[928uk] Wiper stalk gone a bit wobbly

[Paul R Smith]

For cleaning, probably safer, as it will be designed not to attack 
plastic. The mechanism still needs some lubrication afterwards.

Electrical contact cleaner spray would be a better bet I think.

    Probably there is some grease in the mechanism which has dried out and
    become stiff, which has then softened with warmth.

    What you want is something in an aerosol which will wash out the old
    grease, lubricate the mechanism and not act as an insulator on the
    contacts. Maybe brake cleaner followed by "electrical contact grease".
    Do not use carb cleaner, that will dissolve lots of types of plastic.

    Note, the above could leave you with a switch that doesn't work at all,
    it's not a recommendation, just ideas.

    Hi

    Something strange has happened, the whole indicator unit has been
    indoors in the warm today and the wiper function now appears to be
    working ok. It had been on the car in the cold outside so perhaps
    that had something to do with it.

    Cheers
    Pete

    Hi Peter.
    They do that sir!
        it could well be that part of the stalk inside the housing is
    broken.
    Also doed/did the stalk self centre? Th tab which facilitates this
    wears and self centering stops working. I have had some new parts 3d
    printed - I have sent a few out for people to try and had no
    feedback that they have failed so I can only assume that they work fine.
    You can drill the rivets out and replace them with self tappers,
    however the unit has many fine springs and some ball bearings so you
    need to be very careful, take pictures and dismanlte it in a lrge
    bicuit tin!
    If you don't feel capable send it to me and I will do it

    Regards
    Richard
