It has a safety switch to prevent idiots from closing the windows on
their throats.  (I propose that Darwin should rule, but Toyota differs
with me.)

The safety switch is failing.  I don't know if the sensor is in the
motor itself or is elsewhere.  If it's the motor, it's expensive.

As Elmo pointed out, the windows with auto-up feature have a safety circuit
to prevent injury from entrapment in the window, although it is not really a
switch.  The system monitors current draw in the motors and reverses
direction if current draw is too high.  Make sure that the window tracks are
free from dirt, debris, and obstructions and the weather-stripping is not
too tight against the glass.  You can try spraying silicone lube on the
window tracks, and if that doesn't work, then the shop will have to check
the motor and regulator.

Try pulling the switch up partway instead of engaging the auto up feature to
get the window closed.
