I have replaced my AC compressor three times within the past six months. Thinking it is an electrical issue. Had to hot-wire to turn on. I do not not keep the AC on all the time. I understand that hot-wiring is a temporary fix. However, can still not determine why power is loss from compressor to fuse box and switch.

This is auto temperature control on this car and must be scanned to find any problems with sensors or switches because you set the temperature the A/C will run constantly to keep the temp correct until below freezing. If clutch is burning out there is no need to replace compressor unless there is junk in system from the very first compressor failure which would require the system to be back flushed to get all the junk out of it.

Thank you for the quick response and information. I will let my buddy know about and we will dive deeper. He did do a basic voltage light test to determine power is reaching fuse box. But it does not make back without having to add a hot-wire at at temperature sensor.
Thanks again.
