Question about Cars & Trucks
The fan is easier to test, it's only 2 wires. Power and ground, easy test. Check the pigtail ( connector ) for corrosion.. To test resistor you'll need a voltmeter to test wires at fan. Fan only knows on and off. The resistor changes ground for other speeds. You could just try tapping on motor to see if it spins if it does change it
