    Passenger window......When I try to close the window with drivers side switch, the windows hits the top then automatically reverses, and stops halfway. If I close it with the passenger switch, it remains closed. Any ideas? Possible Possession from Demons?

    Try this:
    Using the driver's switch, close the passenger side window and keep holding the switch for a few seconds (4-6) after the window closes.
    Repeat when opening the window.
    Now try closing the window without holding the switch.

    Took WAY too much digging, in the Repair Manual. This should be in the Owners Manual, it's a common issue:

    • When a power window regulator or a power window regulator motor assembly is replaced, the power window control system must be initialized.

    • After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operation at least 5 times:

    a. Close the power window by fully pulling up the multiplex network master switch assembly or power window regulator switch assembly and holding it at the auto up position.

    b. Open the power window by fully pushing down the multiplex network master switch assembly or power window regulator switch assembly.

    • The jam protection function may operate unexpectedly even when the power window control system is normal due to detection of a value different from the operation learned value when the door glass moving speed changes sharply under any of the following conditions:

    a. A power window is being opened or closed while the vehicle is driven on a rough road.


    b. A power window is being opened or closed while the door is being opened or closed.

    c. The voltage changes abruptly.

    Thank you for your suggestions. Seems to have "cured" itself. But I wonder for how long?

    Probably for good, at least 'till another 12 volt disconnect. You'ld think they could put a small flash drive in, for stuff like this. Anyway: once learned it seems to stay learned.
