Hyundai Accent (HC): Heater / Auto Defoging Actuator

- Components Location

1. Auto logging actuator


- Description The auto defogging sensor is installed on 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. - Inspection

1.Turn the ignition switch OFF.

2.Disconnect the auto defogging connector.

3.Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the auto defogging actuator operates to the close position when connected in reverse.

4.Connect the auto defogging actuator connector.

5.Turn the ignition switch ON.

6.Check the voltage between terminals 6 and 5.

   

• It will feedback the current position of the actuator to controls.

Specification
Door positionVoltage (V)Error detecting
Vent4.7 ± 0.15High voltage : 2.06V or more
Defrost2.06 ± 0.15Low voltage : 2.06V or less

7.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.

- Diagnosis With GDS

1.The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS).※ The diagnostic system (GDS) provides the following information.(1) Self diagnosis : Checking the failure code (DTC) and display.(2) Current data : Checking the system input/output data state.(3) Actuation test : Checking the system operation condition.(4) Additional function : Other controlling such as he system option and zero point adjustment.

2.Select the 'Car model' and the system to be checked in order to check the vehicle with the tester.

3.Select the 'Current data' menu to search the current state of the input / output data.The input / output data for the sensors corresponding to the Auto Defogging Actuator can be checked.

4.To perform compulsory operation on Auto Defogging Actuator input factors, select "ACTUATION TEST".

- Replacement

1.Disconnect the negative (-) battery terminal.

2.Remove the main crash pad assembly.(Refer to Body - "Main Crash Pad Assembly")

3.Disconnect the connector (A) and then remove the auto defogging actuator (B) after loosening the mounting screws.

4.To install, reverse the removal procedure.
