Windscreen nozzles.

[keith reed]

I have been having problems with windscreen nozzles on the vh. new nozzles motor and lines. To be quite honest I could piss faster. No amount of adjusting seems to make any difference. i have tried the same nozzles on the vs with the same results. Any ideas anyone?

Open them up.

Could you check you are actually getting the full 12V at the windscreen wiper nozzles....This might be a cause why you have SFA pressure...

Is there a mesh screen filter on the washer bottle . My wife and daughter had similar problems with their Hyundai i20s. Turns out they have a small piece of mesh to filter out the crap and it gets clogged with what looked like slime or algea.had virtually no water pressure

You can try to flush the lines with vinegar to get any limescale out and install an inline fine mesh filter.

I had the same problem with the R8 I once owned. I cleaned out the filter and was all good again. With the vh everything is new. One nozzle on the vs blocks, it is clear at the moment.

I am only running a mixture of vinegar and water in the washer bottle.

Thanks vc I'll give that ago. Would part of the problem be dual nozzles rather than single? Also I have tried these nozzles on the vs and they no matter what I do to them they aren't much good. The ones on the vs when they are running properly and it's only the right one that plays up are fantastic.

Couldn't say mate.....Was just going off a problem I had with an electric fuel pump where I had a bad power connection with it causing bad pressure problems.....So thought I'd make a similar suggestion with your wiper pump.

Process of elimination. If you disconnect the washer reservoir pump from the tubing does it pump well? If so is there a blockage in the tubing you can clear when you disconnect the tubing? If the tubing is clear and the pump is pushing fluid well then the only place left would be the nozzles?
