Windows going up and down ok except for one that will not always go up? It might be a VERY easy fix, detailed in the Volvo Forum tutorial. All you need is a small amount of technical skill. And a toothbrush.
medic225 » I was having problems with the power window switch not working on my 2000 V70. Most windows worked fine except one that would not roll up using the driver door switch. That window worked fine using the switch on its door. I was able to take it apart, clean and reassemble the driver door switch and now it works.
Here is what I did:
First remove the switch from the door. Insert a small flat blade screw driver between switch and door panel and pry up gently and the switch will pop free of the door. You may notice in the pictures that I removed the door panel from my door but that is not necessary to do this repair. Then remove the 3 electrical connections from the bottom of switch by depressing release tabs on side of connectors and pull out connector.
Now take the switch to a clean work area then using a small flat screwdriver pry off the grey trim piece from the top of the switch. There are 3 tabs on each side and one tab on each end.
Optional: give the trim piece a good cleaning with soap and water
Set aside the trim piece and now lets open the switch assembly. It has 3 tabs on each side and one on each end. I used a thin knife blade to release each tab and then inserted a toothpick into the tab to keep it from re-locking while I worked on the next tab.
Here it is opened up. You can give the top piece a wash with soap and water is you wish. Don’t use water on the bottom piece.
The brass spring fingers are the contacts for the window switch. This is what we need to clean. I used a toothpick wet with some electrical contact cleaner to clean at the contact point of each brass finger. Do not bend the brass fingers just lift them enough to get your toothpick under them. Don’t go after the contacts with sandpaper or you will be buying a new switch soon.
Here is what was under mine.
Now I brushed off the inside of the switch assembly with a dry soft toothbrush Now time to reassemble the switch. Turn the contact assembly and the plastic switches upside down during reassembly. This allows the plastic switches to hang down during reassembly and they will slip into the proper position when the parts are pressed together. When all the switches are lined up then just a little pressure will re-engage the tabs. Test the switches for normal movement. If the switches wont move then take it back apart and try again.
Now you can put the grey trim piece back on and go back to the car. Reconnect the electrical plugs and test each window.
I hope this fixes your problem like it did mine.

Bonus! More on the Volvo V70
Late in 1996, Volvo introduced a new estate car to the market, the V70.
The Volvo V70 was developed from the concept of the successful 850 Estate which had then been on the market since February 1993.
The exterior of the new V70 showed softer styling than its predecessor, but still carried a strong Volvo identity including the typical almost vertical rear end. Inside the car, the dashboard was new, as was most of the interior. As regards safety, a number of important improvements were also made.
An interesting and successful addition to the V70 models was the all-wheel drive XC 70 models.
The Volvo V70 was produced until 2000, when it was replaced by the second-generation V70.
