I have a 93 chevy silverado. Z 71 1500, 5.7L. Recently I turned on the defrost, and at idle the truck began to have a rough idle to the point of almost stalling. I looked under the hood, and when the a/c, or the defrost is engaged, and the a.C compressor is active, it malfunctions. The clutch on the front of the compressor works fine for the first few seconds, but then it engages and disengages continuously, causing my truck to idle very hard, and the a.C and defrost to be unworkable. What is my problem, and what can I do?
have the same problem?
