Jeep Wrangler Maintenance and Repair Questions (1997 - 2006)

    Sounds like your dash pins that connect the cluster to the rest of the Jeep may be loose. Remove cluster (easy to do), clean the pins, give them a slight bend so they are all straight, use some dielectric grease to keep the connections clean and solid, and you should be good to go.

    Question for all you gurus. I have an 06 LJ Auto with only 8000 miles on it. Only some dirt roads and pavement - no serious offroading so far. About 2 months ago it started to *snap* or *pop* about 80% of the time when I started to move after coming to a complete stop. Stop signs, traffic lights, etc. It's a single loud *crack* that I can sometimes feel in the gas pedal. It makes some pedestrians turn their heads. It does not seem to matter what the temperature is outside, of the engine, or if I'm on the level or an incline - which drives me crazy that I can't get a pattern to the 20% of the time it doesn't do it. It does not seem to do this when coming out of park. Anyone else have this happen? It does not seem to be related to the brake system, and the auto tranny seems to be working fine.

    Thanks for the input. I saw that recall before I bought the Jeep and confirmed it had already been applied before I took it off the lot. I appreciate the thought though. I

    need to get it inspected in May (I live in PA), so I guess I can let the dealership say "I dunno what it is"... *grin*
  • erickplerickpl Posts: 2,735
    Perhaps try to recreate it in reverse?

    To me it sounds light it MIGHT be something with a u-joint. Do you hear any chirping while driving? Does it do anything in turns, or just from a stop?

    We own a 2006 Jeep Wrangler X. The check engine light came on and my husband took it to Autozone to diagnose it because they can get the code. It turns out it had something to do with the gas cap. It was reset. It came on again and Chrysler Jeep in Raynham, MA said it was probably the gas cap to refuel and tighten the gas cap and it should go away. It went away for one fill. It is now back on and hasn't gone away. We took it in for warranty service. It was the gas cap which is a known issue. I forget the code. In any event, they want to charge us $89.00 because my husband has a performance chip in the vehicle. I have the warranty that states that it only isn't covered if the performance or racing part is considered to be the cause of the issue, which it is not. Anybody have a suggestion on how to fight this. We have to pick up the jeep today. Thanks,

    My 2006 Jeep Wrangler sometimes gets wet on the passenger side floor. I have never used the air conditioning. Could this still be my problem? Wouldn't it be covered by warranty?
  • erickplerickpl Posts: 2,735
    Not likely.

    I used a BUNCH of RTV (the stuff you seal up the differentials with) and did the following:

    After having my passenger's side floorboard wet AGAIN after a bout of rain, I decided I'd had enough.

    I had previously attempted to stop it, but no go. Here's what I did. First off, remember that I have a 97 TJ and the cowl on those has a 'fake' vent over the passenger side.

    1. I removed the cowl by removing the 7 or so screws that hold it on. Then remove the wiper blade arms. I then RTV'd the underside of THAT to ensure water wasn't falling into the HVAC intake. If you don't have a 97, this is not required. But you will STILL need to remove the cowl cover.

    2. I then RTV'd around the HVAC intake itself. Looks like the previous owner had tried this and not done a good job, so I removed the silicon stuff and applied a liberal amount of RTV, ensuring there were no gaps, similar to how you'd apply caulk around joints in a shower or tub. I've seen covers you can put over this, and may consider that if it leaks again.


    3. I removed the battery and battery tray so I could get to the heater core area behind the battery. I removed my previous attempt where I used silicon and it was not holding up well at all. I cleared that off using a painter's tool, then went to town on the RTV. I could see the spongy gasket material that was getting saturated. I built up the area by the sponge and proceeded to RTV that entire area, including running up the side of the heater core/blower area so NO water would get in.


    If you look closely, you'll see where that gap in the metal had been and where the gasket was showing. I built it up a bit more after this pic and now water will not collect there, and even if it DID, there'd be no way for it to get in.

    After the rain we had last week, I checked it out and it was totally dry. :)

    I also have the A/C drain tube installed, in case people wanted to see that. You don't use the A/C that much, and this may already be in place, but worth it if it is not there currently - so when you DO use the A/C, it is good to go.


    So if you are getting wet floorboards, doing this may not totally solve your problem (windows/doors, windshield leaks, etc), but it will definitely stop one avenue of water.

    Air will blow on defrost and on feet, but will not blow air to the face (either fresh or A/C). When moving the lever to the face position, it begins to make a higher pitched whine sound, and continues to blow through the defrost vents. I am not sure if I am losing vacuum or if there is something that is hanging up the damper. Any ideas?
  • sadworldsadworld Posts: 4
    Hmmm. No chirping while driving, and I haven't noticed anything when turning, but I'll listen closer now. I only have the popping when leaving from a stop - and it was still doing it this morning. Thanks for the thought. I'll dig around on some other posts out there for u-joint problems and see if anyone else is describing my problem.
  • erickplerickpl Posts: 2,735
    You may also want to check your transmission mounts on your cross member/skid plate. If it is broken, you may have to replace it. Fortunately it IS something you can do yourself as long as you have a floor jack to hold the transmission up once you remove the skid plate. I THINK it is only about $30.00 for the OEM part...

  • erickplerickpl Posts: 2,735
    Sounds like the door that directs flow is not working properly. I know on Grand Cherokee's it is called a blend door, and I THINK it is the same thing on the TJ's.

    I have a 99 wrangler 4.0 5 sp. I was sitting in traffic today and it died on me. Tried to start it back would not start. Pushed it into a parking lot got in it and it started right up, any advice would be greatly appreciated.

    thank you

    I need to know what, if any sequence to remove a transmission from a 94 wrangler 2.5l 5 speed. I know I got about 6-7 bolts after I get through the skid plate, but after that Im lost. Never done any drive train work, I just need to know if there is a sequence in the bolts to take out so I dont damage anything else while I take this on. I plan on doing this tomorrow, well, today the 2nd of april, so the quicker the response the better. Get back to me ASAP. Thanks!
  • skimsurfskimsurf Posts: 6
    Im bettin starter. I got a 94 and if its anything like mine the starter is built into the flywheel. Did, it make a squeal when it happened? It may have just stopped up with the fly wheel, and pushing it just broke it lose. Just a guess, but it happened to me last year, and mine did that but didnt start back up, and I had to replace the starter, look into it. peace.
  • erickplerickpl Posts: 2,735
    I'd get it to AutoZone and have any codes read. It sounds like an idle sensor or throttle sensor if I had to make a guess. Both are pretty easy to change. I'd also check your plugs/wires/etc and see about doing a tune up if it has been a while.

  • tnc2008tnc2008 Posts: 2
    I bought a 99 jeep wrangler a few months ago and it had been doing great till it died on me in traffic and i had to push it into a parking lot. When i got it there i got in it and started right up. I heard maybe it could be a crankshaft position sensor. A few days before this happened my idle started acting up. It would idle up and down from about 700 to 1300 rpms. None of this started untill it started getting a little warmer outside.

    For some reason my blower only blows air out of the vents for the defroster, air will not come out of the vents on the dash board regardless of what setting the control switch is set on. Is there anyone who can give me some advise on what to check ??
  • erickplerickpl Posts: 2,735
    They are called blend doors and regulate the flow of air to the various vents. Fairly common on Jeeps, esp the Grand Cherokees (WJ's) but not uncommon on TJ's.

    Just went through this with my 04. The starter was seized just enough not to start on it's own power. Given the extra power with a jump it would start. Eventually it wouldn't even start with a jump.. Replaced the starter and it has been fine since... 10 minutes to replace the starter. It is easily accessable from under the vehicle. $95.- for a new one.....

    have a leak down by the bottom hose- replaced hose and still leaking - does any body have an idea - seem to be leaking fom engine - help 97 4 cyl
  • Thanks for your answer, Jeeper3, I have a 2005 X model and yesterday was super hot here in So Calif and the A/c did exactly like you described - all the cold air came out of the defroster. I found th vaccum hose on the intake maiifold had come off. I have 2 questions for anyone who can help: 1) the end of the vavccum hose that fits over the intake maniforld fitting is extremely loose fitting. Should it be tight? It appears to be holding but I was considering putting a tywrap on it but maybe it is supposed to be loose?? 2) there was a very slight amount of oil on the end of the hose and the intake maifold fitting- I cleaned it off but is this normal? The jeep has 7000 miles. Thanks again Jeeper3 and everyone
  • Hi Please check my message # 1238. It was a vaccum hose that fell of the right side of the engine on the intake manifod. I dont know why but it is an easy fix. Good luck
  • mac24mac24 Posts: 3,910
    1: It shouldn't be loose. Sounds like a clamp is missing, rather than a ty-wrap, if it's the vacuum hose to the brake booster that you're referring to.. Go to a Jeep dealer and have a look under the hood of a similar model.

    2: Yes, a slight amount of oil is normal

    I love my 2003 Jeep Wrangler I just bought it a few months back to replace a BMW. The weather down here in Florida alows me to drive around with the top down most of the time. Now the problem seems to be the same as others, when I turn on the a/c the cold air is blowing out of the defrost vents. it does not matter what function, heat, defrost, or a/c it all blows out the defrost vents.
    what should I be looking for? are there any manuals on line that I can refferance?
  • Hi
    I think your problem is exactly the same as my 05 Wrangler X . I assume you have a 6 cylinder (the 4 cylinder may be a bit different) - open the hood and look at the top right side of the engine. There is an intake manifold that is long and runs parallel to the engine valve cover. About 1/2 way along the intake manifold is a small fitting where a small hose fits on. My guess is the hose has slipped off the fitting. This happened to me and I just cleaned the hose off and reseated the hose over the fitting. Mine is real loose fitting so if it falls of again I will secure it with a Ty-wrap. This hose is small (around 3/8") and gose up from the intake mainfold and around the rear of the engine. This totally solved my problem and I am sure your a/c will be good as new!
  • Hi Mac

    This hose is very small, unlike the brake booster hose, and fits wery loosely. It dosent seem to be deterioriated at all. I will take your suggestion and see how these are secured on another jeep. thanks for your input
  • Hi, I had a 97 Wrangler Sport with the same problem. The 97's had horizontal sliders for the HVAC controls and the plastic clip on the the mpush/pull cable and the clip came off and the xcontrol operated but the cable did nothing.. I remember it was easy to clip back on and that should solve your problem
  • erickplerickpl Posts: 2,735
    of where this vacuum hose is? I'd just like to check mine. I'm curious now. :)
