Before checking to see if the motor functions correctly,
be sure to check the circuit through the connector 
of the driver’s power window switch.
If the motor does not operate smoothly, either the motor
or the circuit between the switch and the motor is defec-
tive.

Disconnect the switch connector and apply battery
voltage to the harness side connector terminals to
check its function.
