    I have just noticed my windscreen washer isn’t working.
    Pull the lever forward and the wipers activate. so must be getting signal.

    I did change the key switch the other day.
    Everything else seems to be working.

    I can’t see a fuse labeled “washer motor “

    I added water and did notice some water spilling over onto the road?

    Any tips on where to start looking?

    A common problem is the motor just gums up. I have fixed a lot of them by removing the pump and pouring WD40 (or similar) through the inlet. First of all make sure that you have 12v at the pump.

    Barry the motor leaks through the armature seal, replace the pump.

    I haven’t dug around much.

    Yes the tank unbolts and drops down the pump is accessible then.

    I had a similar problem, got on e bay , 17 dollars ,3 days a nice new pump arrived, then the fun of dropping out the washer tank, once you figure out how to rotate in the correct manner ,all good, washing out the tank was most rewarding. almost as good as cleaning the little catch bowl on the air filter.

    You really need to put a meter or a test lamp on it first. It just may save you a lot of work.

    Use a 12v test light from the terminals to earth, there will be power to one.

    Gotta love YouTube geeks.
    Pulled the tank out and saw I had volts at the plug.
    Couldn’t for the life of me work out how to get the pump out.
    Good story on YouTube shows how you “force” it out.
    Thought I would try some WD 40 first and worked a treat.
    The plastic hose was cut off as it wasn’t going anywhere.
    Used some tight fitting fuel hose as a sleeve as the original wasn’t going back no matter how much hot water was applied.

    Anyway, it’s in and running. If it plays up again it’s new pump time.

    Thanks for everyone’s help

    Been thinking about your wiper problem, mine do not act up at highway speed. Perhaps its turbulence form the bull bar and lights, just one of my wild theories :)

    You could be right. But they are the only blades that have done this in 32 years, with no change in bullbar or lights..........And it’s only the drivers side one.

    Might swap the blades over, and see if it happens then on the LH side, to establish whether it’s the blade, or the position. :rolleyes:

    I wouldn’t be concerned....I bought mine from nils around the same time as you and mine are just about worn out now. Have found them to be good at all speeds :)

    Even Nils has inspected mine, along with Luckyphil & Wattie, to try and figure the issue.........and we all drew a blank, as to the cause. o_O

    They do seem to work well for most. :)
