DTC B1443/43 Air Outlet Damper Control Servo Motor Circuit: Description
WARNING: This page is about a different car, the 2007 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The damper servo sends pulse signals to indicate the damper position to the air conditioning amplifier. The air conditioning amplifier activates the motor (normal or reverse) based on these signals to move the mode damper to the appropriate position, which controls the air outlet modes.
HINT:
Confirm that there are no mechanical problems because this DTC can be output when either a damper link or damper is mechanically locked.
