E51 Elgrand sunroof problems + Fix!

This car came to me with the sunroof stuck open. Upon inspection there were a number of faults contributing to the bad operation of the glass, all of which are fixed in this video. I'm not sure what the original cause was but I suspect it was a cascade type failure where one initial fault led to many others in time. Cleaning products from: Www.car-couture.co.uk
