I've searched high & low trying to find an answer with no luck. I have a 95 e320 sedan and the other day all 4 windows & sunroof stopped working. Everything else is fine, ie; wiper, mirrors, pwr seat rear defrost. When I hit any switch, I can hear the relays under the rear seat behind the driver click, but the windows don't go down. I replaced the fuses with no change, switched around the 2 fused relays that are under the cover behind the fuse box under the hood on the drivers side with no change, I pulled the rear seat out and took a look at things, but in all honesty don't really know what I sould be looking at so I sort of tapped things with the end of a screw driver lol.

The other day I tried the switch while driving and the windows worked, but then after I did them up, they wouldn't work again.

Any advice would be greatly appreciated.

It may be a wiring issue that is allowing an intermittent connection.
