Whats wrong with my a/c?
Whats wrong with my a/c? Its blowing ice cold air on the feet, but won't blow anything out the dash vents. The only thing that has changed on the car recently is the underdrive pulley was put on. Since its blowing ice cold on the feet, I really don't think the compressor is going out.
Would the UD pulley have affected it that drastically? Maybe a vaccuum leak somewhere? Any suggestions are appreciated.

You'll see some pics of the manifold in those pics. There's a little (approx. 1/4" OD) fitting coming off the back, pointing toward the big plastic a/c box/plenum thing. That vacuum line controlls the "trap door" which is what makes the pshhh sound when you turn the selector **** in the dash.
Trace that vacuum line untill you find the leak. It goes to part of the AIR system, a couple of T fittings, to a vacuum canister, to the a/c system etc. The line runs inside the wireloom crap that is on the passenger side fender.
