I just came back from a trip to town. I restarted the car 4 times and the fan came on every time. yesterday the fan worked every time (twice). These are all occurances where the ignition was turned on (not just turn ignition to accessory as when i tested before). Needless to say i'm starting to be very happy with ver 435.

Loren,
If your fan has never worked, then i suggest the wiring is not correctly installed.
