Door Lock And Power Window Circuit Breaker And Relays Locations
To test the circuit breaker, connect the negative lead of a voltmeter to a known good ground, and touch the positive lead to one terminal of the circuit
breaker. If battery voltage is present, test the other terminal of the circuit breaker. If battery voltage is present on only one terminal, then the circuit
breaker is defective. If battery voltage is present on neither terminal, check for a burned fusible link or power lead wire to the circuit breaker.
