Abnormal Noise From AC Compressor on GMC 1500 Pickup

Problem Description and Possible Solution

The air conditioning compressor may develop an abnormal noise and require replacement. We recommend that whenever an AC compressor is being replaced for a noise condition, a filter kit should be installed to prevent any metal particles in the system from damaging the new compressor.
