Fan blowing warm air only, and only through the defrost vents


Had the problem been solved after you replaced the damper door switch and had the gas checked in the ac system??

A/C will only blow through defrost vents


Common question on this site. On late model cars, the vents are controlled by blend door motors. Small electric motors open and close doors to direct air flow.
Chances are you have a blend door that is stuck or a failed motor.
The default position is the defrost to make sure the windshield is always clear.
Someone will need to look behind the dash to see if all of the doors will move on demand.

91 ciera only does defrost, no vents or AC


i believe this is a vacuum operated system. if there is a problem with the vacuum supply to the control unit, it will automatically default to defrost. i would start by checking the vacuum source lines. good luck!

Driver's side air blowing warm, won't change


Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

Defrost blows cold air


Sounds like you have a plenum door that is not opening when you go into defrost mode. You will have to check all your vacuum hoses and switching valves under the dash to see which one is not working. Hope this helps.
