The windows in the 240 wouldn't go up or down last night. I tried the master control on the driver's side and each individual switch, but got nothing. I took apart the relay, no obvious damage. I took apart the driver's side switch, cleaned them all, put it back together and voila, everything was fine.

This morning I rolled the window down on the way to work but when I got to the office and tried to roll it up it wouldn't go. There's a volvo pick n pull nearby so I went over and got a relay, changed it, and still nothing.

I redid the melted window wiring that's behind the dash when I bought the car almost three years ago, and I checked the fuse- it's OK.

Any ideas why they won't work?

What a mess - did it rain?

The fuses on our beloved bricks are subject to looking OK when they are not. Need to at least "rock" the fuse - use a fingertip to rotate the fuse a little with the end points as pivots. The ones with end bits bad will be immediately obvious.

The relay, on the rail under the center dash air vents, is least likely to fail. It engages when the key is in Positon II, and thus allows a heavier current to flow to the main panel on the driver's door. The purpose of the relay is to ensure that a key must be used to operate the windows.

Wiring into the driver's door is a likely culprit. That, and dirt inside the switches themselves.

Good Luck,

Bob

Most likely a corroded fuse. Clean the contacts on all your fuses. The power windows are actually on 2 fuses. The labelled one powers the power window motors. The unlabelled one powers the relay. I can't remember which one it is.

A second cause could be a broken wire in the drivers door hinge. The power to all the windows goes through the drivers door.
