Mine have given up the ghost, fuse is OK. Can't quite see how they work, is there some central compressor and just piped water to the pop up bits?
Anyone have a diagram? Thanks Olly
We had this on my wife's W209. The pump was the culprit, so it was replaced. A common fault apparently predominantly becasue of where it is located in the wheelarch/wing.
Hi,
well I lassoed the squirt bits and pull them on out a few times with a good squirt of WD40 but it's still as dead as a dodo (and the pump makes no noise)
Could anyone please give me abit more info on where it's located / how to remove it?
The pump for the headlamp washers is in the bottom of the windscreen washer bottle.
The pump (the white one!) is a pushfit into the bottom of the bottle, you get to it by removing a cover at the front of the nearside wheelarch, as though you are going to replace the lower driving lamp bulb
My pump was a pattern part and was £20 from an internet dealer - forgotten who.
sorry - was off line for a loooong time.
just to add... I was able to resurrect my pump with copious manual rotation through the little holes and wd40. Just basically needed to get all the mud out of it!
