Rear Window

The rear Window Switches are tied in a series circuit to the Master Window Switch. At rest, each switch contact is tied to ground through the Master Window Switch. When the Master Window 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 the 1307 circuit. 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.
