Problem Reports

late August the AC would switch to heat for a few minuets and then resume with the AC,. as summer became fall I disregarded the problem till the 1st hard frost when after 5 miles little heat

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?

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!

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.

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?
