Another thing to fix I presume its just a manual pump that operates as you press the button in on the dash (1968 Traveller) - is this located behind the dashboard?

Any tips for repair - or is replacement the only option?

When I put the electric one in mine I had to prime the pump with water by blowing it down from my mouthuntil the impellor/pump had water in it, this is because the pump cant suck on air.
hope this helps

It needs a one way valve at the bottle end of it too

Very often that 'one-way valve' incorporates a little filter screen - which becomes blocked with gunge. Clean it - and test the valve (by sucking/blowing) then try again. If still no go - take the tubes off the jets - and see if water at least comes out the tubes - if yes, then the jets are blocked! Clear them with a pin.

Thanks for your help, its now working. Some idiot had put the one way valve at the bottle end in the wrong way round!

I see !

I'm having this trouble too, and have replaced the in-line one-way valve to no avail. How do I access the jets to take the tubes off, please?

You need to take the glove box liners out.

Try just pricking them with, well 'prickers' as supplied for welding torch etc - or just use a pin!

Thanks for that. I will give it a go!

It can also be worrth while putting a finger over one of the jets and then pumping the washer as this will often clear a blocked jet and then do the same with the other one.
