I have a '99 Silverado with 168,000 on her. The a/c belt broke about
15,000 miles ago.... had a new one put on... it broke after 8,000 miles...
had a new tensioner and belt put on... so far so good as far as breakage.
The problem now is that it seems to work, blowing cold a/c in the morning usually, but it cuts out sometimes and just blows warm air.
I've noticed on the freeway sometimes, if I stomp on the peddle,
it will start blowing cold air again. This also happens while stopped.... if I accelerate fairly quickly, it starts blowing cold air. Does this sound like some sort of switch problem, clutch or what? Thanks for your help!
