Can anyone help with my electrical problem?
When I attempt to lower the drivers window the sunroof opens aswell, and the same aplies to the sunroof, the drivers window goes down aswell.

Are the windows fused separately, left and right sides?
Try removing the fuse from one of them and see what happens then.

I would go for a fuse box problem or that the wires have become frayed and are touching each other

I believe it depends on the model year of the car - earlier cars have a relay & fuse for the windows and a separate fuse for the sunroof, later cars have a combined window/sunroof regulator that uses a single fuse.

Hi

This sounds like a relay problem to me...

Temporarily swap it for another on the fuse/relay board and see...(most are the same)

All the best Brett

Thanks for the advice guys, I'll swap the relay once I find which one it is.

I have traced the reason why to the black relay box under the passengers seat, when I was clearing up some old wiring I connected a plug that looked like it had worked itself loose, I should have left it as it was. Anyway I've dissconnected it now and the sunroof and window work as they should do.
