Hi all,
Important info first, I have a 1990 K1500 Silverado, 4wd, manual trans, 5.7 tbi. The previous owner put in a cam when he had the engine rebuilt, but otherwise pretty much stock so far.
The issue is- when I turn on my AC, the AC compressor doesn't stay engaged. You can hear it "click" on, it the pulley will engage for a couple seconds, then it disengages again. Then just repeats.
My thoughts are either the compressor clutch has gone bad, or one of the AC electrical components is going bad and sending an on/off/on/off signal.
I have the "fancy" digital climate controls, if that makes any difference.
Has anyone run into this? Know what the problem is? Want to guess? lol
I first noticed this about 3 weeks ago. Before that, the AC worked great and blew cold. It murdered my gas mileage, but it worked.
