I just found a new problem on my truck.... When the truck is at idle the AC runs fine. When I accellerate or get on the gas the AC starts coming out of the heater vents by the windsheild. Any ideas?? Help please

 

you have a vacumn leak, i think there has been some threads on this issue already that might tell you were to begin looking. i had the exact same problem with my 93 thunderbird, turns out that somehow a vacumn line behind the glove box became disconnected and when i hooked it back up my ac worked perfect again

 

Searched for it and found the problem... Taking it to the shop on MONDAY... Thanks
