To test the left front down and express down switch position, connect pin 4 to ground and pin 12 to a 12 volt source. Using a voltmeter, measure for voltage from pin 13 to ground.

To test the right front down and express down switch position, connect pin 4 to ground and pin 12 to a 12 volt source. Using a voltmeter, measure for voltage from pin 3 to ground. If the correct results are not obtained, replace the switch.
