A/C blowing out of passenger heating

[qdesa]

A couple of days ago, cold air began blowing out of the passenger side on my Jeep Grand Cherokee when the heat is on. Heat blows out fine from the driver's side, and the vents in the center of the car. Anyone have any suggestions on what might be happening? Thx.

I'm having the exact same problem. It only started about a week ago, but have no idea on how to fix it. If you find anything out, be sure to post it and let me know.

I have a 2002 limited with the same 50/50 heating cooling set up. In the shop manual it says with the engine running to hold down the a/c button and the recirculating button simultanously with one hand and then turn the driver side temperature knob one click CW. You will see numerical codes appear. write them down. To cancel just turn off the engine. Most likely it's the motor operated blending doors. I believe there are about 5 other letters prior to yours that explain it in greater detail than I can. All I know is that the replacement part is very expensive and the dealer has to have the car for 3 days. I'm bringing mine in next week and it's off the warrantee!-John

It is the blend door motor and they have to pull out the entire dash and fire wall to fix it. for a sum of $1000.00 none the less. i called chrysler about assistance on this as this should never break unless you have 200,000.00 miles on your car maybe then. The part is cheep but labor is 8 hours I am choosing not to fix mine and never buying another another chrysler product either . This is my fifth grand cherokee but this one sucks!!Heated seat is out also ,four brake jobs so far and it only has 50,000 miles it an 01.

This just happened to my '03 Limited with 45k miles and the dealer said $1k to fix. I told him I'll live with it for that kind of money. The dealer told me that he sees a lot of these failures. Clearly, a very poor design. I plan to register a complaint with Chrysler, but don't expect any help.

I called the 1 8009921997 gave last 8 didgets of vin number talked to woman telling her about brakes ,heated seats, power windiws problems and now this. I thought i was getting close as she gave me a reference number and had me on hold alot checking things out. I was sent to the next person she told me I am out of warrenty. NO SH@T!! The first lady knew this and said the issue warrented further looking into,but the second lady was not going to give me any assistance. This is my 5th grand cherokee and never again. Y ou would think by this time they would be building a tank with all the practice they have had but the foreign makers are kicking there butts. Arx300 lexus cost the same as a loaded limited yet a 2001 limited is barely worth $12,000.00 on a trade where the lexus is worth $18,000.00 all day. Good luck and if you find a place to complain let me know ,and good luck.

I've got the blend doors coming, there's two.(only $25.00 a pop) The dealer is telling me four hours to replace. I'll do it myself and tell you all the outcome. Maybe I'll make a tech post out of it with pics.

Hopefully I'll get to this Saturday the 10th of December, keep checking!

If I could of got it done for 4 hours labor I would have done it. You know I punched up blend door on search and found a guy that posted the whole procedure. It took him all day I beleive the whole entire dash has to come out and its like a puzzle I wish you the best. It was going to cost me $1,040.00 so I passed. Plus no gaurentee it wont happen again. Keep me posted maybe I will just pay you 500 bucks.....lol

Hi, this is qdesa, again, my old account wasn't working, so I signed up again. I think someone may have sent me some messages, but I wasn't able to retrieve them. Anyway, went to the dealer, and they said $1268 to fix the problem, not including the $100 they charged to diagnose the problem. Also, no air comes out of the bottom vents in the driver's side only. We have the extra care warrenty, and it was not covered under that, but chyrsler customer service said they'd split the cost with us 50/50.

Keep calling the Chrysler zone and raising a big stink. They will cave and work with you eventually. I saw that a lot at the dealerships I worked at over the years. (Jeep and GM, didn't matter). Keep going up the ladder. Get the news media involved if you can. Corporate will change their tune and fast if it looks like the public might want to get lawyers involved! Mooch lawyers might even start class action!

Used to piss me off royal to fix items that were way out of warranty and unjustified for the factory pay instead of customer pay. It serves them right to pay for a justified repair. Insist upon a "Customer satisfaction adjustment" as they termed it.

The dealer had the authority to make these adjustments too if customers bitched enough.

The problem was fixed this week, although it took over 2 days at the dealer. Plus, they only charged a deductible (346) on the warrenty, less than we had expected, for the blend door thing plus a fuel pump problem covered under warrenty. Only now the key sticks in the ignition... New problems.

I just joined and read all the vent door complaints. I had it "fixed" in june 04 on my 01 GC; now it's happened again. I also called Jeep customer service (800-992-1997) and they called the dealer. Norelief on the $827.50 estimate, because it was the "vent actuator" in 04, now it's the "midcase".
Don't expect the negative disconnect to workon a broken midcase, but I'll try it. Please respond with any success making Jeep eat some cost.

We have an '02 Grand Cherokee Limited, and are having a similar problem: only cold air on the driver's side, but the passenger's side works fine. I get the 52 and 54 error codes. I read that it might be (if I'm lucky) the blend door actuator motor, which looks like a potential DIY job, since it is right behind the glove box. I'm no mechanic though.

$1325 estimate from my dealer if they have to do the HVAC sub-assembly replacement. It's such a frequent problem that Jeep issued TSB (#24-001-04), which introduced the new sub-assemblies. Much more detailed info available at
