So i went to the track wed night and on my way home i realized that my ac wasnt coming out of my vents..... No matter what setting i put it on it only comes out of the defroster..... I am assuming it has something to do with a hose or something, anybody have any clue?? Thanks guys.

 

Check THIS check valve, and check THIS vacum tank...

I checked the first one and its fine, i have to wait till daylight tomorrow to check the one under the car... What am i looking for, a hose disconnected..... Or what?

 

Yea a hose disconnected. Or a crack in those hoses somewhere!

 

The check valve on my car, used to break religiously. I have had the best luck actually reusing a cracked one, just putting some GOOP on it. It has wroked great since and as long as its been on there I probably would have gone through 3 new ones, haha. Another thing that helps is getting it as far away from the manifold as possible, I also wrapped mine in metal tape to help reflect the heat. Working great so far. Check that valve real good, just the tiniest crack is all it takes. Good luck to you.
