I just bought this car a few weeks ago, and while the people who owned it took good care of it, they wanted to change a few things around. I don't know anything about the history of how things were done, so this is totally guesswork.
The drivers side 2 vents will only blow hot air, the Passenger side 2 vents will only blow cold.
Before I realized that the pass. side will only blow cold I thought it was maybe a stuck vent, but now I am thinking that it is an electical problem.
The original stereo was replaced by a Pioneer unit that I have come to respect, but I am wondering if maybe whoever installed it might have screwed up re-connecting some wiring.
Is there a post anywhere that runs through how to remove and diagnose your control panel? (checking resistance values for the potentiometers and such) before I go tearing further into the dash?
Thanks
