Compressor comes on but not the condenser fan. Pulled the relay and jumped it out. Still no 12 volts at the fan plug. Is there a fan cycling switch ? Must be. Anyone know where it's located or what it looks like ? Or what else may be keeping the fan off ? Thanks !!!
Did you find the fuse yet? Do you have 12 volts to the relay? If the fan motor has seized, the fuse will blow.
Often on a late-model vehicle, the computer reads a high side pressure sensor and controls the fan relay.
