Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** only reason why this many compressors would have seized would be if the system was not flushed correctly. If they had flushed the system and this still occurs then the vehicle more than likely needs a new condenser. Debris gets stuck in the condenser and over time pieces come out causing the compressor to fail. I hope this helps. Please let me know if you need anything else.
They must be assuming that if it is an exterior failure then there is no reason to flush the system. It is possible that there is an alignment issue with the compressor or that the belt tensioner is too tight, but the system needs to be flushed. Just a small amount of contamination will cause this also.
