#201 of 299 2004 GMC Yukon Denali Passenger A/C Problem by snerem

Sep 16, 2010 (9:52 am)

I have recently been having problem with the passenger side A/C. The rear A/C works, as does the driver's side, but the passenger side blows out VERY HOT AIR. Even when the entire unit is off (no heat, no A/C...just off), we can still feel hot air coming out by the floor. We've even shut the vents on the driver's side but can still feel the hot air blowing out. It's getting to the point where my radio/dashboard is getting warm/hot to the touch. Any ideas of what the problem could be?

This is the information that was given to me. It worked, and we have been having no more problems. Good luck!
 
Owners need to re-program the climate control system which I did successfully.
Disconnect A/C & HVAC fuses.
Start and run for about 30 seconds, turn off.
Install HVAC Fuse only. ( A/C fuses leave disconnected )
Start and while driving turn on climate cold setting and run through the different controls, foot, vent, defrost etc. making sure the system is working properly several times.
Turn vehicle off...
Start and re-do sequence several times.
Turn vehicle off.
Install A/C Fuse
Start while driving turn climate control on with A/C...
These steps resolved the problem, re-calibrating climate control systems memory.
Again, this should be a recall issue and thousands of loyal GMC customers are being charged $1,400 or more from dealers.

I have been having the same problem on my 03 Yukon XL with the A/C not shutting off when the car was turned off. I took it to the dealer where they charged me $417.64 to rplace the HVAC Control Module and repair wiring. One week later, my battery went dead and had to be replaced and they charged me $$137. I thought there must be a connection, but was told no. I have had numerous issues with this vehicle as well. I have always gone to the dealer. Now two weeks later, the bearing assembly needs replaced to the tune of $1300.

Another successful re-program of the climate control system. Thank you. I followed the steps to the T and everything is working fine. I'm sure you saved me hundreds. If I knew anything worth while about cars I would love to share. But I don't. Big help,
Thanks Again

Your welcome !
I also know little about working on new cars but refused to pay $1400 to dealership knowing this issue started because of a dead battery. Dealership knows hundreds of thousands of customers are dealing with this issue and you'd think they suggest the steps to correct I listed FIRST...no, they want $1400 for doing nothing.

My fan will not blow air in the front unit even when putting fan to the max. Also when fan does work it may keep running after the vehicle is turned off. This is an intermittent problem but seems to becoming more regular. The rear unit works fine. Help any advice?
