    Front Windows Won't Go Up with the "All Up" Switch, But Work Fine By Themselves

    Hi everyone.

    Wondering if anyone can point me in a direction for troubleshooting this.

    The front windows on my 330Ci convertible won't go up when I use the "all up" switch. They go up completely fine by themselves, and they go down with the "all down" switch.

    When I operate the automatic convertible top, they go down the required amount to lower the top as well.

    So basically, they seem to ONLY not work correctly when using the "all up" button.

    The rear windows go up and down with the "all up" and "all down" switch.

    I read in the manual that they should go up when the switch is used, but I have no idea where to start troubleshooting this. I also read about the "roll the windows down then up and hold the switch" to reset the windows after a loss of power, and I did put a new battery in the car so a loss of power would have occurred, however, this didn't fix the issue.

    It's not really a huge deal, but it seems to be something that's just kind of irritating.

    Any tips would be great.

    Did both windows start doing this at the same time? I would say start with the window switches, but it's very odd for both to fail at the same time.
