    Hi All,

    I am new to this forum stuff so i apologise if this question has been asked and answered previously.
    My CLK has had a roof pump problem for some time now and I am hoping that someone may have had similar issues.
    Basically the roof pump burnt out and so I replaced it and that one burnt out too! I was told that the relay was at fault so I replace that as well.
    Now, I would like to know if there is anyone out there who can tell me what the 2 additional wires coming from the electric motor are for other than the power and ground wires as i have another motor i can fir but it only has the two power wires.

    looking at the wiring diagram, 2 wires only for the motor. This is fed power from the relay and there are 2 wires that are connected between an overload thermocouple and the roof controller.
