    Sticky slow windows this is a quick how to - nine times out of ten it will be the window runners will need some grease this can be a 10 minute job if you follow this quick guide .
    First pop out the mirror adjuster this is done with a small screw driver then pull the electrical block off,now remove the trim around the door pull by pushing it forward .
    Behind the mirror adjuster there is a small star head screw remove this .
    Now the door card is just held on with plastic clips feel your way around the door card until you find a tight spot and then pull ,do this all round the sides and bottom

    Right now for the top tip ! do not remove the door card from the top,but just pull it forward at the bottom there is some foam backing this can be pulled away its only stuck on. The reason for not removing the whole door card is because it can be a real pain to refit at the top with the door pin and rubber seal.
    With the door card pulled forward, you can see the window runner, slap a load of copper slip on, then run the window up and down so you can see where the grease needs to,go job done .Reverse the steps to put the door card on.

    This is a useful tip Si. Thanks for taking the time to post it :-bd

    Just one thing to note - the foam backing is a "Vapour Check Membrane" :-!
    If it is not properly resealed along the bottom edge it *can* lead to water ingress.
    I don't believe this to be a major problem on Zeds but it can be a real pain on 3 and 5 series cars (been there, and got the T-shirt) ;)

    Another quick tip in this is to spray all the runners with wd40 while moving it up and down first

    this will remove all the old grease allowing you to put on fresh grease that will then last longer

    A lot of people think WD40 is a lubricant
    it was made as cleaner, you clever boys already know that ;)
    They spray things and wonder why they sqeak after a short time :D

    Actially it was the 40th test formulation for a water displacement spray......
    If you read the Ronseal bit it will tell you
    It does have short term lubricative qualities but is a far better solvent especially for sticky label residue.

    WD 40 is also great for getting road tar of paint work
