GF72.29-P-3013RT Power Window Raising/Lowering, Function
- up to model year 08

Component Identification:

Function requirements
^ Circuit 15 On or circuit 15R On
^ No overvoltage or undervoltage
^ Not active for rear power window child safety lock
^ For automatic raising or lowering additionally normalized power windows.

The power window can be actuated up to 5 min. after circuit 15R or circuit 15 Off, if the front doors are not open.

Driver control point
All front door and rear door windows and the vent windows can be opened and closed using the driver power window and outside mirror adjustment switch group. For manual raising or lowering, it is necessary to actuate and hold down the corresponding switch on the driver power window and outside mirror adjustment switch group up to the catch point in the opening or closing direction.

For automatic raising or lowering, shortly press corresponding switch on driver power window and outside mirror adjustment switch group beyond the catch point in the opening or closing direction.
Actuation is performed until the position recognition detects that the windows are opened or closed.
When the driver power window and outside mirror adjustment switch group is actuated, the left front door control unit is read in via the LIN-BUS and the corresponding message is relayed to the right front door control unit and the front SAM control unit via CAN-BUS.
Then both door control units actuate the left front power window motor and right front power window motor.The front SAM control unit actuates the left rear power window motor and right rear power window motor as well as the left and right vent windows.

Passenger control points and rear control points
Only the associated window can be opened or closed by the front passenger power window switch or the rear power window switch. Press passenger power window switch or corresponding rear power window switch in the opening or closing direction for manual raising or lowering.
Momentarily actuate passenger power window switch or corresponding rear power window switch beyond the catch point in the opening or closing direction for automatic raising or lowering until the position recognition detects complete opening or closing the window.

Actuation of the front passenger power window switch or the corresponding rear power window switch is read in, voltage-coded, by the corresponding left front door control unit and front SAM control unit which directly actuates the corresponding power window motor

Function abort
^ If the corresponding control switch is actuated again
^ If the excess force limiter is actuated during automatic raising
^ If function prerequisites are not fulfilled
^ If Hall sensor defective recognized
^ If corresponding vent window switch released.

The excess force limiter is activated on the side windows only during automatic raising.The vent window excess force limiter is realized via the left/right vent window obstruction sensor strips.

Child safety function
The function of the rear control points can be disabled with the child safety lock switch in the driver power window and outside mirror adjustment switch group. Already performed actions are interrupted immediately by the rear power window switch when the child safety function is activated The current status is recognized by the child safety lock indicator lamp and the current position of the child safety switch in the driver power window and outside mirror adjustment switch group.

Vent window play protection
The play protection is activated if the vent window motor is actuated more than 10 times within one ignition cycle.However, the vent windows can still be closed.

Sequence of priority
The driver power window and outside mirror adjustment switch group has the master function.An adjustment request via the front passenger control point or rear control points is interrupted by a corresponding actuation of the driver power window and outside mirror adjustment switch group.
