My girls Hvac is having an issue thats even baffling the mechanic. I'll try to explain this as best I can.
Ok so the heat to the upper (face) vents doesn't work, here's what I do know
1) it CAN'T be the heater core, Heat blows to the feet and windscreen.
2) heat WILL NOT blow to the "face" vents.
the mechanic doesn't know what the hell is up, we took the headunit out and could see the arm moving that directs air flow physically moving, so thats not broken..
The mech. had deduced that the face vents are tying to blow hot AND cold air at the same time(resulting in well..not hot air), so he programmed the car to only blow hot air all the time (its winter) this is temporary... but still, why the hell would it only blow room temp air out the face vents and not hot air?
It's a 2006 SS if that matters
