Paging Bastien, PM is Full

Paging Bastien, PM is Full I tried to answer your PM, but it says there is no room. To answer the question about the AC only blowing out the defroster, the vacuum source for the AC and heat control is at the rear of the intake near the MAP sensor. It can come unplugged, the plastic hose can come out of the rubber connector or the plastic hose can crack. If there are no leaks then it could be an AC head unit issue, but that is very rare. Hope this helps.

I checked all the vacuum hoses and they're all plugged. I hope it's not my AC unit. It shouldn't be, It blows cold air and I can see condensation on the unit.

The AC head unit in the car is what uses the vacuum to actuate the doors. You can pull the head unit out and start the car to see if vacuum is making it to the head unit. If there is vacuum there, the there is something up with the controller. If there is no vacuum there, then the vacuum supply line is it somehwere between the head unit and the engine. The AC getting cold just means that the compressor, condensor, evaporator and freon lines are okay, just no control over the actuator doors in the dash to get the air to the proper ducting. Good luck.
