Maintenance/Repairs

About 5 years ago, my air conditioner started making a metallic-sounding grinding noise, when it is turned OFF. This noise goes away if the A/C is on. My mechanic said some part was slightly bent, bent it back, and this fixed it for a while. Eventually the noise came back but was intermittent. I drove the car for years hoping it would go away, leaving the A/C on most of the time. The noise is no longer intermittent, and my new mechanic says that it seems louder than before and if I don’t get it fixed, it might cause the car to stall out. He offered to bypass it with a belt or replace the unit. Any thoughts on what this could be? I drive with the A/C on now.
