Heard a very loud snap from within the door cavity this morning about half way through the "one-shot" descent cycle of the driver's door window. All glass remained fully intact and I was able to manually pull the glass back-up to the shut position, so at least I could get back home without freezing to death!!
Have removed door panel, door airbag and inner polystyrene membrane (the one attached with the butyl bead) and can now see that the wire cable has snapped. Have now run out of light for the evening, but will resume in the morning. Has anyone come across this before and, if so, what is the best way to progress from here?
