A/C compressor on my 99 silverado 1500 4WD 5.3 litre question. The compressor works fine, the pressures are good, I've bypassed the hi and low pressure cut out switches, no problems there. The clutch seems to be the problem. I'm suspecting a weak electromagnetic coil problem. Can the relay be an intermittent problem like this? It runs fine for 20-30 minutes, then it stops going down the highway when having to change my speed at times. Is it a weak clutch? I have never seen a discussion anywhere on this subject. I am a licensed in residential ac in Texas. I just don't do clutches on cars. Also what's the best procedure to replace the clutch and bearing?
Thank you in advance,
Tex
