INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (±) lead to terminal 2, check that the
motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
If operation is not as specified, replace the motor.
NOTICE:
Since the jam protection may not work properly be sure to
conduct procedures described in ºHOW TO RESET POW-
ER MOTOR (RESET AND PULSE SWITCH)º after this in-
spection.
7. Passenger 's door and rear right door:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (±) lead to terminal 2, check that the
motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
