GF72.29-P-3010Q Power Window Comfort Opening Via Recirculated Air Button, Function

Component Identification:

Function requirements
^ Terminal 15 ON
^ No undervoltage or overvoltage
^ Windows normalized
^ Previous comfort closing via recirculated air (the stored positions remain stored for 5 min. after circuit 15R or circuit 15 OFF when the front doors are closed)

Function interruption (all windows) when
^ actuation request is canceled,
^ the CAN class B message is not present

Function interruption (individual windows) when
^ the corresponding power window switches are actuated in any direction
^ Lock-up recognition

Opening function via recirculated air
When the recirculated air switch (N22s2) on the AAC control and operating module (N22) or the recirculated air switch (N22/7s2) on the comfort AAC control and operating module (N22/7) is pressed and held down, the windows can be opened to their previously stored position via recirculated air switch after previous comfort closing.

The actuation request is relayed to the left door control module (N69/1), right door control module (N69/2) and rear control module (N22/6) (on model 209.3) or power soft top control module (on model 209.4) by the AAC control and operating module (N22) or comfort AAC control and operating module (N22/7) via CAN class B bus, which then actuates the corresponding power window motors (M10/3, M10/4, M10/5 and M10/6).
The windows open as far as the stored position if the current window position is at least 8 Hall pulses above the stored opening position. A window which is less than 8 Hall pulses above the stored opening position, or which is below the stored opening position due to a temporary lowering request, is not actuated.

If closing via the recirculated air switch (N22s2 or N22/7s2) is initiated again during opening before the stored position is reached, then the initially stored position remains stored the motion is reversed directly.
