I'm about to partake the bewildering task of fixing my air-conditioning. The question I have is this: My cold/hot air lever does not slide all the way over to the left (it stops about 3/4's of the way). About a year ago I ripped apart my air distributor to replace the heater core and now I'm wondering if I put it all back together wrong. Basically, there's a revolving door within the distributor that diverts air either up into the defrost or down to the floor. My defroster does work and when I put it on heat it does blow out the bottom. Maybe the rod that connects the hot/cold lever could be out-of-adjustment? One-other thing, even though the A/C doesn't work, when I put it on max or normal it definately does not blow out of the dash vents. Does the hot/cold lever control where air gets diverted or is it just the upper lever that turns on A/C, heat, vent, defrost. Any ideas??
