Checking to see if anyone might have a a/c wiring diagram that will work on my 78 1/2 ton 4wd. If you know where I can locate or if you have one please help.

Re: I am needing a/c wiring diagram 78 k 1/2 ton
Is there a part specific you're looking for or just the whole thing? If the whole thing you can get repros or factory style off ebay from time to time.

Re: I am needing a/c wiring diagram 78 k 1/2 ton
Thanks, I am having trouble with my A/C blowing fuses on high only. I havent had the truck long, so I am not for sure some hack hasnt been working on it before me. I have put a new relay, new resistor but that hasnt helped.

I'm curious if the blower motor may be going bad as well.

I can wire the fan direct and it seems to work fine.

Sounds like the switch in the panel I would think maybe?

Re: I am needing a/c wiring diagram 78 k 1/2 ton
Changed out switch in dash, blower motor, speed resistor and relay. This still did not fix it. It now blows cold Just cant put it on high. Guess I will have to settle for this now. Thanks for your help.
