yes button lights up....fuses are OK ...
When I take electrical tester and connect one end to window wires, and the other end to metal where back door locks down, electric tester light up..
So I guess that wire from the window that is connected to the ground lost contact somwhere, but I cant see where that wire goes after where is connected to the window.
