Defog Actuator Repair Procedures

Inspection

1. 1
   Ignition "OFF".
2. 2
   Disconnect the auto defog control actuator connector.
3. 3
   Make sure the auto defog actuator operates in the defrost mode ON when 12 V is applied to terminal 3 and terminal 7 is grounded.
4. 4
   Make sure the auto defog control actuator operates in the defog OFF mode when the polarity is reversed.

   

   1. - 2. - 3. DEF (open) 4. Sensor F\REF (+5V)

   5. Feedback signal 6. Sensor ground 7. DEF (close)

5. 5
   Check the voltage between terminals 5 and 6.

   Door Position	Voltage (5-6)	Fault Detection
   Defog (OFF)	0.3 ± 0.15 V	Low voltage: 0.1 V or less
   Defog (ON)	4.7 ± 0.15 V	High voltage: 4.9 V or more

   
   It transmits the current position of the actuator to the control unit.
6. 6
   If the measured voltage does not meet the specification, replace with a known good auto defog actuator and check that it operates correctly.
7. 7
   If the problem is resolved, replace the auto defog actuator.
