AC vents
 

Hi, Iown a 2000 coupe and I have a problem with the AC blowing through all the vents. I assume it's an electrical thing. I recently had the AC compressor replaced and that's when the vent issue started. I thought I would ask here before taking it back to the mechanic shop. Anyidea as to why this is happening and how it can be fixed?

Thanks,

Hi Rick, under the dash there's an actuator that opens and closes a door on the air box to divert the air to the desired location, floor, bi-level, defrost etc., I believe it's controlled by vacuum that goes through a vacuum canister, from the motor.The actuatorcould either be not functioning, it could be stuck,or may not be getting a vacuum. The selector switch on theAC controls on the dash, controls the actuator. So there's a number of things that could be causing the problem. Since the problem started when you had the compressor replaced, it's possible that a vacuum line could have been knocked off while they were working on the compressor.
