1993 Buick LeSabre Custom 3.8L a/c vents VIN: 1G4HP53L6P
Thanks to those who responded, but this one wasn't a vacumn issue. Turns out the controller grounds the wires to each vacumn solenoid in order to make it switch. The pink wire (A/C - Defrost demand) wasn't the circuit affected. According to the wire diagram on...

1994 Oldsmobile 98 Regency Elite 3.8L Surge VIN: 1G3CW5218R
