    Now working with 2 speeds!
    Think there may be an issue with the switch….. everything works fine until I put the switch in the housing and tighten the screws that hold it.
    Then fast speed disappears….if I slacken one of the screws, just a bit, then two speeds return.
    It all back together and I have two speeds and unusually for me, I don’t appear to have created another problem.
    Only logical conclusion regarding tight/slack screw is earthing?
    Anyway, for now, all’s right with the world.

  2. Unlikely to be anything to do with earthing (which the switch doesn't need). More likely a wobbly contact in the switch.

    Did have a bit a rattle, which stopped when I pulled it out to have a look, but nothing fell out.

    It could be that the metal body of the switch is not properly gripping the plastic panel with the switch contacts mounted on it..
    Or the screws are too long and blocking the switch movement to the fast position by acting as an accidental end stop for the switch.
    I seem to remember the screws are quite short. 20240428_190200.jpg

    The screws in mine are longer than that, about half the length of a domestic plug fixing screw. The indicator side has a couple of random ones that fit.

    Well, having had to actually use my wipers on a holiday a couple of weeks ago, I can safely say that intermittent wipe is best invention since sliced bread ( not literally, obviously.)
    Did notice that the wipers “park” in what I consider the correct position, but when wiping, actually go lower than the park position, but don’t actually hit the window seal.
    Is it possible to fine tune the positioning?
    Also, towards the end of the holiday, the offside linkage developed a knock from behind the dash….. that spindle seemed to have more play in it than the other…. is a new spindle in order, or could it be the wiper motor’s position that’s causing it?

    Try doing the nut up on the outside - that could be loose.

  9. I'd suggest you didn't set set the park position correctly.

    When I get her back from the welder, I’ll re-read your instructions and have another go.

    My offside wiper has more slop than the nearside- on mine its some nylon bushings in the linkage are a bit worn.

    And mine clanks internally against some PO added metal where they welded a patch with a flange that the wiper mechanism just clips..
