Bloody window dropped last night , about half way down,tried to re seat the thing ,went up but that was that ,dropped again,pushed to the top to seal against the elements but that was all I got.#Did a search looks like its the local dealers again,Just had the drains holes done by them as i didnt have the time so that was a £60 job,looks like more bucks on the way 
anyway dragged the father in law out of retirement to sort the window out,not a good idea to watch anyone working on a door panel :!: gotta be a bit rough to get it out.seems the cable had snapped. Bmw water £140 for the internals, got one off eBay for £45.
