Passenger Windows
The passenger window switches are tied in a series circuit to the left front power window switch. At rest, each switch contact is tied to ground through the left front power window switch. When the master switch operates 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 CKT 1307. The motor drives the window in the corresponding direction.
The lockout switch, which is incorporated in the left front power window switch, controls the voltage on CKT 1307. When the lockout switch is engaged, battery voltage to CKT 1307 and the passenger window switches is interrupted. This function allows driver control when the passenger window switches are operational.
Each motor is protected by a built-in electronic circuit breaker (PTC). The PTC resistance increases under the following conditions:
^ If a window switch is held too long with the window obstructed
^ After the window is fully up
^ After the window is fully down
The resistance returns to normal after the voltage is removed from the motor terminals.
