Elantra GLS Wagon L4-2.0L (2000)
Power Window Switch: Description and Operation
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 the right front power window cannot 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 contacts of the power window relay at all times. The coil of the relay is supplied battery voltage when the ignition switch
is ON position. Battery voltage is then supplied to 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 drive the window.
Window Switch Operation
With the power window relay energized, battery voltage is also supplied to the passenger window switches as long as the lock switch in the power
window main switch is OFF (not depressed). When the passenger windows switch is operated, battery voltage is applied to one terminal of the power
window motor and 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.
