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.

Overview: How to change the distributor cap and rotor on a 1997 Volvo 850 GLT.

This job requires removal of the battery and then the bottom half of the air filter box in order to reach the bottom screw on the distributor cap. Including taking the photos, the whole job of removal and replacement took 2 hours (first time).

1) Common tools: a standard screwdriver for the distributor cap screws and a wrench or socket to disconnect the battery terminals.

Less common tools: You will need a 3mm hex key (pictured below left) for the rotor and a slim ratcheting driver with Torx bit (pictured below right) for the vacuum switch.
