Hi Every now and again whilst putting the passenger window up it would make a really loud bang I thought it was the track that the window slides up and down in so I put a lubricant in the track,but I put the window up yesterday and it gave out a really loud bang its stopped working in the closed position and there is a scratch from top to bottom on the inside of the glass would appreciate any suggestions on which part is broken so that I can order it before I take the door apart or is it a big job that needs to go to a garage its a late 2002 disco 2
Thanks
Thanks
