'95 Grand AM
 

All that I have is one of $20 shop manuals from Chilton.
Would anyone know what switches the heat between floor, dash, and defrost? I would think that there must be some kind of valve mechanism that directs the air...
I can turn the selector and nothing happens. Heat always comes out of the dash... But with subfreezing temps, it would be nice to get some on the windshield...
All fuses are good, although I really can't say which fuse controls power to this heater entity...
TIA
