2008 volvo S80- I keep getting this message recently, all the lights work and everything looks ok. Does anyone know why this warning light/text comes on every once in awhile? Also, my driver's door window made a popping sound when I put it down... Now it won't go up and down correctly. When I put it down, it falls forward and ends with the top left corner of the window making a peak. I took the door panel off and everything looks okay. Is it a motor? The window is still connected to the riser bars.

 

I can comment on the "bulb position failure" light... have you checked to see if all of the bulb connectors are working correctly? Mine had dipped a little bit on the front headlight and had burnt through the connector, all I had to do was strip it down to the wire and connect a new one. Hope that helps...

 

For the window... even though everything looks ok in the pannel the gears to the motor may have messed up. Same thing happened to my 99 t6 on the passenger side. In my experience that means the motor may be messed up.

 

If you are positive that all of the position lights are working, try hitting your tail light assembly a bit and see if any of the bulbs go out. As far as the window it sounds lime the window regulator bent and now needs to to be replaced.

 

I had some bulbs that weren't full bright (rusted/oxidized at connector) and that's why car had bulb warning failure.
