2007 Chevrolet Cobalt Vent Selector Switch Not Working Properly
My 2007 Chevy Cobalt's Vent Selector switch does not change the air flow from floor / vent / defrost. Fan is good - air flow just does not change location.
The switch is working otherwise as changing the vent selection does cause the "inside/outside" air switch light to come on and off depending on the location of the selector switch. This leads me to believe that the switch is not bad and it is not a fuse problem.
Could the problem be due to the ventilation air filter?
What is the process of checking the ventilation deflector / actuator?
