i have a 94 gt and today the it deceided that all of the air settings = floor and defroster. If I turn it to AC or MAX AC its cold but it doesnt blow through the vents only the defroster ad floor. Any ideas what i need to do to fix this?

There's a vacuum line that runs from a vacuum tree on the driver's side fender, across behind the intake, and over to the passenger side (don't remember exactly where). It is broken, fix it, and your A/C will work again. Oh and it's real skinny, and it's probably wrapped in some insulating wrap.

Also, if like a fox, there is a vac box under the dash. If a line comes off, etc, similar symptoms.

Good luck.

IIRC it's way back in the rear driver's side corner of the engine bay (where the vacuum tree is), and it runs across the engine bay horizontally to the entry place in the firewall.

When mine broke I went to Autozone and spent $5 to get a non-skinny normal vacuum line to replace it, and secured it in the engine bay with some electrical tape. Works the same as the old one, and my A/C is exactly like before.
