is there any way to test my electric fan motor to see if it is spinning at full capacity? it looks and sound slow and not staying cool in general. i have checked all related cooling system parts and they seem fine, but this has me stumped.

 

Check the resistanve from 1 terminal to the other and see if you can compare that to one of anyone else's that worked for sure. Mine is from a 93 grand am so i dont want to throw numbers out there.

 

My fans read 7 to 200 ohms through the wiring from the relay. Turns out I had a burned plug in the harness and I removed it butt spliced the wires with weathertight connectors. It now reads .3 to .7 ohms and flickers open when I spin the fan. This can't be good but they are working. And both fans read the same. I had a spare set of fans laying around from a parts car I bought and they were both reading open so they must be junk.
