Degrading door panel, dismounting front system

Huhu, first of all Merry Christmas to all of you. I have now finally got my doorboards and the ads (Anti – Drön – mats) .. Now I want to build the whole morning .. Now to my questions: – Where are the screws that I have to loosen to get the door panel off? – How do I get the window cranks off? – Would you warm the bitum mats with a hair dryer or rather not? How do you always do that? – How long will I need per door about? Since I don’t have a thread in my search by answering all my questions I now open this one here, I hope this is OK. MFG Martin
