Front driver-side door control module, purpose - GF72.29-P-4105-03TT
The left front door control module (N69/1) has the following purposes:
Scanning the following switches:
- Left front power window switch (S20/1s1)
- Left rear power window switch (S20/1s3)

Reading in the following sensors:
- Left electrically adjustable and heated outside mirror (M21/1)
- Hall signals for left front power window motor (M10/3)
- Left front IR receiver (A26/1)
Switching loads via semiconductor switches:
- Left front power window motor (M10/3)
- Left rear power window motor (M10/5)
- Left front door CL motor (M14/6)
- Left electrically adjustable and heated outside mirror (M21/1)
- Mirror heater (M21/1r1)
- Automatic mirror dimming feature (M21/h1)
- Mirror memory
- Mirror in park position
- Folding mirror
- Seat adjustment switch
- Turn signal lamps for left electrically adjustable and heated outside mirror (M21/1)
- Entrance lamp actuation
- Door inside handle illumination
- Switch and controls illumination for all switches connected to the door control module
The left front door control module (N69/1) is connected with passenger compartment CAN bus for exchanging data.
The left front door control module (N69/1) is coded as driver or passenger control module via the EIS control module (N73). This description applies by analogy to vehicles with right-hand steering
Purpose in combination with air conditioning system
The driver-side front door control module (N69/1) senses the window position of the driver's door and stores this information on the passenger compartment CAN bus.
The AC pushbutton control module (N22) or comfort AC pushbutton control module (N22/7) reads in the signal for the position of the driver's window to obtain a better control quality.
Recirculated air convenience closing, purpose
The convenience closing function is activated by pressing the recirculated air button (N22s2 or N22/7s2) for longer than 1.5 s. The left front door control module (N69/1) stores the momentary window position and then closes the window in the one-touch up mode when it is open.
When the convenience closing function is terminated by pressing the recirculated air switch (N22s2 or N22/7s2) for longer than 1.5 s, the window is moved back to the stored position.
