Passenger power windows don't work
'97 Taurus GL 140K miles
My passenger side power windows have worked on and off, and now they are off. Both the front and rear passenger side will not work - not from individual control panels or the driver master. Interestingly, at night, with the lights on, when you press the window buttons, either at each control panel, or at the master, you see my lights dim ever so slightly (I believe this is normal behavior if there were working). This may give a hint as to what is working, or what is not.
Looking at the wiring diagrams I have not idea where to start, except look at the driver master since everything flows through there. The driver main switch was replaced about 5-6 years ago, but who knows it may be bad again.
Otherwise I'm stumped on where to start looking. Your thoughts please.
