In my car, the rear passenger-side window will not go up from the switch on the driver's door, goes down fine. Any ideas on that one? If I have to remove the driver's or rear door panel to trouble-shoot, is there a special tool/procedure required to do so?
ANy of your expert opinions are greatly appreciated.

If so it's the "switch pack", which Volvo dealers replace as a unit.

Stage One is to remove the switch and try taking the switch apart and cleaning the contacts with that pricey Radio Shack contact cleaner. If you're ambitious or cheap, try this first.

Stage Two, if Stage One doesn't work or cost is no object, is to replace the switch pack. (It's expensive, so I'd try Stage One first.)

I keep a small can of the contact cleaner in my car, I feel it's as essential a Volvo tool as the Mini-Mag Lite.

Thanks for the quick response!
Yes it does go up from it's own switch. Do I have to remove the whole door panel to get to the $181.00 switch pack, and is there any special tools or tricks to do so?

This would be a warranty item if you have the extended warranty.....

I've not actually done this without removing the door panel for other reasons ... but I think the switch pack is just snapped in. The reason I think this is that on a rainy day I did see an S70 in my dealer's service lane with duct tape and plastic covering the open driver's window and the switch pack had been removed but the door panel was still in place. I'd first try finessing it with a small screwdriver or putty knife covered with masking tape.

If you DO actually need to take the door panel off, there is a TORX screw right behind the small cover plate in the door handle in the armrest, this plate is pried out with a small flat screwdriver blade, then undo the screw. Pull the trim piece behind the mirror towards the interior, it's also just snapped there. The door panel is fastened on the bottom front and rear with a bunch of reusable bayonet fasteners, if you're careful you can pull the door panel out without breaking any, I used a medium-width putty knife covered with masking tape as a tool. There is also a lip next to the window, the door panel snaps into this ridge, you push the panel up to un-do this, having the window open helps. This is really a lot less complicated than it sounds.

If the Radio Shack method doesn't work and you do go for a new switch pack, try the Volvo parts discounters, such as Volvo of Houston (800-468-0041), FCP Groton, All OEM Volvo Parts and Verrigni Marine. See the pull-down menu above.

A similar thread from the Brickboard archives: HERE. This is not at all uncommon.

It is a snap in switch pack for 98 XC. I removed it before. All you need to do is to pry it out carefully. The pastic is faily soft. Use cloth to cover your hard tool or us a softer tool.
