    12v window leads not hot when engine running

    Howdy,
    I am working around a bad driver side window switch in a 2005 x3 3.0

    I can run the window up and down using a hot lead for battery, charger etc. but the 12v leads that come in to the motor are not hot.

    Should these be hot? Or is there a part of the switch that makes them hot?

    Alternatively is there another easy to access 12v line I can use?
    I am making a 3 way momentary switch so as to avoid spending $280 for a switch from the dealer.

    I researched the issue here and tried the mirror trick etc, the switch is bad.

    Thanks
