I have a 92 5.0 lx...my ac works, but it only blows out by the window and on the floor. i replaced the switch and it did not fix a thing. another problem, every time i need my haynes manual, i cant find it, and when i dont, i see it everywhere....what is up with that lol.

one of the vcume line for the door blend motor is probally cracked. Start and the Hvac control head on the dash and follow the line back checking for cracks or broken lines

yeah, check all your vacume lines comming from the back of your hvac panel, the ones off of your control switch. one of them is broken or has come off. that'll fix her right up!

thanks guys, i traced some of the hoses through the firewall (or looked like they were headed that direction) and on the driver side just to the right (as you are facing it) was the cracked hose....i took a piece of hose to verify that was the problem, and the ac works great now.
