Hello, can anyone provide me with a step by step guide on how to replace the window regulator on an audi a6 window, i would take it to audi but they want to charge me way over 拢300 i have another regulator but im just not sure on how to replace it.|||remove the door card and insulation and it is a straight unbolt and remove replace and bolt up procedure, the door cards come off easily IF you undo the right screws and remove it in the RIGHT order, first check the wire into the door hasn't come unplugged or pinched(rubber bellows)
