Window Switch Problems

[hbn61013]

Hi,

I have a 2005 BMW X3, and lately, my window switch panel has been acting up. All windows work fine when closing and opening, however whenever I roll up the driver side window, the rear passenger side window or the rear driver side window would sometimes open a quarter of the way. Before I start spending money on replacing the switches or before I bring it to a dealer/indy shop and pay, are there things I can do myself to isolate the problem and possibly find a solution? Could a short circuit be causing this, even though everything works? Could it be just a malfunctioning switch? I don't have any blown fuses. Is there a relay for the window switch, if so, could it be bad? Has anyone else had this same problem? I used the searched button, but didn't find anything.

I would appreciate and suggestions.

thank you,
