GENERAL INFORMATION
INTRODUCTION
Power windows are available as factory-installed
optional equipment on this model. The power lock
system and power mirror system are included on
vehicles equipped with the power window option.
Refer to 8W-60 - Power Windows in Group 8W - Wir-
ing Diagrams for complete circuit descriptions and
diagrams.
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 raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. Additionally, a set of master switches on
the driver side front door trim panel allows the
driver to raise or lower each of the passenger door
windows. A power window lockout switch on the
driver side front door trim panel can prevent the pas-
senger door windows from being operated, except
from the master switches. The power window system
receives battery current through a circuit breaker in
the junction block, only when the ignition switch is
in the On or Accessory positions.
The power window system includes the power win-
dow switches on each door trim panel, the circuit
breaker in the junction block, and the power window
motors inside each door. 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
the owner’s manual in the vehicle glove box for more
information on the features, use and operation of the
power window system.
DESCRIPTION AND OPERATION
POWER WINDOW SWITCH
The individual power windows are controlled by a
two-way momentary switch mounted on the trim
panel of the passenger side front door trim panel
and, on four-door models, on each of the rear door
trim panels. Two-way momentary master switches on
the driver side front door trim panel control all of the
power windows in the vehicle. The driver side front
door trim panel also has a two-position power win-
dow lockout switch.
The front door power window switches and the
power window lockout switch are integral to the
Driver Door Module (DDM) or Passenger Door Mod-
ule (PDM), respectively. The rear door power window
switches are stand-alone units.
Each power window switch controls its power win-
dow motor by switching battery current and ground
