I have the same problem in my tahoe, but now that the actuator is stuck in cold -position, I haven't got any intrest to fix it, maybe when it's gettin colder and I need to get some hot air into the truck.

I know this a old thread, but its a very helpful thread, thanks whiteout, should definently be a sticky.
But my a/c just stopped working, bad blower motor, replaced w/ new blower motor. But its not blowing hard like it should. I got it once to push air like i used to, even w/ the recirc. air on, but now its just barley even blowing air. Is this the actuator going bad also? Should i go ahead install the actuator also and then disconnect battery like stated to have it all work properly? Also, i have the digital climate control.

Does this also apply to an '02 yukon with electronic climate control? I have the hot air issue from time to time when I first start my truck and it idles for a few minutes or I pull over and it idles for a few minutes, hot air starts to come out of the vents. But as soon as I start driving it cools right down again. Any ideas?

smurphy80 I had this same problem and my system was over charged. When sitting idling the pressure would build up and sometimes it would even kick off the compresor.
The shop pulled it down and recharged it. The air is cold but only in the back. It blows only cool air out both sides of the front vents. I have disconnected the actuator above the hump and move it by hand and it would get no colder. So I am still tryin g to figure thie out......Scott
