INTAKE DOOR MOTOR

System Description

INFOID:0000000006164760

SYSTEM DESCRIPTION

SYMPTOM:

• Intake door motor does not operate normally.

• Intake door does not change.

SYSTEM DESCRIPTION

Component Parts

Intake door control system components are:

• Front air control

• Intake door motor (PRB built into the intake door motor)

• Ambient sensor

• Intake sensor

System Operation

The intake door control determines the intake door position based on the position of the recirculation switch.

When the recirculation switch is depressed the intake door motor rotates closing off the fresh air inlet and

recirculating the cabin air. If the recirculation switch is depressed again, the intake door motor rotates in the

opposite direction, again allowing fresh air into the cabin.

Intake Door Control Specification

COMPONENT DESCRIPTION

Intake door motor

The intake door motor is attached to the intake unit. It rotates so that

air is drawn from inlets set by the front air control. Motor rotation is

conveyed to a lever which activates the intake door.

Intake Door Motor Component Function Check

INFOID:0000000006164761

INSPECTION FLOW

1.

CONFIRM SYMPTOM BY PERFORMING OPERATIONAL CHECK - REC (

)

1. Press the vent mode switch (

).

2. Press REC (

) switch. The REC (

)indicator should illuminate.

3. Press REC (

) switch again. The REC (

) indicator should go out.

4. Listen for intake door position change (you should hear blower sound change slightly).

DIAGNOSTIC PROCEDURE FOR INTAKE DOOR MOTOR

SYMPTOM:

• Intake door does not change.

• Intake door motor does not operate normally.

1.

CHECK INTAKE DOOR MOTOR CIRCUITS FOR OPEN AND SHORT TO GROUND 

1. Turn ignition switch OFF.

2. Disconnect the front air control harness connector M180 (A) and

the intake door motor harness connector M58 (B).

3. Check continuity between front air control harness connector

M180 (A) terminals 21, 22 and the intake door motor harness

connector M58 (B) terminals 1, 6.

4. Check continuity between front air control harness connector

M180 terminals 21, 22 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness as necessary.

2.

CHECK FRONT AIR CONTROL FOR INTAKE AIR DOOR MOTOR POWER AND GROUND 

1. Reconnect front air control harness connector.

2. Turn ignition switch ON.

3. Check voltage between front air control harness connector

M180 terminal 21 and terminal 22 while placing the HVAC sys-

tem into self-diagnostic mode.

Is the inspection result normal?

YES

>> Inspect intake air door for binding or mechanical failure. If intake air door moves freely, replace the

intake air door motor. Refer to 

VTL-18, "Removal and Installation"

.

NO

>> Replace front air control. Refer to 

VTL-8, "Removal and Installation"
