3. Driver ’s Side:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and negative (−) lead to terminal 1. Check that the motor
turns (moves upward).
(b) Reverse the polarity, check that the motor turns the oppo-
site way (moves downward).
If operation is not as specified, replace the motor.
4. Passenger ’s Side:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and negative (−) lead to terminal 1. Check that the motor
turns (moves upward).
(b) Reverse the polarity, check that the motor turns the oppo-
site way (moves downward).
If operation is not as specified, replace the motor.
5. Using an ammeter:
INSPECT ONE TOUCH POWER WINDOW
(a) Disconnect the connector the master switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 3 on the wire harness side connector and the negative
(−) lead to negative terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
4 on the wire harness side connector.

(d) As the window goes down, check that the current in-
creases to approximately 7.0 A.
(e) Check that the current increases to approximately 14.5 A
or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so that the check must be made before
the circuit breaker operates.
If the operation is as specified, replace the master switch.
6. Using an ammeter with a current−measuring probe:
INSPECT ONE TOUCH POWER WINDOW
(a) Remove the master switch with connector connected.
(b) Attach a current−measuring probe to terminal 3 of the
wire harness.
(c) Turn the ignition switch ON and set the power window
switch in the down position.
(d) As the window goes down, check that the current in-
creases to approximately 7.0 A.
(e) Check that the current increases to approximately 14.5 A
or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so that the check must be made before
the circuit breaker operates.
If operation is as specified, replace master switch.
7. INSPECT CIRCUIT BREAKER OPERATION
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the battery to terminal
3 and the negative (−) lead to terminal 4 on the wire har-
ness side connector, and raise the window to full closed
position.
(c) Continue to apply voltage, check that there is a circuit
breaker operation noise within approximately 4 − 40 se-
conds.
(d) Reverse the polarity, check that the window begins to de-
scend within approximately 60 seconds.
If operation is not as specified, replace the motor.

4. INSPECT DRIVER’S DOOR LOCK MOTOR OPERA-
TION
(a) Connect the positive (+) lead from the battery to terminal
3 and the negative (−) lead to terminal 7, check that the
door lock link moves to UNLOCK position.
(b) Remove the polarity, check that the door lock link moves
to LOCK position.
If operation is not as specified, replace the door lock assembly.
5. INSPECT PASSENGER’S DOOR LOCK MOTOR OP-
ERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (−) lead to terminal 6, check that the
door lock moves to UNLOCK position.
