DESCRIPTION
This circuit turns the servo motor and changes each damper position by receiving the signals from the A/ C amplifier.
The air outlet damper servo motor switches the air outlet mode by rotating (normal, reverse) with electrical power from the A/C amplifier.
When the AUTO switch is on, the A/C amplifier changes the mode between "FACE",
"FACE/FOOT" and
"FOOT" according to the temperature setting.

INSPECTION PROCEDURE
1 READ VALUE OF INTELLIGENT TESTER
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.
(c) Select the items below in the DATA LIST, and read the display on the intelligent tester.
DATA LIST / AIR CONDITIONER
OK: When the target position is "FACE" (0%), the actual opening angle is 19.0% or less.
When the target position is "DEF" (100%), the actual opening angle is 81.0% or more.

2 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.
(c) Select the item below in the ACTIVE TEST and then check that the air flow position by hand.
ACTIVE TEST / AIR CONDITIONER
OK: Air comes out from the selected air outlet.

3 PERFORM ACTUATOR CHECK
(a) Warm up the engine.
(b) Enter the actuator check mode (See page AC-15).
(c) Press the DEF switch and change to step operation.
(d) Press the DEF switch and check the air flow by hand.
OK: Air outlet mode changes in accordance with each display code.
Result
4 INSPECT AIR OUTLET CONTROL SERVO MOTOR
(a) Remove the air outlet control servo motor.
(b) Disconnect the connector from the air outlet control servo motor.
(c) Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 5, then check that the lever turns to the "DEF" position smoothly.
OK: Lever turns to "DEF" position smoothly.
(d) Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 4, then check that the lever turn to the "FACE" position smoothly.
OK: Lever turns to "FACE" position smoothly.
5 CHECK HARNESS AND CONNECTOR (AIR OUTLET CONTROL SERVO MOTOR - A/C AMPLIFIER)
(a) Disconnect the connector from the A/C amplifier.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
REPLACE A/C AMPLIFIER

Auto Up / Down Function does not Operate
DESCRIPTION
If the AUTO UP/DOWN function does not operate, any of the following troubles
may be the cause:
When the PWR fuse or the power window relay (Marking: PWR) is
replaced with new ones, or when
the battery terminal and the connector of the power window master switch are
