Component Identification
Location
The actuator motors are located on the A/C housing and are located at the respective positions as shown in the picture above.
Task
General information on actuator motors and flap control Continuous positioning of the flaps.
To prevent the actuator motors from continuously running in the controlled range, the following release function is implemented for each flap in the
automatic air conditioning.
Release function: Once a position has been adjusted, then until the next change, the specified temperature of the blown in air for example must change by
so much that the release value going above or below it is either not reached or exceeded.
Final values are approached directly (0 %, 100 %).
Anti-fogging function
The anti-fogging function prevents the windshield and side windows from fogging up after starting the engine thanks to the fact that moist air is not
guided directly against the windows after starting, but instead into the footwell of the vehicle.
Left center air flap actuator motor and right center air flap actuator motor
The left center air flap actuator motor and the right center air flap actuator motor operate the particular air flap that controls the air flow to the center
nozzles separately for left and right.
Depending upon the desired air outlet temperature at the center nozzle, the left center air flap actuator motor and the right center air flap actuator motor
are actuated via the comfort AAC [KLA] control and operating unit (N22/7).
