I need a wiring diagram for the ac controller in a 1991 chevy Cheyenne c1500 305 5 speed long wheel base pickup truck. The one in Haynes is not right and my problem is that a while ago my ac controller stopped working so I pulled it out and straight wired the 12 volt to my fuse box. Now every time I turn my truck on I have to turn my ac on it has no memory and that is the wire im trying to find now as I will throw it over on the constant volt on my aftermarket radio. I could not find where the wires were burnt at and is why Im doing it this way.



Plus ive exhausted good to no ends and hoping someone has a factory book a can share an image with me.


Haynes book says its a tan wire that is the 5 v constant but it was not.

Dude.. Google 1991 Chevrolet Cheyenne wiring diagram

I read your post like 5 times and still can't figure out what the shit your saying.

Go back to school then as your comprehension skills are that beneath a kindergartener.

I could sit here and explain to you why my comprehension skills are above and beyond exceptional, but instead i will yield to you..

Good luck in figuring out whats wrong with your 23 year old chevy.

Oh, and the Haynes manual isn't wrong, lol.

heh, the Haynes Manuel doesn't even get the color right on the wires.
