Hyundai Tucson: Auto defogging actuator
Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Heating, Ventilation and Air Conditioning (HVAC) / Heater / Auto defogging actuator
Components Location

- Auto defogging actuator
Inspection
- Turn the ignition switch OFF.
- Disconnect the auto defogging connector.
- Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 3 and grounding terminal 6
Verify that the auto defogging actuator operates to the close position when connected in reverse.

- Sensor (+ 5V)
- Feedback signal
- Sensoer ground
- Connect the auto defogging actuator connector.
- Turn the ignition switch ON.
- Check the voltage between terminals 5 and 4.

* It will feedback the current position of the actuator to controls.
- If the measured voltage is not within specification, check the operation by replacing the existing auto defogging actuator with a new genuine part. After that, determine whether replacement of the auto defogging actuator is required or not.
- Replace the auto defogging actuator if it is proved that there is a problem with it.
Replacement
- Disconnect the negative (-) battery terminal.
- Remove the main crash pad assembly.
(Refer to Body (Interior and Exterior) - "Main Crash Pad Assembly")
- Disconenct the connector (A) and loosen the mounting screws and remove the auto defogging actuator (B).

- Install in the reverse order of removal.
