INSPECTION OF SERVO MOTOR
INSPECT SERVO MOTOR OPERATION
(a) With the positive (+) lead from the battery to terminal
8 and negative (±) lead to terminal 2, check that the
lever moves smoothly from WARM to COOL.
The resistance values from COOL to WARM will suc-
cessively decrease.
If operation is not as specified, replace the servo motor.(b) With the positive (+) lead from the battery to terminal
1 and negative (±) lead to terminal 3, check that the
lever moves smoothly from RECIRC to FRESH.
If operation is not as specified, replace the servo motor.
(b) With the positive (+) lead from the battery to terminal
2 and negative (±) lead to terminal 8, check that the
lever moves smoothly from COOL to WARM.
(c) While operating the servo motor from either points
(a) or (b), measure the resistance values of terminals
13 and 15.

2. INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to ter-
minal 1 and negative (±) lead to terminal 2, check
that the motor turns.
(b) Connect the positive (+) lead from the battery to ter-
minal 2 and negative (±) lead to terminal 1, check
that the motor turns the opposite way.
If operation is not as specified, replace the motor. (b) With the window in the full closed position, hold the
switch in ºDOWNº and check that the window begins
to descend within 60 seconds.
If operation is not as specified, replace the motor.

(Door Lock Signal)
HINT: When the relay circuit is as specified, inspect the
door lock signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter
to terminal 3 and the negative (±) lead to the ter-
minal 4.
(c) Set the door lock manual switch to UNLOCK,
check
that the voltage rises from 0 volts to battery volt-
age for approximately 0.2 seconds.
