Re: 2004 Tahoe AC goes to heat in both front and rear
Yea, I put the new rear control module and that seems to have fixed it for now. However, when I first put the new module on it would only blow through the roof vents; the temperature control was fine. I had to unplug it then plug it in and that has taken care of it, until last night when it did it again; stuck on roof vents. At least I can still control the heat. My original problem was stuck on cold only. I did the nut and bolt on the temp actuator to keep it from over traveling; it worked great for 3 years. Then I had the get stuck on HOT problem, that shutting truck off then back on would fix - every time! Ever since the new module the temperature control is fine. Now it seems the actuator for the roof and floor control sometimes get a little stupid and gets stuck on roof, but I can live with it, so long as I can still regulate the temperature.
