STEP
INSPECTION
ACTION
*10
CHECK TO SEE WHETHER MALFUNCTION
(LACK OF CONTINUITY) IS IN WIRING
HARNESS (BETWEEN CUMATE CONTROL
UNIT AND AIR MIX ACTUATOR) OR
ELSEWHERE
• Turn ignition switch to ON position.
• Test voltage at following air mix actuator
connector terminal E (+5 V signal).
• Is voltage
approximately 5 V?
Yes
Go to next step.
No
Repair wiring harness between climate control
unit and air mix actuator, then go to Step 19.
*11
CHECK TO SEE WHETHER MALFUNCTION
(LACK OF CONTINUITY) IS IN WIRING
HARNESS (BETWEEN CLIMATE CONTROL
UNIT AND AIR MIX ACTUATOR) OR
ELSEWHERE
• Turn ignition switch to LOCK position.
• Disconnect climate control unit connector
(16-pin) and air mix actuator connector.
• Is there continuity between climate control unit
connector (16-pin) terminal 2J (potentiometer
input signal) and air mix actuator connector
terminal B?
Yes
Go to next step.
No
Repair wiring harness between climate control
unit and air mix actuator, then go to Step 19.
*12
CHECK TO SEE WHETHER MALFUNCTION
(SHORT TO GROUND) IS IN WIRING
HARNESS (BETWEEN CUMATE CONTROL
UNIT AND AIR MIX ACTUATOR) OR
ELSEWHERE
• Is there continuity between climate control unit
connector (16-pin) terminal 2J (potentiometer
input signal) and ground?
Yes
Repair wiring harness between climate control
unit and air mix actuator, then go to Step 19.
No
Go to next step.
*13
CHECK TO SEE WHETHER MALFUNCTION
(SHORT TO B+) IS IN WIRING HARNESS
(BETWEEN CLIMATE CONTROL UNIT AND
AIR MIX ACTUATOR) OR ELSEWHERE
• Turn ignition switch to ON position.
• Test voltage at climate control unit connector
(16-pin) terminal 2J (potentiometer input
signal).
• Is voltage
approximately
12 V?
Yes
Repair wiring harness between climate control
unit and air mix actuator, then go to Step 19.
No
Go to next step.
*14
CHECK TO SEE WHETHER MALFUNCTION
(LACK OF CONTINUITY) IS IN WIRING
HARNESS (BETWEEN CLIMATE CONTROL
UNIT AND AIR MIX ACTUATOR) OR
ELSEWHERE
• Turn ignition switch to LOCK position.
• Is there continuity between following climate
control unit connector (12-pin) terminals and
air mix actuator connector terminals?
— Terminal 11 and Terminal C (potentiometer
GND signal)
— Terminal 1B and Terminal A (motor drive
signal)
— Terminal 1L and Terminal F (motor drive
signal)
Yes
Go to next step.
No
Repair wiring harness between climate control
unit and air mix actuator, then go to Step 19.
15
INSPECT HEATER UNIT AIR MIX ACTUATOR
UNK AND CRANK
• Is there grease on the link and crank?
Yes
Go to next step.
No
Apply grease, then go to Step 19.
16
INSPECT AIR MIX ACTUATOR
• Inspect air mix actuator.
• Is it okay?
Yes
Go to next step.
No
Replace air mix actuator, then go to Step 19.
