Circuit Description
WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
The air mix control servomotor (air mix damper servo sub-assy) is controlled by the A/C amplifier. Air flow temperature changes when moving the air mix damper to the target point. The target point can be detected with the air mix damper position sensor.
