Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Rear Passenger Power Window/Switch Operation
The rear passenger power window switches receive battery voltage through the power window master switch lockout signal circuit when the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through the normally closed up and down contacts of both rear passenger power window switches and the main power window switch. When either rear passenger power window switch is placed in the down position, the power window motor down control circuit is switched to 12 volts which is applied to the down side of the rear passenger power window motor. Since the other side of the rear passenger power window motor is connected to ground through the normally closed up contacts of both the rear passenger and main power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the main power window switches.
