Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit Operation
A Permanent Magnet (PM) 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 switches control the supply voltage polarity.
The master door lock/power window switch assembly controls both of the motors. The right hand window switch controls only the right hand window motor.
Each motor is protected by a built in circuit breaker. If a window switch is held too long with the window obstructed or after the window is fully up or down, the circuit breaker opens the circuit. The circuit breaker resets automatically as it cools.
When the ignition switch is in RUN position, battery voltage is supplied to the master door lock/power window switch assembly, the PWR WDO circuit breaker, and the PNK wires. See WIRING DIAGRAMS . When any of the UP switches are operated, battery voltage is supplied to the window motor through the DK BLU wire. The window motor is grounded through the down contact. The motor runs to drive the window up. When any of the down switches are operated, battery voltage is supplied to the window motor in the opposite direction through the BRN wire. The window motor is grounded through the UP contact. The motor runs to drive the window down.
