Vehicle - 1998 Blazer LS 4WD, manual temp/AC controls
Symptom - Heater blows or trickles hot air all the time, even when turned to the off position. Will not blow a/c cold, though a/c tests good. Hot air will blow where it is supposed to i.e. - defrost vents, floor or dash.
I have read a few threads here and elsewhere, such as:
If it is the temperature actuator, can anyone confirm this is replaced through the "center control panel" where the switches are located as indicated in the first thread listed? I couldn't quite tell. In addition, what is the part number and a purchasing source for the part.
If it is the blend door, while I dropped the glove box, I still couldn't locate the part. I will post pictures if this is the issue.
Great forum, total newbie, shade tree mechanic. Thanks for being here for us "idiots"!
