Always check fuses first. They are cheap and easy. Next, with a jumper wire, run power directly from the battery to the fan motor to see if it is good. If it doesn't work with direct power, replace the motor. If it does, then check the fan relay in the relay block. Make sure there is power to the relay and switch it with another relay with the same part number. After that, check the temp switch. If it is good, either there is a broken wire in the circuit or the PCM may have a problem.
