Driver Window-Up Input Signal

By lifting and holding up the Driver Window UP button, battery voltage from the Power Window Relay is applied to the drivers window motor through switch terminal X1-12 and circuit 164. Circuit 165 is connected to ground through body control module (BCM) terminal X4-25, terminal X4-26, circuit 1136, the DOWN power window switch contacts and circuit 650. The lifting of the Driver Window UP switch causes the motor armature to rotate and raise the window while the button remains lifted. PASSENGER WINDOW-UP INPUT SIGNAL: By lifting and holding up the Passenger's Window UP button, battery voltage is applied to through the center console switch terminal X1-7 and circuit 666 to window motor terminal X1-B. Circuit 667 is connected to ground through BCM terminal X4-13, terminal X4-12, circuit 167 and the DOWN switch contact via X1-9 to circuit 650. This causes the motor armature to rotate and raise the window while the Passenger Window UP button remains raised.

The body control module (BCM) monitors the state of the Driver Window UP and Driver Window DOWN switches at X4-15 and X4-26 respectively. When the Automatic Window DOWN feature is in progress, if the Passenger Window UP switch is operated for any length of time, the window stops immediately as the motor is immediately presented with battery voltage across both terminals. The BCM senses this switch voltage on X4-15, and de-energizes the relay to permit the polarity across the motor to change and for the window to commence winding upwards. NOTE: If the Driver Window DOWN switch is pressed while Auto Window DOWN feature is in progress, the BCM senses this request at X4-26, but will not de-energize the relay until the Driver Window DOWN switch is released.
