#1249 of 1888 A/C vent problems
Apr 20, 2008 (12:12 pm)
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?

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!

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

of where this vacuum hose is? I'd just like to check mine. I'm curious now.

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?
