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.

5.	Check the voltage between terminals 5 and 6. Door position Voltage (5-6) Error detecting Vent 0.3 ± 0.15V Low voltage : 0.1V or less Defrost 4.7 ± 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 crash pad lower panel (A)

3.	After loosening the mounting bolts, then remove the reinforcing panel (A).

4.	Disconnect the mode control actuator connector (A) after removing the air duct.

5.	Loosen the mounting screws and then remove the mode control actuator (B).

6.	Installation is the reverse order of removal.
