    Where can I find a wiring diagram for my 75 Blazer's air conditioning/heater? I've tried all the Chilton and Haynes manuals.

    Thanks,

    Hey Ted, I've got a Haynes with schematics for later models....they seem very close to what is actually on my '74. Let me know specifically what you're looking for and I'll make a copy or scan this one. Email direct if ya want to.... parkerma@earthlink.net

    Michael,

    I think I need the diagram showing the wiring from the slide switch to the componets. I bought the truck a year ago and have replaced a lot of parts. It's finally running and my son is taking it to college next week. Almost everything works except the air cond. It works on max only. The compresser only comes on in the MAX & heater position. It should come on at MAX, Normal, Bi-Level & Defrost. I've gone to the library and they have detailed air cond diagrams but none for a 75. If yours shows the slide switch it might help.

    Thanks for your help,

    Ted
