Power Window Switch: Description and Operation
Circuit Operation
CIRCUIT OPERATION
Driver Side Switch
Circuit F21 supplies voltage to the right power window switches for raising and lowering the windows. When the drivers side switch for the right
side window is put in the DOWN position, the switch supplies voltage to circuit Q26. Circuit Q26 connects to the down side of the passenger side
switch. Voltage passes through the passenger side switch to the window motor on circuit Q22. The ground path from the motor is on circuit Q12
back through the passenger side switch to circuit Q16, through the drivers side switch to ground on circuit Z1.
When the drivers side switch is put in the UP position, the switch supplies voltage to circuit Q16. Circuit Q16 connects to the up side of the
passenger side switch. Voltage passes through the passenger's side switch to the window motor on circuit Q12. The ground path from the motor is
on circuit Q22 back through the passenger's side switch to circuit Q26, through the drivers side switch to ground on circuit Z1.
Passenger Side Switch
Circuit F21 splices to supply voltage to the right window switch on the passenger side of the vehicle. When the passenger side switch is put in the
DOWN position, the switch supplies voltage to the motor on circuit Q22. The ground path from the motor is on circuit Q12 back through the
passenger side switch to circuit Q16, through the drivers side switch to ground on circuit Z1.
In the UP position, the passenger side switch supplies voltage to the window motor on circuit Q12. The ground path from the motor is on circuit
Q22 back through the passenger side switch to circuit Q26, through the drivers side switch to ground on circuit Z1.
