I don't think its the resistor as Summers said that controls the fan speed. Butt I believe you can check it by using a Volt Ohm meter and checking the different poles for different resistance. If you have an electronic controlled system then it doesn't have a resistor you can check its done electronically inside the controls.

I find a warm fart on a cold windshield on a cold day goes a long way!
