Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.
