Power Window Motor: Notes

Connect the UP switch to fully close the window glass, and continue to press the switch for 10 seconds. See Fig 1 .
At the moment that the UP switch is released, press the DOWN switch. The circuit breaker can be considered good at this time if the door window glass begins to open within 60 seconds.
