Question about 1994 Chevrolet Corsica

1 Answer

1994 corsica The button on the heater adjustment where you can change it from the vents to defrost is stuck in the vent only and each time I try to switch it to another position it doesn't change. The blower fan is working as it should. I don't know whwere to start even looking for the vacuum to get it fixed. Can you help? Tell me where to look for that vacuum that controls the switch.

Try pulling out the switch itself. I have the same car n had same problem. after pulling it off I noticed it was broken. I was lucky enough to have both pieces. so all I had to do is glue it back together.

1998 chevy blazer heater problems. wont switch from defrost to floor. stuck on vents right now. how do I fix this problem.


Most likely either the vent switching mechanism is dirty and won't switch the flaps -or- most likely the vacuum that is used to turn the vent flaps is either leaking and not pulling enough vacuum. You will have to get underneath the dash near the center, to check and see if you can manually move the vent flaps. If so, then most likely it is a vacuum leak in a vacuum line to the flap mechanism.

1986 Chevy Nova - the defroster/heater vents stopped working. Any ideas? Before they found the found the fuel filter, they messed with the air filter. Could that be the problem?


If the air vent mode doors are vacuum operated, (though some are cable operated), they could have disconnected a vacuum line from engine. A vacuum diagram sticker should be located under the hood. The a/c hose will be listed as (HVAC hose).

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.

Cold air comes out the defrost vent all the time. 1994 buick le sabre. no air comes out the front registers.


The most common cause is the blend door actuator. It's the door that diverts air between the floor, vents, and defroster. Sometimes the part will get stuck in 1 position. Some cars have cable driven blend doors, others are electronic.

1990 Chevy Corsica heat issue


I think your on the right track with the vaccum/heater issue. Its not the core if its just not blowing out of the right vents. Find the plunger on the side of the hvac box that controls the selector door by squeezing the plunger by hand to see if it changes what vent it blows out of. If it does change when you do this, its a vaccum issue between the plunger and the vaccum bar. Trace the vac line from the plunger back to the bar, I bet you find your problem.
