    1990 ZR-1 air conditioning electrical

    I have had a failure of the a/c system on my 1990 ZR-1. By not driving it regularly all the freon has leaked out. My mechanic has put in new freon and has been able to get the compressor to work, but cannot find the electrical problem to get to work as it should using the temperature controls.

    I was wondering if someone might have had a similiar problem to this and how to check things out. He has the wiring diagram for a regular 1990 Vette, but says one wire is different. It is puzzling to him and me.

    I was wondering if anybody might have a wiring diagram for a 1990 ZR1 or any advice.

    Thanks! Jim

    James I checked and see you are in KY. Just east of I65 in TN Gordon Killerbrew resides. At one time he gave classes on how C4's function. He has a web site and you can call him to obtain what you need to do. There is a fee for the call. He retired from the factory that built your ZR1.
