Air Mix Damper Control Servo Motor Circuit (Driver Side)
DESCRIPTION
The air mix control servo motor (air mix damper servo sub-assembly) is
controlled by the A/C amplifier.
The air mix control servo motor moves the air mix damper by rotating (normal,
reverse) with electrical
power from the A/C amplifier.
This adjusts the mix ratio of the air t ...
