Can anyone tell me how to test the electric fan motor on a 1998 Ford Escort, 16v Zetec VCT?

If I unplug the motor, and put meter leads on the posts,
1. How should I have my meter set
2. What am I looking for on the meter
3. Would a continuity tester be a better test, if so, how to test with that
Thanks,
Gary

Does the fan never spin? Does it make a growling noise and move slowly?

If totally dead, it may be a blown fuse.

The fuse for the engine and exterior lights is usually under a panel inside the engine compartment, sometimes on the same side as the battery, sometimes on the opposite. May want to check it out as well.

If the fuse is blown, it may be the bearings of the fan are out. With power disconnected, make sure the blades spin freely. If you have your meter connected to the power jack in Volt mode, a some millivolts should show on the meter as well.

In the resistance mode, don't spin the fan at all, just make sure there is under about 25 ohms or so on the connector.
