The compressor itself maybe going bad. From what I understand the seals inside the compressor go bad over time.

1 out of 1 people think this is helpful.

Yah the bearings themselves within the unit. When the compressor clutch is not engaged the pully spins freely on the clutch bearings, when the clutch engages it would then rotate the compressor shaft. I would change or replace soon you don't want the compressor to sieze..


My '93 Caprice did that for years. Never changed the compressor and the A/C always worked fine. The guy I sold the car to has had no A/C issues either. If it works, don't fix it. HTH. -Jim


Sometimes you can get away with it, but if it is the bearings and they do sieze you have a 50/50 shot of blowing the clutch or breaking the belt.
