Benzmac,
Thanks for the reply. I did bridge the wires on the red switch on the drier this weekend and the fan came on like clockwork. Trouble is, with the exception of that moment, I have never heard the aux fan kick in...period. Of course, that might have something to do with the blown fuse that I replaced. Heh.

How long after turning on the A/C should the aux fan engage? Driving the car with A/C on for 10-15 minutes did not cause the aux fan to engage, even with engine temps in the 90-100C range.

Thanks very much,
