Power windows won't go up all the way....

    Its a 92 740 wagon. The window goes up to about 1/8 in of the top,
    and then there is a loud clack-clack-clack and vibration. Opened up
    the door and found that the driven arm with gear teeth is is somehow
    out of position, the pinion is going all the way to the last/top
    tooth and just beyond , so at that point it starts slipping, as there
    is not another tooth to engage. Really needs to be fixed because of
    the loud wind noise on the highway. Does motor need to be unmounted
    to be able to re-position the arm one or two teeth further down? Or
    is it the end of the drive arm that has to be disconnected from the
    window? I am not sure how to do either. The motor seems to be
    installed with two rivets. DOn't have a clue how to disconnect the
    arm. Thanks, Geronimo

    Looked closer at the driven arm, and actually the last five teeth (at
    top of arm) are gone. I think a new arm could only be obtained from a
    junked 740, and then there is the extreme difficulty of replacing
    it....so I guess I will just glue a piece of weather stripping into
    the window lip, and live with it. Geronimo

    Hi James,

    I had a 1988, 740 sedan some years ago with power window problems which
    necessitated pulling the mechanism out a couple of times before I had it
    fixed. While a bit of a pain to do, removing the glass etc is no big deal
    and if you can get the new mechanism, it's a pretty straight forward job
    needing no special tools or skills. Just use common sense, don't force
    anything to do with the glass and you'll be ok.

    regards
    Barry

    Extreme difficulty? Replacing the window regulator is not all that hard,
    last one I did took about 20 minutes, hardest part was holding the
    window glass up while I got the new mechanism in place, had I had a
    friend to help out that would have made it easier. A 740T wagon is a
    fantastic car, no reason to ghetto rig it.
