Rear Window

The Rear Window Switches are tied in a series circuit to the Console Window Switch. At rest, each switch contact is tied to ground through the Console Window Switch. When the master switch is operating a rear window, battery voltage is applied to one side of the associated Rear Power Window Motor. The motor drives the window in the corresponding direction.

When a Rear Window Switch is operated, battery voltage is applied to the Rear Power Window Motor through CKT 1307. The motor drives the window in the corresponding direction.

Each motor is protected by a built-in electronic circuit breaker PTC. If a Window Switch is held too long with the window obstructed or after the window is fully up or down, the PTC resistance increases. The resistance returns to normal after voltage is removed from the motor terminals.
