DESCRIPTION AND OPERATION
INTRODUCTION
All four power windows can be controlled by the
switches on the Drivers Door Module (DDM). Addi-
tionally, the left rear window as well as the right
front and right rear windows have separate switches.
The switch pod on the DDM a contains lock out
switch. The lock-out feature prevents the windows
from being operated by any switch other than the
drivers door switch.
Each rear window switch contains an LED. The
DDM prevents illumination of the LEDs when the
operator selects the window lock-out feature.
POWER WINDOWS
Circuit A250 from fuse 11 in the Power Distribu-
tion Center (PDC) powers circuit F81 through the cir-
cuit breaker in cavity 2 of the junction block. Circuit
F81 supplies power to the Drivers Door Module
(DDM) and the Passengers Door Module (PDM). The
DDM and PDM operate the power windows. Circuit
Z1 provides ground for the power window system.
LEFT FRONT WINDOW OPERATION
The Drivers Door Module operates the left front
window. When the operator selects window DOWN
operation, the DDM connects circuit F81 to circuit
Q21. Circuit Q21 goes from the switch to the power
window motor. Ground for the motor is supplied on
the Q11 circuit back to the switch. The DDM con-
nects circuit Q11 to ground circuit Z1.
For window UP operation the circuits are reversed.
The DDM connects circuit Q11 to circuit F81 and
connects circuit Q21 to ground circuit Z1.
RIGHT FRONT WINDOW OPERATION
The Passengers Door Module (PDM) operates the
right front window. If the DRIVER operates the pas-
senger window, the Drivers Door Module signals the
Passengers Door Module over the CCD Bus.
For window DOWN operation, the PDM connects
circuit F81 to circuit Q22. Circuit Q22 goes from the
power window switch circuitry in the PDM to the
power window motor. Ground for the motor is sup-
plied on circuit Q12 back to the switch. The DDM
connects circuit Q12 to ground circuit Z1.
For window UP operation the circuits are reversed.
The PDM connects circuit Q12 to circuit F81 and
connects circuit Q22 to ground circuit Z1.
LEFT REAR WINDOW
Circuits Q17 and Q27 connect the Driver’s Door
Module (DDM) to the left rear window switch. When
the operator has not selected the window lock-out
feature, the DDM connects circuits Q17 and Q27 to
battery voltage. At the left door harness, circuit Q17
connects to circuit Q18 and circuit Q27 connects to
circuit Q28. Circuits Q18 and Q28 connect to the left
rear power window switch.
If the window is operated from left rear switch for
window DOWN operation, the switch connects circuit
Q12 from the power window motor to ground on cir-
cuit Z1. The left rear window switch connects circuit
Q28 to circuit Q22. Circuit Q22 powers the window
motor. Circuits Q12 and Z1 provide ground.
For window UP operation the circuits are reversed.
The left rear window switch connects Q22 to ground
on circuit Z1. Circuit Q18 powers the rear window
motor. Circuits Q22 and Z1 provide ground.
The left rear window switch contains a Light Emit-
ting Diode (LED). The DDM illuminates the LED on
circuit E21. Circuit E21 connects to circuit E20 at
the left door harness. Circuit E20 connects to the left
rear window switch and powers the LED.
If the operator has selected the window lock-out
feature, the DDM will not supply power to the left
rear window switch on circuits Q27 and Q17. Also,
the DDM does not illuminate the LED in the switch.
If the window is operated from DRIVER’S switch
for window DOWN operation, the DDM powers cir-
cuit Q27 and grounds circuit Q17. Circuit Q27 con-
nects to circuit Q28 at the left rear door harness.
From circuit Q28, current passes through the closed
contacts in the left rear window switch to circuit
Q22. Circuit Q22 powers the window motor. The
ground path for the motor is on circuit Q12 from the
motor, through the closed contacts in the left rear
window switch to circuit Q18, to Q17 back to the
DDM.
