@$#%! RATS!
I Found a chewed wire in the aux fan circuit.
I found the Relay in #2 position from left to right of the three rows of relays as viewed from the front of the car, row nearest front. Part #001 542 02 19
Do wires taste good to vermin? I've had this car stored at my ranch for a few months. I'd been better off loaning it out to the homeless.
