Hi there

Need to have a look at my windscreen washer system. NOt working front or back. I have cleared the front jets and there was a trickle of water coming from pipes but not much . So not blocked jets. Problem is somewere further down. I want to check the pump. Obviously te fluid reservoir is full up. If I take te wheel off, there is also a panel behind the wheel arch presumably needs removing to get at pump? I can hear a whirring noise when I pull the switch for the washer forward so I am guessing there is power getting to pump. Haven't checked the fuse due to this but will check it anyway. Just really want to know if it is straightforward to access the components and which is the best way? It seems odd that neither my front or back washers are working because it seems unlikely that both front and back pump would have gone at same time. I have checked under car whilst operating and tehre is no puddle so don't think a fluid pipe has split or got disconnected. I am therefore wondering if it is maybe a blocked pipe somewhere or an airlock. Any advice would be appreciated.

Yes there is a panel behind the wheel arch. Removing that should give you access to the pump. To the best of my knowledge there is only one pump serving front and back. The routing is done by an internal slide valve and reversal of the pump motor. The valve has been known to stick but that usually blocks one direction only.

Hi as mentioned you need to take off the wheel arch lining from front drivers side then you will see the plastic reservoir and the pump underneath I believe you just pull it out. It could be that the pump is clogged up and requires cleaning. You should be able to fit a generic pump or get one from ebay or the like.

Can you hear the pump operating? If so you need to check that there is water coming out. The pump could be blocked, the pipe could be leaking, the pipes could be blocked, or the washer jet might need cleaning. I would try the rear jet first with a thin bit of wire. Next I would disconnect the pipe from the back of the washer jet and try again. Easiest things first.
