software fix to window switch problems?

I have a problem with my 99 V70 driver window not going up. After
having the dealer and then one shop replace the bank of switches at
great expense, I discovered that the problem would mysteriously solve
itself after a random period of time. This has been going on for
several years and it does not behave like a dirty switch - no periods
where it works only some of the time. Since the switch is on the
handle of the door with the problem window it is not a pinched wire.
Plugging and unplugging the wires does not help. Several posts around
the web allude to a software problem and one claims that one can reset
the thing oneself but there is no link and no contact information.

Any ideas how to reset/reboot the thing? (local mechanics and dealer
are useless and would just like to sell me a third new one).

Thanks so much. Did I mention that the rainy season has started here?

 

That software stuff only applies to the new body models, the "non Volvo
shape" ones, i.e. S80, new style V70, S60 etc. All the windows (and the
sunroof) are protected by an automatically resetting circuit breaker,
but if this is a problem then all windows wouldn't work at the same
time. There's not really much that could cause an intermittent problem
with the driver's window (while the others are all working) other than
the switch. Obviously, there's a connection between the switch and
motor, and it's possible there's a problem with the motor, although I've
never heard of an intermittent motor.
