You can check the fan motor another way. Connect the fan motor directly to the battery. It should work. If not then replace the motor.

Yeah, my brother told me that I could do these things to find out but we don't have a multimeter and I'm hesitant about doing something like connecting the fan motor to the battery myself...

Any idea on how much it would cost to fix any three of these things (motor, sensor, relay) at a dealership?


Also, is the check engine light supposed to turn on if any of those three things (fan motor, sensor, relay) wasn't working because my check engine light has never turned on?
