Circuit Description A permanent magnet motor operates each of the power windows. Each motor raises or lowers the glass when voltage is supplied to it. The direction the motor turns depends on the polarity of the supply voltage. The power window main switch controls all the power window motors. Each window switch controls only one of the power window motors. If the lock switch is depressed, the rear power windows and right front power window can not be controlled by their own window switches, but they can still be controlled from the power window main switch. Power Window Main Switch Operation Battery voltage is applied to the coil and the contacts of the power window relay at all times. The coil of the relay is grounded through ETACM anytime the ignition switch is ON. Battery voltage is then supplied to the power window main switch through the closed relay contacts. | When any of the switches in the power window main switch are operated, battery voltage is applied to the power window motor. The power window motor is grounded through the opposite contact in the power window main switch. The power window motor runs to dirve the window. Window Switch Operation With the power window relay energized, battery voltage is supplied to the passenger window switches as long as the lock switch in the power outside mirror switch is in unlock position (not depressed). When the passenger windows switch is operated, battery voltage is applied to one terminal of the power window motor. The other terminal is grounded through the opposite contact in the window switch and the main switch. The power window motor runs to drive the window. |
