Inspection

1.	Ignition "OFF”

2.	Disconnect the connector of mode control actuator.

3.	Verify that the mode control actuator operates to the defrost mode when connecting 12V to the terminal 3 and grounding terminal 4.

4.	Verify that the mode control actuator operates to the vent mode when connecting in the reverse. 1. - 2. - 3. Defrost mode 4. Vent mode 5. Sensor ground 6. Feedback signal 7. Sensor (+5V)

5.	Check the voltage between terminals 6 and 5. Door position Voltage (6-5) Error detecting Vent 0.45 ± 0.15V Low voltage : 0.1V or less Bi-Level 1.4 ± 0.15V Floor 2.45 ± 0.15V Mix 3.5 ± 0.15V Defrost 4.55 ± 0.15V High voltage : 4.9V or more It will feedback current position of actuator to controls.

6.	If the measured voltage is not specification, substitute with a known-good mode control actuator and check for proper operation.

7.	If the problem is corrected, replace the mode control actuator.

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the side cover (A).

3.	Remove the fuse box cover (A) and loosen the mounting screws and then remove the crash pad lower cover (B).

4.	Disconnect the diagnosis connector (A).

5.	Remove the shower duct (A).

6.	Disconnect the temperature control actuator connector (A) and loosen the mounting screws and then remove the temperature control actuator (B).

7.	Installation is the reverse order of removal.
