Why does my compressor make a noise like dadadadadadadad…it works fine but makes the noise
94 gmc 2500
There are several sources that could make that noise.
- Bearings on idler pulley are failing
- Compressor bearings failing
- A/C clutch bearings failing. You could give it a short squirt of WD-40 around the clutch bearings and see if the noise changes. If yes, that could be the source of the noise. Don’t get it on the belt.
Thank you Sir
