Braymond 4 Posted February 19, 2019 Doesn't appear to be working this week? Whats the first thing to check? The res is full, its not frozen, the is no pump noise when trying to spray. Maybe a fuse?? Some kind of damage when it was frozen a few weeks back (when it was working) Share this post Link to post Share on other sites

Braymond 4 Posted February 19, 2019 Thanks Tom I've got a multimeter I've never used - what specifically do I need to do to check the above? Share this post Link to post Share on other sites
Ozymandis 96 Posted February 19, 2019 Set meter to DC volts Take off washer motor plug Put one probe in each terminal of the plug Have a glamorous assistant operate washer stalk See if you have 12 volts. If not then check to see if the positive or the earth is at fault Put one probe on one terminal in plug Other probe to battery negative or good earth Have assistant operate stalk see if you get 12volts If not swap the plug`s probe to the other terminal in the plug and try again. if no 12volts then its, a positive supply problem, eg fuse, switch or a wiring problem. set meter to ohms or continuity one probe to negative or a good earth other to each terminal in plug in turn one terminal should give a very low or even zero resistance to earth If not then its an earth fault. My experience is the plugs corrode, water wicks up the wires and they go black and manky internally. Chop off a few inches of the wire and join fresh wire to the good bit you cut back to if this is the case, and put some individual connectors on instead of the green and manky corroded plug. Sometimes when you take the plug off and put it back on a few times it cleans it up to work for a while get your assistant to hold the stalk on whilst you tug the plug off and push it on a few times 1 Share this post Link to post Share on other sites

Rob_the_Sparky 9 Posted April 30, 2019 On my car it was the washer pump, simple fix but had to make up a little extension to the harness as the replacements seem to have the connector pointing up rather than down and it is not long enough to connect.
