In looking at the car's manual, I see a left side and right side Air Temperature Door. It seems to me that this is likely the problem. Unless the control module is not sending the right information, which I suppose is a possibility. But for those who have my problem, does the simple reset work or does the problem return?
I am at my wits end!! Where to begin? This 2004 GMC Yukon problem is only on drivers side front. It has dual (slide) controls. Last summer the AC would suddenly stop blowing. Each time I would stop, turn off the ignition and re start the vehicle. Problem solved every time(5 or 6). I do recall a slight "ticking" sound when this was going on. Then it stopped. Then, while using the heater, only cold air comes out of the front drivers side vents. I did some research and changed the drivers side air door actuator. I took off (+) battery terminal, unplugged actuator(#604-106), replaced actuator, plugged it in, put (+) battery terminal back on, turned on key(without starting) waited 60 or so seconds, started and....... STILL BLOWS COLD AIR!!!!!!!
You can find in the headliner above the driver head where the little vent is
After You change the aspirator disconect the battery for a few minute. Reconect the battery, turn on the ignition and wait min 40sec without touch any button on the heater control. After 40sec You can start the engine and adjust the temperature

If not move out the actuator and check the door moving fee with hand. If is OK probably the auxiliary inside temperature sensor the problem
all other functions work fine heat / ac. Fan high/low every thing fine except changing were you want air to come out. Any ideas
My rear A/C is working fine, however, my front vents will only blow out cold air if I'm driving down the road/highway. If I come to a stop, the airflow is dead. Not sure if it is my blower, or possibly the blower resistor board (based on my research on these forums).
Any thoughts? Easily fixed, cost, etc...
Thanks.
Any ideas would be helpful.
Thank you

thank you,
Thanks for the comments
I am having a problem with my rear a/c in a 2003 yukon xl. NO air is blowing out of it, hot nor cold. The front air blows fine.
Does anyone have a suggestion? thanks
Have you had anyone diagnose the problem with your vehicle? How long has the concern been present? Thank you,

I could either just restart the car or turn the heat all the way up...then back down.
I recently started reading about this problem and did the relearn (pull the fuse under the hood) and now I have hot air coming out of the defrost all the time. I've tried relearning a few times (by the way).
Where do I go from here? I wouldn't think all my actuators went bad. Does that mean it's one of the control modules?
I've put a call into the dealer and explained my case. I stated that I know I'm out of warranty, but it's a well known problem that I did report. I mostly don't want to pay for them to guess at things. Willing to pay to get it fixed...only if they fix it...and just what's wrong.
Thanks for any thoughts.

I'm still amazed that GM won't admit something is wrong here.

Strange question...
Can I remove the actuator and move the door by hand....drive for a few days (knowing that side will be stuck on cold) then wait for the replacement part?
Let's keep the discussion here so everyone can benefit. We ask that people not post email addresses in messages posted to our Forums. Thanks!

Wow...that was a PITA.
Even getting the hush panel off was tough. That screw nearest the actuator...man. Who builds these things?
The screws on the actuators seem to be 5.5mm, not 6. I was killing myself on the back with a 6mm. My socket set doesn't have a 5.5, but luckily a 7/32 if memory is right worked.
I have my actuator out (52402588). Does anyone have a favorite cheap place to order, the right part?
I saw another post (dang if I can't find the link) that said some of the replacement parts were mis-labelled and were for the wrong side. This would allow the door to swing once and then get stuck.
