Hyundai Tucson: Mode control actuator
Components Location
- Mode control actuator
Inspection
- Turn the ignition switch OFF.

- Connect the mode control actuator connector.
- Turn the ignition switch ON.
- Check the voltage between terminal 5 and 4.
* It will feedback the current position of the actuator to controls.
- If the measured voltage is not within specification, substitute with a known-good mode control actuator and check for proper operation.
- Replace the mode control 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")
- Remove the DC DC converter.
(Refer to Engine Electrical System - "DC DC converter")
- Disconnect the mode control actuator connector (A) and loosen the mounting screw and remove the mode control actuator (B).
- Install in the reverse order of removal.
Description
The auto defogging sensor is installed on the front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. 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.
