Does anyone know how the end of travel/position sensing is done on the automatic closing/lazy locking, drivers window of an 827. ie does the motor output pulses which the controller counts, or does it simply sense the current in the motor. If the latter, has anyone repaired the sensor circuit of one of these? Is it possible to reset the computer setting the sense values without disconnecting the 12V supply? Does disconnecting the supply reset the computer? Regards Capitol
