5.	Switch "ON" the ignition.

Check the voltage between terminals 4 and 5.

Specification

Door position	Voltage (V)	Error detecti
Vent	0.3 ± 0.15	Low voltage : 0.1V or less
Defrost	4.7 ± 0.15	High voltage : 4.9V or more

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

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

8.	Replace the mode control actuator if it is proved that there is a problem with it.

Replacement
