windows to be raised and lowered electrically by
actuating a switch on the instrument panel or center
console (sedan only). The front window switch allows
the front occupants to lock out the individual rear
switches from operation. The power window system
receives battery feed through a circuit breaker in the
fuse block, only when the ignition switch is in the
ON position.

In each door of the convertible there is a window

regulator module directly connected to each of the
front door window regulator motors. The modules
control window motor operation and smart glass
functions. The driver window module controls the
convertible top operations.

The power window system includes the power win-

dow switches on the instrument panel and center
console (sedan only), the circuit breaker in the fuse
block, and the power window motors.

OPERATION

The front and rear window lift motors are of the

permanent magnet type. A battery positive and neg-
ative connection to either of the two motor terminals
will cause the motor to rotate in one direction.
Reversing current through these same two connec-
tions will cause the motor to rotate in the opposite
direction.

On convertible vehicles, the convertible top switch

is hard wired to both window regulator modules by
the Power Top Switch Mux circuit. When a top oper-
ation input is received by the driver window module,
it will ground the respective relay control circuit
which in turn will operate the motor. If the convert-
ible top switch is pressed and held to the down posi-

tion second detent, it will command both modules to
drop all windows to the fully down position. The win-
dows cannot be raised when the convertible top
switch is in the top down position. When the switch
is held in the top up position and all four windows
are fully up, the modules will lower the respective
front window 40 mm, lower the respective rear win-
dow approximately 55 mm and the driver window
module will ground the top up relay control circuit.
Once the top is back up the windows will not raise
automatically.

Each individual motor is grounded through their

respective switch.

DIAGNOSIS AND TESTING - POWER
WINDOWS

WIRING VOLTAGE TEST

The following wiring test determines whether or

not voltage is continuous through the body harness
to the front switch.

(1) Remove the power window switch and bezel.
(2) Disconnect wire connector from back of power

window switch.

(3) Switch ignition to the ON position.
(4) Connect the clip end of a 12 volt test light to

Pin 4 of the window switch harness connector. Touch
the test light probe to Pin 3.

• If the test light illuminates, the wiring circuit

between the battery and switch is OK.

• If the lamp does not illuminate, first check 30

amp circuit breaker in the fuse block. If circuit
breaker is OK, then check for a broken wire.

For complete circuit diagrams, refer to the appro-

priate wiring information.

POWER WINDOW MOTOR TEST

If the power window motor is receiving proper cur-

rent and ground and does not operate, proceed with
motor test.

For complete circuit diagrams, refer to the appro-

priate wiring information.

(1) Remove front door trim panel as necessary to

gain access to power window motor wire connector.

(2) Disconnect power window motor wire connector

from door harness.

(3) Using two jumper wires, connect one to a bat-

tery (+) source and the other to a good ground (-).

(4) Connect the Negative (-) jumper probe to one of

the motor connector terminals.

(5) Momentarily touch the Positive (+) jumper

probe to the other motor connector terminal.

When positive probe is connected the motor should

rotate in one direction to either move window up or
down. If window is all the way up or down the motor
will grunt and the inner door panel will flex when
actuated in that one direction.

(6) Reverse jumper probes at the motor connector

terminals and window should now move in opposite
direction. If window does not move or grunt, replace
the motor.

If window moved completely up or down, reverse

the jumper probes and cycle window to the opposite
position to verify full operation.

If motor grunts and does not move, verify that reg-

ulator is not binding.

DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH

Remove the switch. Using an ohmmeter, test the

window switch for continuity in all positions listed in
the Continuity Table. Refer to the Power Window
Switch Continuity table to determine if continuity is
correct (Fig. 1) and (Fig. 2).

voltage from pin 13 to ground.

To test the right front down and express down

switch position, connect pin 4 to ground and pin 12
to a 12 volt source. Using a voltmeter, measure for
voltage from pin 3 to ground. If the correct results
are not obtained, replace the switch.

WINDOW REGULATOR
MODULE

DESCRIPTION

The window regulator modules are directly con-

nected to each of the front door window regulator
motors (Fig. 6). The window switches are hard wired
by a mux circuit to the respective window regulator
module. The respective rear window motor is hard
wired to the module. The front window motor is
directly attached to the module. Both front door win-
dow switches have the express down feature. The
module will cease lowering the front glass when a
fully down position is sensed through the hall effect
sensor.

When a module must be replaced, it is necessary to

replace the entire regulator assembly.

OPERATION

When a door is opened, the respective module will

receive a signal from the door ajar switch or the win-
dow drop switch. The window drop switch is directly
controlled by both the interior and the exterior door
handle switches. The drop switch is part of the door
latch. This switch is faster than the door ajar switch
to signal an open door operation. At that point the
module will drop the front door glass 10 mm. How-
ever, if the window drop switch should fail, the door
ajar sense would also drop the window 10 mm and
the module would set a trouble code. When the mod-
ule then receives a door ajar switch open (door
closed) it would raise the window 10 mm. The mod-
ule knows the position of the window by counting the
motor rotation through the hall effect sensor in the
module. If a door window is raised while that door is
open, the module will raise the glass up, but when
the door is closed it will raise the glass an additional
10 mm. When the convertible top down switch is
