Also check the wire connections within the door in my case these needed cleaning and WD40, then the window worked again.
At risk of hijacking this thread can I ask about the related problem of noisy window opening/closing. I have lubricated the motor track previously to no avail. The door was crowbarred open once by theives. It was expertly bent back by a bodyshop and looks/works fine but I am wondering if a slight deflection in the angle/curve of the guides could cause a noisy motor?
Cheers
