kad3338 Posted May 3, 2011 Report Share Posted May 3, 2011 When running the a/c on my 1996 STS, the two front drivers vents & rear vent blows hot air while the two passengers front vents blow ice cold. That happened the last two mornings when it was about 75 degrees out. On the way home it was 90 and all of the vents blew cold as normal. Is there some sort or temp switch for the drivers side or could a mix door be stuck? The passenger side has it's own temp switch that works ok, it's just on the drivers side that's acting up.
