Circuit Breaker

  1. Locate circuit breaker for power window system. See TROUBLE SHOOTING  . Pull circuit breaker out slightly, but ensure circuit breaker terminals still contact terminals in fuse block.
  2. Connect voltmeter negative lead to ground. Using voltmeter positive lead, check both terminals of circuit breaker for battery voltage. If voltmeter indicates battery voltage at both terminals, circuit breaker is okay.
  3. If voltmeter indicates battery voltage at one terminal only, replace faulty circuit breaker. If voltmeter indicates no voltage at either terminal, check for an open or shorted circuit to circuit breaker. Repair circuit as necessary and recheck system operation.
