How often should I expect to replace my air-conditioning compressor?
Air-conditioning compressors often last the life of a vehicle, but they can fail because bearings wear out, seals leak and long-term corrosion takes its toll, plus other factors. If a compressor does need to be replaced, it should be a one-and-done fix, not something that occurs every 50,000 miles. Frequent compressor failure is probably caused by a misaligned accessory drive belt, a faulty pulley or another issue creating undue stress
