The vents facing the driver blow out hot air when the air conditioner is on. Sometimes it goes back to cold and there have been times when I have to pull over to restart the vehicle. I just turned the heat on, and now cold air comes out then heater is on. Is this a recall problem?
2004 Chevrolet Tahoe 92,000 mi,
In AC mode, heat eventually comes out on drivers side. I had the actuator replaced by mechanic at a cost of $300.00 ($150 for the actuator and $150 for labor). New actuator worked fine for awhile now it's doing it again. Anyone have any suggestions or instructions on how to install new actuator?

When the heat setting is on heat is only in the front the rear heat vents do not blow hot only cold even when the rear heat setting is on hot.
2005 tahoe. have noticed rear a/c blowing hot if it is on at the same time or before front a/c. have to turn all a/c off, turn on front, then back and it usually works. sometimes have to restart the vehicle to get it to work. just replaced the battery and fusible link cable between battery and alternator, now the passenger side is blowing hot. since we're at the 39th day in a row of 100+ outside, i don't need the heater. i've read other blogs and it seems to be either a mode selector motor or actuator door issue, but i haven't seen anything definitive. can anyone help, please!

AC blows hot. Have to turn off engine and turn back on and this seems to fix until next time.
trying to get cold air thru the dash vents is a hit and miss deal. air will go thru the defrosters for the most part but in az. this takes a long time to get the inside cool. has electronic air front and rear .all air coming out is cold but just the wrong place
when air condition is on hot air blows on drivers side some of the time.. If I turn the vehicle off it will reset it. Same thing happens sometimes on passenger side.
Driver and passenger do not heat evenly. Have not fixed yet
My front vents are blowing cold air but my heat is working in the back? Is it expensive to fix this problem

At first, hot air would blow out of the passenger's side while the AC was on. Next the AC would quit on the driver's side and blow extremely hot air (hotter than just the heat). I can get the AC back on only by shutting off the vehicle. The switch from AC to HOT seems to get worse starting about @ 85 degrees and when it's @ 100 degrees the AC stays on a very short while. When the AC is working, it is very cold.

after dealing with the on off hot cold issue for a couple of years it finally went all hot and no cold. I had the actuator replace parts and labor was right at $800.

Only cold air comes out of the driver's side vents, no matter what temperature is set it at in my 2005 Chevy tahoe
