When measuring resistance on your multimeter of the ceramic resistor, you want to make sure it is isolated from any voltages or other resistive loops it may be connected too as this will throw off your reading. I figured the easiest way to isolate it without using any tools was to disconnect the fan connector and fuses/relays associated to it before checking the resistance.
There is a fan circuit on the forum that have been posted by other members for reference.
