    In the past few days,
    -Every time you want to adjust the windows in any seat, you have to press the button twice. Holding it does not work either, it has to be pressed once, then it will work the second press. The responsiveness period is maybe 5 seconds of INACTIVITY (will remain functional if you keep adjusting them), then you have to do this again.
    -I can roll down the window on driver's side, NO auto.
    -I can adjust the mirrors.
    -Each seat can adjust its own window (regardless of the master lock setting), WITH auto.
    -I cannot lock the doors.
    -Passenger can lock the doors.
    -Both rear windows almost sound like the motor is low on power.

    First stop, what fuse should I be looking for?

    Hey, did you ever get this solved? Just happened to me; fine last night, but not working in the morning.

    Sorry for the late reply: No, I never did. Just been dealing with it since.

    Appreciate the reply, and not that this is still a high priority for me but are you sure?

    I have no idea why I neglected to mention in the original post that a week before it started happening, I left my driver side window open when it rained.

    So you almost certainly got water into the madter switch assembly, and possibly anything else in the door.

    no, i am not sure. pretty difficult to hard diagnose over the internet.

    i would agree with guy, looks like the source of the problem. but then again, i'm not sure.
