Description
DESCRIPTION
A window/lock switch located in each front door trim panel. The driver's side window/lock switch includes the following:
-
Power Lock Switch - A two-way, momentary, resistor multiplexed switch to control the power lock system.
-
Power Window Lockout Switch - A two-way, latching, push-button switch allows the vehicle operator to lock out the power window switches
on each passenger door so that the passenger door power windows may be operated only from the master switches.
-
Power Window Switches - A two-way, momentary power window switch for the driver side front door also has a second detent in the Down
direction and internal circuitry to provide an Auto-Down feature for the driver side front door power window. Another detent for the window up
on both front window control switches in the master window switch and the front passenger switch activates the express up window feature for
both front driver and passenger windows. The Driver Door Module (DDM) and Passenger Door Module (PDM) must be calibrated before this
feature is enables. The window is calibrated at the factory. If a re-calibration is required stall the window in the full closed position for greater than
500 milliseconds. In addition to the power window switch for its own door, the window/lock switch houses individual master switches for each
passenger door power window.
The passenger side window/lock switch includes the following:
-
Power Lock Switch - A two-way, momentary, resistor multiplexed switch to control the power lock system.
-
Power Window Switch - A two-way, momentary power window switch for the passenger side front door.
