Recirculation Damper Servo Motor Circuit: Description
WARNING: This page is about a different car, the 2011 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
The recirculation damper servo motor and No. 1 heater control (air inlet control switch) are powered through the HTR-IG fuse. Operating the No. 1 heater control (air inlet control switch) drives the recirculation damper servo motor to switch between "FRESH" and "RECIRCULATION".
