lawser Posted February 6, 2009 Posted February 6, 2009 Hi folks, Rear wiper washer has stopped working, wipes ok but can't get any water to flow !Windscreen washers on front wash wipe ok, could it be the pump ?As i understand it it's just one pump for both ?Would this be a good time to buy that Haynes manual then ? :unsure: cheers, lawser Quote
Randombloke Posted February 6, 2009 Posted February 6, 2009 Rear wiper washer has stopped working, wipes ok but can't get any water to flow !Windscreen washers on front wash wipe ok, could it be the pump ? More likely to be a blockage in the jet that directs water onto the rear screen. This is a very cheap or free fix so try this first. It is possible to get the plastic insert out without undoing anything, but I forget how. Will have a look and post photos if you get stuck. I think it involves using a very thin screwdriver at one end of the oval or the other. Get the plastic insert out, detach the hose from the rear and then test the washer. If it goes, a swift clean out has you sorted. If not, then from memory the pump goes one way to drive the front washer, and the other way to drive the rear. Have someone operate the rear washer whilst you listen in the drivers side front wheel arch. If you cannot hear the pump running, then this may be the fault, but it could be the stalk...... The pump lives in the wheel arch and is a little bit of a pain to remove, so eliminate all the cheapest options first. Quote

Then listened for the pump as you suggested....pump sounds as though it's operating correctly !I guess the next thing is to have a look at the pump ? Cheers, lawser Quote

If the pump is running when the rear washer is selected on the stalk then it could be the pump is not working properly (but still running) or a hose has become detached or blocked somewhere. Might be worth connecting up a bike pump or simply blowing back down the tube, but gently. If there is a blockage you will know, if there is a leak then an accomplice will be able to verify that there are no bubbles heard in the washer fluid tank..... this may also have the effect of clearing the blockage...... I think you'll have to look in the wheel arch now but faced with removing the bumper and trim I gave the job to my local indy..... Quote

Thanks Randombloke....I thought i might try blowing down the rear washer to see what happens ? Cheers, lawser Quote
myglaren Posted February 8, 2009 Posted February 8, 2009 Mine doesn't work either, for some time now.When selected on the stalk, the windscreen washer operates instead (but not the wipers :unsure: ). There is a flapper valve in the pump that supposedly helps direct the flow where it is meant to be going. It has been said that non-Citroen washer fluid degrades the valves and causes just this problem. A new pump is about £12 and a few grazed knuckles. What the washer fluid costs is anybody's guess.
