Crew Cab

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 of the Motor turns depends on the polarity of the supply voltage provided through the switch.

The LH Master Window Switch controls all of the Window Motors. Back window also has its own control switch.

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 or ACC, battery voltage is supplied to the LH Master Window Switch and Window Lockout Switch through CKT 343.

When any of the UP Switches are operated, battery voltage is supplied to the Window Motor and is grounded through the DN contact. The Motor runs to window up. When any of the DN Switches are battery voltage is supplied to the Window Motor in the opposite direction. The Window Motor is grounded through the UP contact. The Motor runs to drive the window down.
