This group covers diagnosis and service of only th e electrical components in the power window system. For servic e of mechanical components, such as the regulator, lift plate, window tracks, or glass refer to Group 23 - Body. Fol lowing are general descript i on s of the majo r components in the power window system. Refer to 8W-60 - P ower Windows in Group 8W - Wiring Dia- grams for complete circuit descriptions and diagrams. Refer t o the owner’ s manua l for more informa tion 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 req uir ed and feasible, the RHD versions of affected vehicle components have been construct ed as mir ror -image of the LHD ver sions. While mos t of the illustrations used in thi s gro up represent only the LHD version, the diagnostic and service pr ocedures outlined can generall y be appl ied to ei ther version . Except ions to this rule have been cle ar ly identi fi ed as LHD or RHD, if a special illustration or procedure is required. POWER W INDOW SYSTE M The power window system allo ws 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 clo se any of th e door windows. In additio n, a lockout swi tch on the driver side front door trim panel a l lows t he driver to disable all of the passenger door window switches. The power window system includes th e door mod- ules mounted in each front door, the switches mounted on the rear doors, an d the power window motors mounted to the window regulator in eac h door. In addition, several features and functio ns of the power window system a re made possible bec ause 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 allo ws 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 swi tch 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 controll ed by a two-way momentary switch mounted on t he t rim pa nel of each passenger door, and four two-w ay momentary 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. Z G POWER WINDOW SYSTEMS 8S - 1

DESCRIPTION AND OPERATION
POWER WINDOW SWITCH
The power windows are controlled by a two-way
momentary switch mounted on t he t rim pa nel of each
p a ss en ge r d oor, a n d fou r t wo-w ay m om en t a r y
switches on the driver side front door trim panel. The
driver side front door trim panel also has a two-posi-
t h r o u gh t h e s e s a m e t wo c on n e ct i on s wil l c a u s e t h e
motor to r otate in the opposite direction.
In addition, each power window motor is equipped
with an integral self-resetting circuit breaker to pro-

motor and gearbox assembly cannot be repaired and,
if faulty or damaged, the entire motor assembly mu stbe replaced.

DIAGNOSIS AND TESTING
POWER W INDOW SYSTEM
NOTE: The following tests may not prove conclu-sive in the diagnosis of this component. The most
reliable, efficient, and accurate means to diagnosethis system involves the use of a DRB scan tooland the proper Body Diagnostic Procedures man-ual.
Remember, the DDM circuitry controls the output
t o t h e d r iver s id e fr on t a n d r ea r p ow er w in d ow
motors. The PDM circuitry controls the output to the
passenger side front and rear power window motors.
