2000 Ford Taurus Repair Question
2000 Ford Taurus cooling fan
2000 Ford Taurus 6 cyl Front Wheel Drive Automatic 108000 miles
cooling fan only work with ac on,and it in high speed
This is good this indicated that the fan and the circuits are working. If I am understanding you right the fan doesn't come on at temp but works with the a/c on or the defrost. So you probably have a bad fan temp control switch. Hope this helps and thanks.
