    My mechanic gave me the driver side window switch from eater v70 or s70 to
    have a look at. I pried it open and this is what I found.

    It appears the there is partial vacuum created inside the door panel and lot
    of lint gets sucked into overly delicate switch mechanism. Intermittent
    operation results. Contaminated contacts arc and overheat the delicate reed
    which partially melts the plastic (orange) cam actuator. Not a pretty
    picture.

    I stick with my 91 740. The switches are much easier to clean.
