Who has done it? Was it very difficult? Mine died on my way home today

 

Did mine, it wasn't terribly hard but not a short piece of work either... didnt solve anything for me with one of them though because my problem lies in wiring fml

 

Its kinda like dragracer said, its not god awful but there are easier things to do. Space is so limited and a lot of sharp edges inside the door to scrap the skin off your hands and arms. Just take your time and don't loose your patience.

Lube your tracks and all moving pieces with some good quailty light wieght grease.

Oh yeah, no tricks or shortcuts SORRY. Good Luck
