Driver Side Switch Operation

Circuit F21 supplies voltage to the right power window switches for raising and lowering the windows. When the drivers side switch 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.
