As you probably read on here last week, I had to replace the vacuum pump. When I got it back from diagnosis, the a/c would come on but wouldn't blow... like the doors weren't opening to the a/c. They hooked up it up their computer, reset it, and everything was good. Tonight the problem happened again. Driving down the road, the a/c comes on, but no air blows. Any idea whats going on?

Do you have the vag com scanning tool?

do you hear the AC running but just no air from any vents?

does hot air comes out if you turn up the temperature?

 

Yah I hear the the a/c running but u can tell it's blocked. It's only sometimes though. It sat overnight and worked find this morning. Going to have my mechanic hook up vag com tomorrow and see whatsup

 

The AC vent has some sort of actuator that controls the flaps. It is closed until the A/C temperature has reached the desired level.

 

Has worked fine ever since. I'm not sure what caused the two glitches.

 

Certain electrical systems are prevented from working when the battery charge is low, maybe it was that.
