Turn the ignition switch OFF.
Disconnect the mode control actuator connector.
Verify that the mode control actuator operates to the defog mode when connecting 12V to terminal 3 and grounding terminal 4.
Verify that the mode control actuator operates to the vent mode when connected in reverse.

It will feedback the current position of the actuator to the controls.
If the measured voltage is not within specification, substitute with a known-good mode control actuator and check for proper operation.
If the problem is corrected, replace the mode control actuator.
Disconnect the negative (-) battery terminal.
Remove the crash pad lower panel.
