    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 referance?


    It's a common problem, at least up to '06. Air is directed around the HVAC unit by diverter doors which are controlled by vacuum actuators.

    The issue here is with the defrost/panel door being in the wrong position. This could be caused by: a faulty actuator, a pinched or disconnected vacuum hose, a disconnection between the actuator and door, or a faulty door in that it could be stuck, broken or dislocated.

    The actuators, doors, and their connections can be accessed on the side of the HVAC unit, which in turn can be reached from the drivers footwell.

    Can you drop me a line? I have a question about another DC product (Neon) that isn't appropriate here. My email is in my profile, but you may still have my work email address from our earlier conversations.

    For the last two days my jeep takes several tries to start- when I put key in ignition it does nothing several times...if I push it in hard and crank it starts...we have noticed for the last week the engine is louder almost a click clack noise. It has always been maintained etc. Took it to dealer and he informed that the cause was the timing chain which might make some sense as to why the engine is louder but not why it is difficult to start. Its got 114k miles I desperately need advice anyone familiar with this problem or problems????
  • Just got home after a nice day of driving in the hot Texas heat with the top off...made a brief stop at the grocery store and got back in the Jeep to go home and it made a noise when trying to turn over but never turned. I checked the battery cables and all was fine...nothing loose, no corrosion. When I opened the door, all of the gauges on my panel went crazy moving back and forth real fast...never saw that happen before. The stereo worked. Lights came on. Anyone know what the problem might be before I take it into the shop? Also, how many miles would a TJ go before having to change the alternator?

    On my way to work the other day, I stopped at a store to pick up something for lunch. When I started my jeep back up, it was making a knocking sound. My check engine light came on. It was the crankshaft position sensor. I replaced it. the light went off, but it is still making the noise. I will say that it still runs good, just making that sound.

    My 06 wrangler x has water on the passenger side floor...sometimes. I smell it and it is just plain water. I have checked everywhere on the inside of the cabin and can see no leaks. I make sure the control knob is turned all the way to the left so no vents or open when the car is parked. Any suggestions?

    I made a post about this a few pages back. I"m sure it is there. Most likely source is either the A/C drain vent or the gasket around the blower motor. Pics and process are there too...

    Sounds like multiple issues. MAY need to have the key cylinder checked to make sure all connections are good and that it isn't failing.

    If the timing chain is messed up you may have some bent valves or lifters. I did something similar on my Mazda 626 years ago and it never ran right again. Hopefully your issue is NOT the same.

    May also want to verify your starter, battery, and alternator are up to snuff.

    Sounds like fun. Verify that your battery is maintaining a charge. If it is the original battery, may want to swap in one of those gel batteries. They seem to do better in heat. I went through batteries about every 2 years out in the Cali desert.

    As for alternators, my 97 has the original alternator with 113k miles on it and it does just fine.

    Your other symptoms make me wonder if you have a loose connection somewhere. Your stereo should be wired in such a way as to NOT work with the keys out of the Jeep. Is it aftermarket? If so, I'd reconsider how you have it and any components (subs/amps) set up.

    Mac may have some ideas...

    My 97 makes a noise too, but it has since I got it back in 03. The 2.5 is NOT quiet, but it shouldn't be making a knocking sound.

    You sure the CPS was faulty and not reporting an actual problem? If the noise is continuing, I'd have it at least inspected to see what is up. The 2.5L is not an overly strong engine HP or torque-wise, so any problem that relates to the crankshaft and power generated should probably be addressed by somebody who can check that stuff.

    Sounds like a bad connection to me too, either power or ground, just as likely to be at the other end of the battery cables.

    How many miles will an alternator last?

    Somewhere between 1 and 200,000 miles! :)

    HI .. I have a Jeep Wrangler..2005..I and lately it has been having this bad shaking when i get up to 50 miles an hour.. it starts to plain of around 60 or so.. It has only happened a few times.. so i didn't think anything of it.. but today it was bad!!! It felt like the front tires were going shake right of the jeep... the steering wheel also shook a lot!! .. What do you think the problem is? The tire pressure is fine, and the tread on the tires are fine also!! I think the tires are the original.. they came with the jeep.. What do you think it is!! Thanks

    HI MY NAME IS TRACY AND IM HAVING THE SAME PROBLEM.. DID YOU FIND OUT WHY THIS IS HAPPENING? I WAS GOING AROUND 50 AND I THOUGHT THE FRONT WHEELS WERE GOING TO FALL OFF .. THE STEERING WHEEL ALSO!! THANKS TRACY

    has been covered a LOT in the Jeep Wrangler forum. May want to search there. But it boils down to a few things:

    1. Is your Jeep lifted?
    2. You running larger tires?
    3. Verify alignment and tire balance is good, especially with larger tires.
    4. Verify all linkages are tight:
    Both ends of the tie rod.
    Drag link ends.
    etc
    5. Verify that the knuckles and CV joints are still in good shape. If you jack up the jeep, you should be able to wiggle the tire just a TINY bit. If it wobbles when you grab top and bottom and move back forth (in and out). Joints may be worn.

    Can anyone help with this?
    During the last Cali heat wave I was driving home with the AC on high, and my '05 Wrangler spewed coolant out the overflow and down the side of the vehicle. I never noticed the heat gauge going much above 210. It did this same thing last summer ('07) on a trip to Oregon going through a very hot Redding. At that time I got to Oregon and replaced the thermostat just in case. It hadn't done it since, but I hadn't been in a situation where I was running fast at freeway speeds, in high temp. (95 degrees or higher) and was running the AC on full. I found a TSB Bulletin # 1801404 on a google search - but can't get the website to come up that speaks to it. One last thing, when I got home and parked it continued to gurgle a bit in the radiator or hoses. Any help anyone can give me before I take it to the shop would be appreciated.

    Most likely:

    - clog in the system somewhere
    - too much air causing bubbles to run fluid to overflow
    - water pump going bad?

    I'd recommend a good flush and inspection of the system.
