It is electronically operated by a servo motor controlled by the logicon.
The air mix motor is a common failure. Start your fix by first resoldering the logicon. If that doesn't fix it, replace the air mix motor. If that doesn't fix it, replace the logicon. There are also testing procedures for the motor in the FSM.
