Passenger Windows

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

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

Voltage on circuit 1307 is controlled by the Lockout Switch incorporated in the LF Power Window Switch. With the Lockout switch engaged, battery voltage to circuit 1307 and the Passenger Window Switches is interrupted. This allows the driver control when the Passenger Window Switches are operational.

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.
