Air Mix Damper Control Servo Motor Circuit (Passenger Side) (B1441/41)
DESCRIPTION
The air mix control servo motor sends pulse signals to indicate the damper position
to the A/C amplifier. The A/C amplifier activates the motor (normal or reverse)
based on these signals to move the air mix damper (front passenger side) to any ...
