#64 of 109 Re: 2004 Yukon Rear Climate Control [bbebensee] by tjustus May 11, 2008 (2:07 pm)
Replying to: bbebensee (Jan 17, 2008 3:14 pm) I am having the same issue... My rear climate control will blow out cool air, when I'm calling for warm-hot air. What came of your situation?? Also has anyone else had a similar issue and what was their experiences??   A separate issue... While blowing A/C the front vents start blowing HOT air. I have to turn the vehicle off for this to stop.   Problems we should not be having for this type of automobile.

they say it’s common problem for this kind of Suv’s after a few years on the road. Well i say Bull S**t. Anyway, there’s a “cheap” way to overcome this dilemma … you see the hot air pipes (there are two pipes coming from the compressor going to the firewall, you’ll find them on the right back corner two black rubbery pipes next to each other) these pipes are responsible for the hot air flow in your a/c when you disengage them use sparkplug to plug it, make sure it's pluged (don’t put it back in just set it away from any moving parts) that will stop the hot air and you’re a/c will start to get cooler than before, you put right back again in the winter. OR, you may unplug the battery for 10 min. then put back and see if the a/c is working well or not keep in mind that the ignition key must be on START during this process. Good luck, Note: you can do it yourself on a Sunday it will only take 20 min. to do it.

Over the past three years we have had freon added to the system and each time we add a small amount it stays cold for a period of time. Each time this period of time is shorter. The last time it stayed cold for about 3 months only. The last two times the mechanic added dye to the freon and both times could not find a leak. Any possible solutions.

I still have no answer as to why when I turn on my heater, the only vents that blow warm air are in the front. The back vents never blow warm??????? 2004 Yukon. I have disconnected the battery to default the computer no luck. The fuse is fine. The vents are not plugged the airflow is fine. Again this only happens with the rear climate control.   CAn some one please help before Winter sets in, last winter was cold!!   Thanks Replies to this message: arrie (Sep 29, 2008 8:15 am) B4UBuy (Jan 15, 2009 6:24 pm)
#70 of 109 A/C problems 2002 Yukon by wilbanks Jun 30, 2008 (5:34 pm)
I have climate control. The A.C works sometimes and blows cold air and the it will turn off and A.C button on the bottom of control panel will blink and A.C turns off. And come back on after a while then back off. What is this a problem with the control panel? Replies to this message: rsht (Jul 20, 2008 6:34 am) stearnspk (Jul 21, 2008 6:20 pm)

Replying to: jlflemmons (Aug 01, 2007 8:16 pm) Yep, can confirm the "pull-the-fuse" fix. I replaced the battery in my '04 XL Denali, and the front A/C would only blow full heat (I could control the fan, but the temp seemed to be max heat regardless of the panel setting). The rear controls seemed to work fine. I disconnected the battery a couple of times (key off) thinking that would reset, but apparently not. After reading this thread, I pulled the (front) A/C control fuse (I forget the label, but there's one for the front, and one for the rear), and drove the thing out to dinner. When we came out, I put the fuse back in, and was relieved that the system seemed to return to normal. Never had any prior issues with climate control. Thanks!!

Replying to: wilbanks (Jun 30, 2008 5:34 pm) Just my guess, have you checked to see if your AC system has the proper level of 134a? Replies to this message: stearnspk (Jul 21, 2008 6:20 pm)

Replying to: rsht (Jul 20, 2008 6:34 am) We took it in and had the problem fixed. It ended up being a small hole made by the screw in the rear mud flap that caused a small leak. It was covered by the insulation so the dye was not visible where it was leaking. Thanks for your help.
