95 HVAC controler
Does anyone have a schematic for the control board on a 95 HVAC controller? I thing I have a solenoid that's not working. I fixed the vacuum connections and have it set on the dash vents for now but I would like to repair the controller and get it working properly.

I made a schematic of the controller in my car. I know they eliminated some of the solenoids in later years and I believe major changes were made right at the end of C4 production. Maybe this will be helpful:

But I think what you are really asking for is the schematic for the HVAC programmer. (Not control head)
Perhaps you can get a defective programmer and use it for parts.

I have a manual for a 96' and the wiring diagram is spread over multiple drawings each assigned to the different functions. There are 5-6 just for the C68 Electronic Controls. What section are you needing? There are ones for Blower Control, Power-Communication-A/C Clutch Control, Air Delivery and Vacuum Distribution, and Temperature Control

See if these will help. Not from the FSM but are GM documents.
*I see I posted second but I will leave them up anyway for they may sill be of use.
Jim, did you get your temperature sensor figured out from other post?
