Hi all - long time no post i know!
Like many parts of the UK, here at home we've endured temps below freezing for more or less the last week solidly. During this time i've had nothing comming out of my windscreen washer jets - id just assumed it was frozen and that my journey into work (1hr+) was not sufficient to thaw out the bottle (and yes i did check to make sure it was full).

Anyway, today's snow has brought light relief in that the temp is a balmy +2 so i thought it time to double check it all. And still i dont get anything out on the windscreen, although the headlamp washer jets are working.
A quick peek under the bonnet reveals nothing - how on earth can i get access to the pipes to see if they've come away from the jets? Everything looks completely sealed behind a bulkhead of sorts.

Any info would be appreciated.

Cheers

The washer bottle with the pumps in under the O/S/F wheel arch.

Assuming you can hear the pump running when operated.....

Remove the screw holding the mudflap on, and there's also a few more holding the liner on.
Then ease out the wheel arch liner (the side nearest to the drivers door) and you'll find it all there.

Sometimes the hoses have come off of the pump!

I've had blocked washer jets on mine as they are a very fine hole to produce a mist instead of a jet.

To access the washer jets, you need to insert a think flat blade into them, you should see a horizontal line on the jets, thats where they come out from.
there isn't much pipe to play with, and you have to be careful you don't loose the end, so clamp it in some molegrips or similar. Remove the jet and blow through with an airline. Part of the jet (tube) comes aprt to aid cleaning.

If you can't hear the pump running, then it could be a fuse thats gone.

There's 3 fuse boxes to check, one in the cab passenger side, the hidden one under the bonnet nearside behind the ABS unit, and the one on the off side.
Check the fuses and you may find the one thats gone.

They was a thread on this subject, though it may have gone when the forum crashed.

Hope that helps.

Inserting a thin steel rule into the drivers side washer jet:

Note on this second pic (sorry blurred pic) that the jet comes out with the side facing the front of the car first:

And then it pulls out like this:

Its then a simple job to pull the tube off of the jet for cleaning.
Make sure you get plenty of water coming through the tube before refitting - helps clear any **** out of the tubing.

Takes seconds to remove the jets and is quicker to check than going straight to the washer bottle.
If water doesn't come out of the jet tubing then you have to check the pump end.

TIP: Hose down under the wheel arch before you strip to the washer bottle as they'll be loads of crud otherwise!

Thanks for all the replies.

I'd assumed that it was a single pump that handled both the windscreen and the headlamp jets? So with the headlamp jets working then the fuse/pump is okay. If they are different pumps then obviously this is not the case.

I know on my old beemer and audi's that the hoses were always popping off the nozzles so maybe i will take a look at the nozzles first (thanks for the pictures bob).

Sorry I wasn't clear.

There are 2 pumps.

Healamp washers and Windscreen washers.

If you can't hear the pump running when pressing the screen washers, then your pump isn't running!

Check fuses first, then check feed to pump.

Okay - i understand now.
Well i know that the headlamp pump is good, but not sure on the main one.
Its (very) dark and snowing (again) now so it'll have to wait until morning to check fuses.

Thanks again for the info and pics - most helpfull +++

In the old old days of the 70's (yeah I'm dead old) I used to wrap my Saabs washer pipes round the top hose to keep them from freezing most of the time in winter. It also used to heat the washer water which cleaned better. I tried to see if I could do the same with the Nav last winter but can't even find the bloody pipes without dismantling the car. Anybody else tried such a trick on the D40 by extending the plastic pipe and rerouting from under the wheel arch?

I find using decent screenwash stops them from freezing.

although most of the stuff in the UK is ***** stuff - I had full, undiluted containers of the UK stuff freeze to a solid lump of ice when in the alps.

So I bring back supplies from over there every year. don't have a problem now :mrgreen:

By way of an update...
It was the fuse that had blown. Fortunately (for me) there was a spare 10a in the fuse block in the passenger footwell, so it was a simple job in the end.
I did (however) take the liberty of pulling the nozzles out for a good clean (thanks to bob again for the clear pics).

Cheers
