I have a 1995 pontiac grand prix se with some a/c problems. I have a haynes manual, but it has 16 wires labeled coming out of my hvac control unit; I have 20 wires. My selector switch is stuck on bi level defrost... and the switch is built into the control panel. does anyone have a wiring diagram for a 95 grand prix with manual temp control and a 3100 v6 engine? (prefer something not outta a Haynes book) Thank you

Jeremy

check under the hood for a vacuum leak

usually when the ducts are stuck on defrost, it is a vacuum leak. There should be a black, hard, plastic tube that goes into the wiring harness, that goes into the car on the passenger side.
