Default Does a windscreen washer pump need to be primed?

Scrabbling about under the wife's Xantia on Saturday, washer pump not working. It seems to go round but nowt comes out
It's one with two outlets, the REAR one works OK.
Swapped it out for a new used one from a scrappy and got the same.

I've now ordered a brand spanker off e-bay, but it later occurred to me that maybe I should have SUCKED the fluid through it to prime it?

Have you tryed un pluging your washer pipes before your washer jets to see if there blocked.Some cars have a filter check thats not blocked if it has one.

Thanks Paul.
Yes, I've done that Skinner, I replaced all the pipework and non return valve too as I couldn't either get to it, or clean it out, so re-routed it with new stuff. Jets have been cleaned too, but the pump wasn't even lifting water up a pipe, let alone out through the jets

Really should not need to, only other reason I can think of is the the pump might be sucking air instead of water because of an air leak between the water bottle and the pump. Or even a soft pipe which is getting sucked flat and stopping the water flow into the pump.

No, it can't be that, the pump, like the one on the Scoob, fits directly into the washer bottle via a soft rubber grommet that acts as a seal.

That's why, every time I remove it, I end up wet through with a stream of windscreen washer fluid up my arm

Nah, stupid thing came this morning while I was out, needed a signature so they took it back again.

By the time I got ythe car back after it's oil change, the PO was shut.......what sort of hours are those? Lazy barstewards.

Should be able to get the youth to take me up to get it tomorrow, then fit it tomorrow night, all being well.

Yes all understood. I imagine you must have checked the inlet to the pump for something blocking it. Could you feel any suction on your finger if you run the pump while disconnected from the bottle?

Hope the new one works if all else fails anyway.

Default Well, it's fixed!

Finally: new pump, new piping throughout, new non-return valve, and away it went..........
but NOT before I'd discovered that the new pump ran in reverse: it washed the rear windscreen when I started the front wipers, and vice-versa.

So the stupid thing ended up off AGAIN to replace pipework the opposite way round.

French cars! ;rolleyes:

Glad you got it sorted, my old pug 406 used to drive me mad, little room to work on anything and pricey parts, whenever i fixed one thing i usually ended up having to buy associated bits
