3. Install the motor in the reverse order of removal. After installation, make sure the motor runs smoothly.  

RECIRCULATION CONTROL MOTOR TEST 

1. Disconnect the 7P connector from the recirculation control motor. 

2. Connect battery power to the No. 1 terminal of the recirculation control motor, and ground the No. 5 and 

No. 7 terminals; the recirculation control motor should run smoothly. To avoid damaging the recirculation 
control motor, do not reverse power and ground. Disconnect the No. 5 or No. 7 terminals from ground; 
the recirculation control motor should stop at Fresh or Recirculate. Don't cycle the recirculation control 
motor for a long time.

3. If the recirculation control motor did not run in step 2, remove it, then check the recirculation control 

linkage and doors for smooth movement. 

NOTE:

Incorrectly applying power and ground to the recirculation control motor 
will damage it. Follow the instructions carefully.



If the linkage and doors move smoothly, replace the recirculation control motor.  



If the linkage or doors stick or bind, repair them as needed.  

RECIRCULATION CONTROL MOTOR REPLACEMENT 

1. Remove the ECM/PCM (see ECM/PCM REPLACEMENT ).  

2. Remove the bolt and the bracket (A). Disconnect the 7P connector (B) and the harness clip (C) from the 

recirculation control motor (D). Remove the self-tapping screws and the recirculation control motor from 
the blower unit.

3. Install the motor in the reverse order of removal. After installation, make sure the motor runs smoothly.  

POWER TRANSISTOR TEST 

1. Disconnect the 4P connector from the power transistor.  

2. Measure the resistance between the No. 3 and No. 4 terminals of the power transistor. It should be about 

1.4-1.5 kohms. 



If the resistance is within the specifications, go to step 3.  



If the resistance is not within the specifications, replace the power transistor.  

NOTE:

Also check the blower motor. Power transistor failure can be caused by a 
defective blower motor.

3. Carefully release the lock tab on the No. 1 terminal (BLU/YEL) (A) in the 4P connector, then remove the 

terminal and insulate it from body ground.

4. Reconnect the 4P connector to the power transistor.  

5. Supply 12 V to the No. 1 cavity with a jumper wire.  

6. Turn the ignition switch ON (II), and check that the blower motor runs. 



If the blower motor does not run, replace the power transistor.  



If the blower motor runs, the power transistor is OK.  

HEATER CONTROL PANEL REMOVAL/INSTALLATION 

1. Remove the center panel (see CENTER PANEL REMOVAL/INSTALLATION ).  

2. Remove the self-tapping screws and the heater control panel (A) from the center panel (B).

3. Install the control panel in the reverse order of removal. After installation, operate the various functions to 

see whether they works properly.  

4. Run the self-diagnostic function to confirm that there are no problems in the system (see RESETTING 

THE SELF-DIAGNOSTIC FUNCTION ).  

DUST AND POLLEN FILTER REPLACEMENT 

1. Open the glove box. Remove the glove box stop on each side, then hang the glove box down (see 

GLOVE BOX REMOVAL/INSTALLATION ).  

2. Remove the filter lid (A) from the blower unit, then pull out the first dust and pollen filter (B). Slide the 

second filter to the left, and pull it out.
