Passenger Window-Down Input Signal

The voltage from the Power Window Relay R22 is applied through terminal X1-8 of the Passenger Window DOWN switch contacts to body control module (BCM) terminal X4-12, via circuit 167. This voltage then passes through the BCM relay's normally closed contacts to BCM terminal X4-13 to the window motor terminal X1-A via circuit 667. Terminal X1-B of the window motor is connected to ground via circuit 666 and switch terminals X1-7 via the UP switch contacts to ground via terminal X1-9 and circuit 650. NOTE: The power window motors each contain an internal overload thermal breaker which is activated (opens) if the power window switch is held in the UP or DOWN position for more than 20 seconds. This prevents overheating of the power window motor windings. After a cool down time of approximately 40 seconds, the thermal breaker closes again and allows normal motor operation.
