DESCRIPTION AND OPERATION
POWER WINDOWS (NORMAL OPERATION)
NOTE: The power window system used in this vehi-
cle is different from other vehicles in that a window
timer module along with window down relays are
used. This module allows for notmal window oper-
ation when the window switches are activated.
However, when the power top switch is activated
the module will partially lower all windows
The power window system is powered by a 20 amp
circuit breaker located in the junction block cavity
19. This circuit breaker also supplies power to the
window down module and normally OPEN contacts
of the window down relays.
The circuit breaker receives its feed from the igni-
tion switch on the A22 circuit. This circuit breaker is
HOT when the ignition switch is in the RUN position
only.
Circuit F21 is the feed circuit from the circuit
breaker to the power window switches. The ground
path for the power windows, window timer module,
and window down relays is on the Z1 circuit and ter-
minates at the instrument panel left side cowl.
Both of the door switches have a Light Emitting
Diode (L.E.D.) located inside of the switch. This diode
allows the operator to see the switch when it is dark.
The diodes are powered at all times when the igni-
tion switch is in the RUN position.
Resistors and diodes internal to the switches are
used for the L.E.D’s. No attempt should be made to
repair these items. If the L.E.D. is not working, the
switch should be replaced.
Each window motor has an internal circuit breaker
to protect the motor from excessive electrical loads.
This circuit breaker is not serviceable.
LEFT FRONT WINDOW OPERATION
When the operator selects window DOWN opera-
tion power is supplied on the F21 circuit through the
switch to circuit Q29. Circuit Q29 connects from the
switch to the left power window down relay. The feed
is passed through the normally CLOSED contacts in
the relay to circuit Q21. Circuit Q21 connects from
the relay to the motor. Ground for the motor is sup-
plied on circuit Q11 back to the master switch to the
Z1 ground circuit.
For window UP operation the circuits are reversed.
Circuit Q11 is the feed and circuits Q21 and Q29 are
the ground.
RIGHT FRONT WINDOW OPERATION
When the DRIVER selects window DOWN opera-
tion power is supplied on the F21 circuit through the
switch to circuit Q30. Circuit Q30 connects from the
drivers door switch to the right front down relay. The
feed is passed through the normally CLOSED con-
tacts in the relay to circuit Q26. Circuit Q26 connects
to the passenger switch. The motor current then runs
through th eswitch to circuit Q22 which connects to
the motor. The ground returns through circuit Q12
through the passengers switch contacts to circuit
Q16. Circuit Q16 connects to th master switch then
to the Z1 ground circuit.
For window UP operation the circuits are reversed.
Circuit Q16 is the feed and circuits Q26 and Q30 are
the ground.
If the switch is being operated from the PASSEN-
GER’S front door, and the operator is requesting win-
dow DOWN operation, power is supplied on the F21
circuit through the switch to the Q22 circuit.
Ground for the motor is supplied on the Q12 circuit
through the switch and back to the master switch on
circuit Q16. A bus bar, internal to the switch, con-
nects the Q16 circuit to the Z1 circuit. The Z1 circuit
is terminated at the instrument panel left side cowl.
For window UP operation, the circuits are
reversed. Circuit Q12 is the power and circuits Q22
and Q26 are the ground.
LEFT REAR WINDOW
When the DRIVER selects window DOWN opera-
tion power is supplied on the F21 circuit through the
switch to circuit Q31. Circuit Q31 connects from the
drivers door switch to the window timer module. The
power is passed though the normally CLOSED con-
tacts in the module to circuit Q27. Circuit Q27 con-
nects from the module to the motor.
