Commander 4WD V8-4.7L VIN N (2006)
Power Door Lock Switch: Description and Operation
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.
The driver side window/lock switch combines a power lock switch, a driver power window switch with an Auto-down and Auto-up feature, master
switches for each passenger door power window, a power window lockout switch, a power mirror selector switch, and four power mirror adjustment
switches in a single assembly. The switches in the window/lock switch can be diagnosed using conventional diagnostic tools and methods.
Power Lock Switch
The power lock switch circuitry is connected in series between ground and the driver door switch mux input of the instrument cluster (without memory).
If equipped with the memory system, the circuitry is connected to the memory mirror module. Each power lock switch position (Lock, Unlock, and
Neutral) provides a different resistance value to the instrument cluster or memory mirror input, which allows the instrument cluster or memory module to
sense the switch position. Based upon the power lock switch input, the instrument cluster or memory module controls the battery and ground feed outputs
to the individual power lock motors to lock or unlock the door latches. The Light- Emitting Diode (LED) in the power lock switch is connected to battery
current through the power window circuit breaker in the Integrated Power Module (IPM) on a fused ignition switch output (run-acc) circuit so that the
switch will be illuminated whenever the ignition switch is in the On or Accessory positions.
Power Window Switches
The power window switch circuitry is connected to battery current through a circuit breaker in the Integrated Power Module (IPM) on a fused ignition
switch output (run-acc) circuit so that the power windows will operate whenever the ignition switch is in the On or Accessory positions. Each two-way,
momentary master passenger power window switch in the window/lock switch provides battery current and ground to the individual power window
switches on each passenger door so that the power window switch controls the battery current and ground feeds to its respective power window motor.
The switch for the front driver and passenger window include an auto-up/down feature. When both front control switches from the driver or the front
passenger window switch is actuated to the second up/down detent the DDM/PDM drives the window to the full up/down position. For passenger control
from the master window switch a CAN message is sent from the DDM to the PDM. The Auto-up/down event is cancelled by actuating the paddle either
