DESCRIPTION AND OPERATION
Glass, Frames and Mechanisms
Component Location
Windshield Glass
The windshield exterior mouldings are installed with the windshield glass. The windshield exterior
mouldings cannot be replaced without removal of the windshield.
Window Regulator Control Switch
Power windows are standard on all models. On coupe models, only the front door window glass can
be raised or lowered. The quarter window glass is fixed. On the convertible models, all four windows
can be raised or lowered. On all models, the window regulator control switches are available only to
the front seat passengers. There are no window regulator controls for the back seat passengers.
Quarter window glass operations are controlled by the driver window regulator control switch.
Window, One-
Touch Down
The LH window one- touch down feature is activated by momentarily pressing the driver window

regulator control switch to the down position. This allows the front door window glass to move
downward until it is fully lowered. Momentarily pressing the window regulator control switch while the
window glass is moving downward will stop the front door window glass.
Window Glass, Door
The bottom of the door window glass is mounted on a slider bracket which is part of the front door
window regulator. Door window glass bracket spacers provide attachment points for the door window
glass and prevent direct contact between the slider bracket and the door window glass.
Window Glass, Quarter
The rear quarter window glasses on convertible models are driven by a window regulator motor and
guide assembly.
Window Glass, Rear
On the coupe, the rear window upper garnish mouldings are installed with the rear window glass. The
rear window upper garnish mouldings cannot be replaced without removing the rear window glass. Klj . 2 ba

DIAGNOSIS AND TESTING
Glass, Frames and Mechanisms
Refer to Wiring Diagrams Cell
100 , Power Windows for schematic and connector information.
Refer to Wiring Diagrams Cell 56 , Rear Window Defrost for schematic and connector information.
Principles of Operation
Power Window Control
NOTE: Battery power and ground must be removed before disconnecting the GEM connectors to
avoid setting false DTCs.
The driver power window one- touch down operation is controlled by the generic electronic module
(GEM). This feature functions only when the ignition switch is in the RUN or ACCY positions. The GEM
determines ignition switch position by monitoring the key- in ignition, RUN/ACCY and RUN/START
circuits. The one-touch down operation is requested of the GEM by momentarily pressing the driver
window regulator control switch DOWN for 62 ms to 320 ms. The GEM uses the initial voltage input
from the down switch to begin the one- touch down operation. If the voltage input was less than 320
ms, the GEM will maintain the voltage supply to the motor down circuit. The GEM will maintain the
operation until:
zseven seconds expires.
z motor stall is detected by monitoring the current draw.
z a voltage input is received by the GEM on either the up or down switch circuits.
The ground for one- touch down operation does not pass through the GEM. The ground is supplied
through the driver window regulator control switch as with normal operation. If the GEM continues to
see voltage on the down circuit for more than 320 ms after initial activation the GEM will not effect
operation. The down circuit through the GEM is a direct connection to the motor in its normal state.
This allows the driver window regulator control switch to control the motor for normal operation.
The passenger window motors are hardwired directly to the window regulator control switches. SECTION 501-

Inspection and Verification
1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the diagnostic tool does not communicate with the vehicle, refer to the diagnostic tool manual.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If the diagnostic tool responds with: zCKT 914, CKT 915 or CKT70 - ALL ECUS NO RESP/NOT EQUIP, refer to Section 418 -
00 .
z NO RESP/NOT EQUIP for the generic electronic module (GEM), go to Pinpoint Test A.
z NO RESP/NOT EQUIP for the instrument cluster module (ICM), refer to Section 413 - 01 .
z System passed, retrieve and record the continuous diagnostic trouble codes (DTCs),
erase the continuous DTCs and carry out self- test diagnostics for the GEM or ICM.
6. If the GEM or ICM DTCs retrieved are related to the concern, go to the GEM or ICM Diagnostic Trouble Code (DTC) Index.
7. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.
