  • zjorvis95zjorvis95 Member Posts: 1
    If it's the factory installed alarm, you can just not arm it instead of pulling the fuses. With the doors closed use the automatic door locks to secure all doors & liftgate. Then exit the driver door and either slide the lock manually and close the door or close the door and lock it with the key (not the fob.)

    If the alarm works all day at work with no problem, I would consider that someone is screwing with you. Maybe they don't like where you park or something.

    Alternatively, maybe your battery is running down after X hours and your alarm is responding to the drop in current.

    I just had my 1996 jeep for a little over a month and already having electrical problems. My dash board doesn't work and the radio don't play. If it is the brain in the jeep how do i find that out. The fuse blew and if you try to put another one in as soon as you touch it the fuse blow again. every thing else works fine.
  • sooner26sooner26 Member Posts: 1
    I have a 1996 Jeep Grand Cherokee. The car stalls on me while driving and the back window goes down intermittently. The battery is new and I have replaced some electrical wiring. I have read that it could be my crankshaft position sensor or my computer box.

    Any help would be appreciated.
  • kpelleykpelley Member Posts: 2
    I have a 1996 Jeep Grand Cherokee. Lately, there have been some intermittent problems. At first, it would occasionally not start due to a dead battery, but with a quick jump, I was back on the road, but wasn't sure what was drawing off the battery. This I had to do about 4-5 times. Then, it happened and I had full power, but had to keep my foot on the gas in order to keep it from dying. Last week, while driving, everything cut out, the radio, the lights, the dash, everything but just for a second, then it all came right back. This happened a couple times. For the past week, I haven't had any issues at all, until this morning. I started the Jeep and it started fine. I pulled out of driveway, put it in drive, but had to stop to let someone walk by. At this point it just died. I tried to restart it, but had no luck. I turn the key and it sounded like it wanted to start, but didn't- there were no dashboard lights when I turned the ignition, no lights, radio, etc nothing. I got it to start once more and was able to get it in to a parking lot before it all cut out again. At this point, the steering wheel won't lock, nothing is getting power, not even my locks, although it stills sounds like it wants to start. Please help!!
  • ryelenikryelenik Member Posts: 8
    I had kind of the same problem with my 94 GCL. The first thing I would look at is if the check engine light is coming on when you first turn the power on. Don't turn it clear to turning over, just powered up. If the check engine light doesn't come on and it won't start it is more than likely you computer. Sometimes my light wouldn't come on and it wouldn't start. I would wait a while with the key on and the check engine light would eventually come on and it would start right up. The time waiting for the light to come on was longer and longer until it just didn't come on and wouldn't start. There were also many other things going crazy like yours is but I figured out the check engine light was the main giveaway for it being the PCM. I bought one from ebay about 2 years ago and haven't had any problem since. Hope this helps and good luck.
  • kpelleykpelley Member Posts: 2
    At this point, absolutely nothing comes on when I turn the key- not part way or all the way. I am having it towed now. Will I be able to pull a code off it still if its the actual computer I have to replace? Are there any other tell tale signs that I should be looking for as well?
  • thecez01thecez01 Member Posts: 4
    i have the same problem with my jeep mines a 5.2l v8. i changed a lot of parts the only thing i have left to do i my crank position sensor or my neutral safety switch. ive also tryed three different ecms and nothing.

    if u get it running can u please help me by letting me know what u did.

    thank you
  • bigbadwolf1bigbadwolf1 Member Posts: 1
    I have a 95 JGCL 5.2 liter with factory alarm. I've had this truck for over 12 yrs, and I've had this problem for probably 5 to 8 yrs.
    with the doors are unlocked, if I open a door the dash lights and the 4-ways start flashing, I have to hit the power unlock switch to turn off the flashing lights or it wont start, If the doors are locked, I have to unlock the passenger side door or the alrm will go off, even when I unlock the passenger side door, the lights still flash and I still have to hit the unlock button.

    I have cut the violet wire with the yellow stripe, that comes in from the fire wall on the drivers side floor board, and grounded it, that was supose to have disabled the alarm, that didnt work, and I have even removed the security alarm module.

    the alarm doesnt come on now when I unlock the drivers side door, but the light still flash when I open any door, and if I dont hit the unlock button to turn em off, it will drain my battery.

    does anyone have a clue as to how to fix this??????
  • redjeepladyredjeeplady Member Posts: 1
    Car is 5 months old, less than 10K miles: Replaced radio/navigator three times and it still stops working intermittently. Dealer said no one else has problem, suggested another replacement.

    Now alarm goes off intermittently, once while car was running and I was parked, another time when no one was even near the car and I was in a building. Don't dare lock it. Dealer says can't see a problem.
  • fuzziestumpfuzziestump Member Posts: 1
    Can you expand on this problem? I have a 2006 Dodge Ram 1500 with the 5.7L V8 and the 45RFE transmission - 3 days ago, my heater vents went a little off (the floor vents stopped working) and the day after that, my CEL came on, and I have no automatic shifting - cant manually shift into 1st at all, and can only manually select 2nd, or D (which I'm guessing is limiting me to 3rd gear only). I'm about to drop $327 on a transmission control module, and would like to avoid that if it could all just be from a vacuum leak. would you mind linking us to some of the stuff you've read online about this? (Haven't tried cruise control, but I wont be driving this vehicle until it's going in for repairs)

    Thanks!!

    I had my alarm going of randomly in my '95 Grand Cherokee. The fix was easy. Remove the drivers door panel, in the lower left part you will find a connection that runs up to the door key lock. Unplug this and put a jumper in the end that comes from the front of the door. Tape this up well and leave it unplugged. The jumper grounds out the factory alarm and you will never have alarm issues again.

    i have a 2011 jeep GC and just found out that this year did not come with a red battery battery warning light. i have looked at 5 or so same year and all do not have it. the manual say it is to come on at start up for a bulb check and then out. all other warning lights come on and out. you tube has a video about this and tells that it has no battery warning light. does any one else no about this.

    Hi, I have a Jeep Grand Cherokee Overland 2.7 diesel 2004 model. I can not lock the doors with the remote control, nor locked doors. I have changed batteries. I have two remote control and it is the same for both. Interior light on the passenger side does not, can not discontinue the mirror on the passenger side. Some who have experienced similar and have proposed a solution?
  • wpatterswpatters Member Posts: 54
    When in Auto headlight mode the dashboard lights come on and you can hear the relay click on when it gets dark BUT the headlights do not come on. They come on when you move the switch to manual. Is there a particular fuse or relay that just controls turning on just the headlights? If someone can tell me exactly which one controls that I will replace. They are not cheap so I do not want to experiment.
  • mgrgrymgrgry Member Posts: 1
    This sounds similar to the problem I also have ,but fixed today I'll tell you what i did and see if it works for you. When you open the passenger door there is a rubber grommet that the wires for the controlls go thru. Try and slide it back from the door side (do not cut this because it keeps moisture away from the wires) and see if there is a black wire ( its the ground for the passenger side controlls) if its broken find both ends and butt splice together. You can also add a small piece of more flexible wire to help this from happening again. With that wire broken i had no pass side controlls and the int. lights stayed on and the keyless entry would not work.

    Also check the driver side wire just in case. :)

    Hope this helps
  • nick117nick117 Member Posts: 1
    I also have a 2011 Gr Chk with low mileage and the Sirius radio loses connection under even the smallest of overpasses. Along with that, the front charger doesn't work; the key is not detected on occasion; left rear blinker went out (took 2 and 1/2 years on my other cars to need a bulb); and the navigation keys do not punch in. Mostly electrical issues. They replaced the navigation system yesterday and it seemed to help the sirius xm situation. However, now the front charger doesn't work again.

    Does your entire radio/navigation stop working or just Sirius xm? Hope I don't have to look forward to my alarm going off next.
  • ozjeeperozjeeper Member Posts: 5
    I had this problem too. The dealer tried flashing the module. They checked the bulbs. No result. I was sure it was the stalk but they told me if that was the case nothing would work.
    So I put pen to paper and wrote to the service manager with a copy to Chrysler's headquarters here in Australia. I told him that I would pay the costs if the stalk was found to be OK.
    It was the stalk. They replaced it under warranty and Chrysler also followed up to make sure I was happy.

    So try it. What I have learned is that if Chrysler don't issue a recall or fault docket then the dealers won't look at it.

    They still haven't issued a recall for these faults so maybe it would be worth it over your way.

    You can quote me.

    Any help will be great

    Thank you
  • barryzbarryz Member Posts: 43
    I am pretty sure what it is, i had the same, and found the answer on forum. The ground wire from your window control panel on door probably broke in 2. The common place it breaks at is inside the rubber boot you will see that covers wire harnes leaving door and going into car near the hinges. Pull back the boot, look for a big black wite that is much thicker than all the others, it is the ground. It is such a thick stiff wire that the constant bending as you open and close door over the years will eventually break it in 2. It still may have a few strands not yet broken. I easily fixed mine by stripping off a little insulation on each side of break and putting the 2 broken pieces inside one of those twist on wire splices that looks like a little cap, get them in electrical dept at home depot or ace hardware. It did not look broken when i first looked, put i pulled on it and one end came out, i had to dig in bundle to find other end. Others say to replace entire ground, thats a lot more work, mine has been fine now for 6 months, if it breaks again i might splice an extra piece in to make it longer. i have a 99 grand cherokee laredo. Post a reply to let me know if you fixed.

    If anyone can help, While I'm driving my 2006 Grand Cherokee it runs fine, Sometimes while I'm stopped and on idle, my RPMs drop and it starts to sputter like I'm running out of gas. It has stalled out once from this. HELP!!!!!!!!!!

    i have a 97 jeep cherokee lareado that shuts off sometimes takes hours to crank sometimes cranks right back. The other day all the guages went crazy and the headlights flicker off and on. Any help out here? Thanks
  • mistystilesmistystiles Member Posts: 1
    Hi there. I bought a 96 GC laredo last year. Ran great at first, but then started having a dead battery in the morning or after a few days of not driving it. Changed the battery. Still dead. Checked alternator, everything is fine. So recently I have had other problems like the stero staying on after I turn car off and even lock the door from the outside. Now the alarm has been going off randomly. And the ahzards went off the other day. I have to jump it everytime time I drive it now. The windows also will continue to work after the key is out of the ignition. Any suggestions on what I can do? I really love the vehicle but I dont want to dump a buch of money into an older rig like that. Any help would be much appreciated! Thanks
