........,. POWER WINDOW SWITCH
DRIVER SEAT SIDE
This switch can be used to open and close all the
windows on both front and rear sides.
Only the switch panel at the driver seat is provided
with switches that operate the other windows.
And, only the driver's window has a "one touch"
mechanism for rolling the window all the way down
automatically. (Fig.8-202)
IL'ti'l Circuit inspection of the driver seat side

~ Remove the connectors of the driver's power
window switch, and check the voltage and
continuity between the harness side connector
terminals. (Fig.

order.
POWER WINDOW MOTOR-DRIVER
SEAT SIDE
(b!] INSPECTION
lt!l Before checking the motor, be sure to start
check the circuit
through the driver's power
window switch connector I]]] and the circuit
between drivers seat side
power window switch
and
the power window relay.
If the motor does not operate correctly, either
the motor or the circuit is defective.
1. Circuit inspection between fuse and the
ground, circuit breaker and the power
window switch-LH (Fig. 8-211)
1. Check to see if fuse C-4 (10A), circuit breaker
and
power window relay is normal. Repair or
replace the defective parts.
2. Disconnect the front power window SW-LH
connector.
3. Check to see if battery voltage applied at
71 D-5 I and the ground when starter switch is
"ON" position.
Repair a
poor connection of the connectors or
aj opel circuit between 1! B-421 and 2 "B-37!1,
