Check the actuators in your heater, they control air temp as well as direction. The temp one may be stuck or not working. It can be vacuum or electric. I'll send a generic pic along

I had this happen to me. 2002 Linc Cont: Try to raise the temperature to max (90) as if turner on the heater. This actuates the something, something. Lower the temp back to cool the car; the a/c should work if system is charged. This has happened a couple times to me - it corrected the problem. Good Luck. Jack

When you move the vent selector does it change where the air comes from? When you move either of the selectors, can you hear parts moving inside the airbox?

YOU ROCK! This worked for me! THANK YOU. Saved me a diagnostic charge at the least. Sent it up to 90 top setting for about 1 min, dropped it down and boom kicked in! Thanks again!
