I have a 91 Camry. In this model there is a manual switch that moves air from forward facing A/C vents to an A/C vent that blows up/back. Generally I have it switched to the front blowers, unless it's really hot and there are people in the back who need air for a few minutes.
This has worked without any problems until a few weeks ago. I switched it to the up/back position and the air changed to the upper blower vent as expected.......now trying to switch it back does nothing. The switch feels and sounds just like it did prior, I can switch it up and down, but it does nothing now.
Any ideas on what I could do? My guess is that I need to tear the dash apart to figure out how that worked, but I'm not even sure where to start there.
thanks
