Where is the P38 windscreen washer pump

[lorkers]

The title says it all - where is the windscreen washer pump on a P38 1999?

When I press the 'wash' button, no water comes out of the nossles - but DOES out of the headlamp washers (if on).

I've traced the tube back from the nosles on the bonnet, and the non-return valve seems to be working, but no water even gets this far... So I guess the split must be where the pump is.

Can anyone point me to the location of the pump to check there?

There are three pumps attached to the windscreen washer bottle. Right hand side from memory. Have a look behind the bumper. The pumps can be replaced individually. They are colour coded I seem to remember. Can't remember which is which but process of elimination should suss it.

Hi

It looks as if it is on the bottom of the reservoir

See attached images from RAVE, well worth getting a copy of it :angel:

Look below the battery from underneath. Not too hard to access.

Pumps just push into the bottle with an O ring to seal.

Thank you!

I know what I'll be doing this weekend.

I'll report back if I ever manage to wash my windscreen again...

Well, two weekends of struggling with it, and still no water.

Should anyone be tempted to 'try this at home', just a warning that there are three pumps at the front of the reservoir - and every one is ever so slightly different. Slightly different tube fittings, but plug compatible electrics.

My plan initially was to swap over the (useable) headlamp pump with the (dead) windscreen pump.

No joy. Tubes are the wrong size.

And now, for some totally unfathomable reason, I can't get the middle pump back in that operates the headlamp washers. Just won't push into the O ring.

Still - I'm waiting for a replacement pump from the UK, and when I get one I'll strip down the whole reservoir to fit both back, and work out what's wrong.

Sigh.

Why are P38 never straight forward?!?

[lorkers]

Finally! Water! In the never ending desert!

Should anyone be tempted to 'try this at home' can I suggest that instead of

jacking up the P38
removing the wheel liner
removing the bolts from the reservoir
taking of the tubes
dropping it down
inserting a new pump


A MUCH easier way to get at it, is to take out the front fog light - it's only four screws, and the three pumps are lined up behind it, here:

And with one push, my problem of slotting the pump into place was solved.

Hurrah! I can now wash the windscreen from inside the car!

Hi

Great method for gaining access here !

Well spotted :D

That's a great tip, thanks for that.
I just replaced the low screen wash sensor in mine, I would say you'd probably still have to go in the long way to get to the sensor, which is positioned above the three pumps and may not be acsessible from the fog light hole, but this is a great way to do the pumps.

Thanks mate.
Just when I thought I should spend less time on the rangey, I now have a good excuse to tackle my rear window washer.
Too good! :D

Mine, too!

I finally got around to tackling mine today while I was swapping the front bumper. The pump worked so I tried blowing out the water line with compressed air.

That was a mistake. It's blown the line off a connector somewhere in the left rear quarter - I can hear the air when the line is pressurised. :(

I'll be taking the covers off there tomorrow! :D

I'm not too sure with the P38 but some LRs have a valve in the rear pillar/roof area to stop washer fluid dripping out of the jet on acceleration so that could well have blown a hose off.

[p38arover]

Yes, looking at RAVE, there is an NRV in the rear quarter. I'll pull that panel out tomorrow as I want to replace it with a spare from the other car.

I think I saw an NRV on the floor in the back of your spares car yesterday......

I think I saw an NRV on the floor in the back of your spares car yesterday......I'll have to make sure it's still there then :twisted:.

[p38arover]

Fixed.

The hose had blown off the NRV when I put air pressure into the water line at the pump.

It took quite a while to find the blown off line in the rear pillar. (Disregard the felt pen markings they were there.)

I had to remove the nozzle in the tailgate as it was blocked (and quite badly). It's a pig to get to with big hands. If you ever remove it, be careful the hose doesn't pull back into the tailgate.
