Description |
Installed on the windshield glass, the auto defogging sensor judges and sends signal to blow out wind for defogging if moisture occurs. The air conditioner control module receives a signal from the sensor and restrains moisture and eliminates defog by the intake actuator, A/C, auto defogging actuator, blower motor rpm and mode actuator.
Inspection |
1. |
Turn the ignition switch OFF. |
2. |
Disconnect the auto defogging connector. |
3. |
Verify that the auto defogging actuator operates in the open position when connecting 12V to terminal 4 and grounding terminal 6. Verify that the auto defogging actuator operates in the closed position when connected in reverse.
|
4. |
Connect the auto defogging actuator connector. |
5. |
Turn the ignition switch ON. |
6. |
Check the voltage between terminals 5 and 6. Specification
The current position of the actuator will be sent to the control unit. |
7. |
If the measured voltage is not within specification, substitute with a known-good auto defogging actuator and check for proper operation. |
8. |
Replace the auto defogging actuator if it is proved that there is a problem with it. |
Replacement |
1. |
Disconnect the negative (-) battery terminal. |
2. |
Remove the glove box housing. (Refer to Body - "Glove Box Housing") |
3. |
Remove the passenger side shower duct (A) after loosening the screw.
|
4. |
Remove the aspirator. |
5. |
Disconnect the connector (A) and then remove the auto defogging actuator (B) after loosening the screws.
|
6. |
Install in the reverse order of removal.Heating, Ventilation And Air Conditioning |
