Hi Guys:

All of a sudden my 2000 Ford Taurus, mileage appx 48,000, V6 has a problem. It started when the right passenger side vent started making a chirping noise.

Then the fan switch did not work any more, except in position # 4. So we can only get a high volume of cold air through the air conditiong vent. Any suggestions?

Thanks,

I would say that the reostat (spelling) on the switch is at fault and since 4 is high and passes voltage straight through it still works. Replace.

Suggested Repair

Replace the blower fan switch. The rheostat is likely failed; high (position 4) still works because it passes voltage straight through.

Conversation Summary

A 2000 Ford Taurus began chirping from the passenger vent, then the blower worked only in position 4 (high). The expert said the switch rheostat is at fault because high speed bypasses it, and recommended replacing the switch. The owner thanked the responders.
