    My aux fan has stopped working. I did the usual check by disconnecting the fan connector and applying 0 & 12V to the fan on all 3 pins. The fan doesn't start so I'm guessing the fan is dud.

    I then thought I would just check the mating half of the connector to check the correct signals are getting to the fan in the first place. I shorted pins 2 & 3 on the temp sensor and sure enough I could hear the correct relay clicking but there was no voltage on the connector. Tried pins 2 & 1 and the same thing - no voltage. Tried the air con and again no voltage. I did a continuity check between the chassis and the gnd pin on the connector and they are not connected. I did the whole test again measuring the voltage between the chassis and the 3 power pins and again nothing!

    Does anybody know if there is an in-line connector somewhere between the aux fan relays and the aux fan connector?

    Pritts.
