Differences door control units

  • Hello,

    Does anyone know what the differences are between the door control units?

    In our Cayenne, the window regulator does not work on the right front. I once removed the trim and measured current at the connector to the motor. When going up it clicks in the control unit and a minimal current flow comes in, when going down nothing clicks and nothing comes in at all. I concluded that it was probably the ECU.

    Now the question, mine is part number 4H959792P. I have found only 4H959792Mor F. Does anyone know where the differences are there, or if they are interchangeable?
