Dakota Quad Cab 2WD V8-5.9L VIN Z LDC (2002)
Power Window Switch: Description and Operation
On conventional cab and club cab models, the power windows are controlled by two-way switches integral to the power window and lock switch bezel
on the passenger side and the Driver Door Module on the driver side of the trim panel of each front door. A second power window switch in the driver
side switch and bezel unit allows the driver to control the passenger side window. On quad cab models, the power windows are controlled by four
two-way switches and a power window lockout switch that are integral to the Driver Door Module on the driver side front door trim panel. Additionally
each of the passenger doors has a single gang two-way power window switch mounted in a bezel on their respective door trim panels.
On all models, the power window switch for the driver side front door window has an Auto label on it. This switch has a second detent position beyond
the normal Down position that provides an automatic one-touch window down feature. This feature is controlled by an electronic circuit and a relay that
are integral to the driver side front door power window and lock switch unit.
The power window switches control the battery and ground feeds to the power window motors. All of the passenger door power window switches
receive their battery and ground feeds through the circuitry of the driver side master switch unit. On quad cab models, when the power window lockout
switch is in the Lock position, the battery feed for the individual passenger door power window switches is interrupted.
A Light-Emitting Diode (LED) in the paddle of each switch is illuminated whenever the ignition switch is in the ON position. However, on quad cab
models the LEDs for the passenger power window switches are extinguished whenever the driver selects the Lock position with the power window
lockout switch.
