A/C issues - 1993 GMC Sierra

[apawk]

Hey guys,

New to this forum and had a question. I just purchased a 1993 GMC Sierra 1500 4.3 from my father. The A/C worked fine on it until U-Haul put a brake controller on for him. Since then it has not worked. I was wondering if any of you have and experience with this beyond checking fuses. The truck look fairly simple to work on with all the open area under hte dash and under the hood but i dont know where to start. Its 100 degrees here in Atlanta and need some AC !!! lol

Thanks again for any help!!

Check all the fuses and the relays to your A/C, start with that and also inspect your wire leads to your a/c compressor. Keep us posted and good luck, be gald to help you get your a/c working again soon.
