This sensor detects the position of the air outlet damper and sends the appropriate signals to the air conditioning control assembly.
The position sensor is built into the air outlet servomotor assembly.

 

Air Outlet Servomotor Circuit



Circuit Description
This circuit turns the servomotor and changes each mode damper position by the signals from the A/C control assembly. When the AUTO switch is on, the A/C control assembly changes the mode automatically between (FACE), (BI-LEVEL) and (FOOT) according to the temperature setting.

 

Thank you very very much!! thats exactly what i was looking for

No prob, hope you fix the problem.

 

Well, was this problem fixed?

Hildi has the same problem with her SC, and it'd help to know what you ended up doing.

EDIT: Hildi ended up bypassing, rather than fixing the problem.
