Toyota Sienna Service Manual: Rear Air Outlet Damper Control Servo Motor Circuit

DESCRIPTION

This circuit turns the servo motor and changes each damper position by receiving the signals from the A/ C amplifier.

The rear air outlet damper servo motor switches the air outlet mode by rotating (normal, reverse) with electrical power from the A/C amplifier.
