I got an email from a MVS reader a few days ago:

Hi Matt,
I recently modified my 1998 V70 so that the drivers side window switch would last a long time. My switch had failed due to an arcing contact. I repaired to contact and then added an extra circuit to reduce the switch current from 16 amps to .001 amps.

I though you may like to include a link on your web site.

Thanks for letting the Volvo community know about this, Richard. How very industrious of you!

The repair is of course on a V70, but the concept will transfer to other models.
