What to Do When the Car Air Conditioning Compressor Seizes Up?

[VonAlex]

At this point, immediately turn off the compressor clutch power supply and check if there is any leakage in the system. If not, it may be an issue with the oil circuit. In this case, check if the oil pipe is crushed or twisted. If not, it should be caused by a clogged oil drain valve on the evaporator pressure control device, which then requires repairing the oil drain.
