Start by unplugging the wires. There will be two wires of positive and negative feed. They should be putting out around 12 volts of direct current. Use a voltmeter to check that there is current present. If there is not, you need to check both the wires and the fan relay to see if replacement is required. The fan relay will be under the hood.
