GENERAL INFORMATION
INTRODUCTION
Power windows are standard factory-installed
equipment on this model. This group covers diagnosis
and service of only the electrical components in the
power window system. For service of mechanical
components, such as the regulator, lift plate, window
tracks, or glass refer to Group 23 - Body.
Following are general descriptions of the major
components in the power window system. Refer to
8W-60 - Power Windows in Group 8W - Wiring Dia-
grams for complete circuit descriptions and diagrams.
Refer to the owner's manual for more information on
the features and use of this system.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service procedures outlined can generally be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
POWER WINDOW SYSTEM
The power window system allows all of the door
windows to be opened or closed by operating a switch
on the trim panel for that door. The master switches
on the driver side front door trim panel can be oper-
ated to open or close any of the door windows. In
addition, a lockout switch on the driver side front

door trim panel allows the driver to disable all of the
passenger door window switches.
The power window system includes the door mod-
ules mounted in each front door, the switches
mounted on the rear doors, and the power window
motors mounted to the window regulator in each
door. In addition, several features and functions of
the power window system are made possible because
of the communication of the door modules on the
Chrysler Collision Detection (CCD) data bus network.
The power window system operates with battery
power supplied through a circuit breaker in the junc-
tion block, only when the ignition switch is in the On
position. However, a feature of this system will allow
the windows to be operated for up to thirty seconds
after the ignition switch is turned to the Off position,
or until a front door is opened, whichever occurs
first.
An auto-down feature allows the driver side front
door window to be lowered all the way, even if the
window switch is released. The driver side front door
window switch must be depressed in the down direc-
tion to a second detent to begin an auto-down event.
Depressing the switch again in any direction will
stop the window movement and cancel the auto-down
event.
DESCRIPTION AND OPERATION
POWER WINDOW SWITCH
The power windows are controlled by a two-way
momentary switch mounted on the trim panel of each
passenger door, and
switches on the driver side front door trim panel. The
driver side front door trim panel also has a two-posi-
tion power window lockout switch.
