Rear window washer spray pattern
 

Is it supposed to be a fan spray with a wide pattern?

mine dribbles the water/fluid... like opening the garden hose

Mines just a single squirt/stream to above the wiper - and the wiper action is delayed for about 1 second after the stream starts. No fan pattern.

Wish mine even worked.

ugh.....mine is clogged....need to see what's wrong now.

Mine gets a few inches of fan and a lot of limp-hose dribble. My previous e53 was exactly the same.

Yeap same hear for mine, works but a single squirt/stream. But certainly no pretty fan pattern, disco lights or fireworks. Perhaps I should look into making washing the rear window whilst driving more of an event. ;)

so funny this has come up, have been pondering and wondering about it for a while. Keep meaning to stick a needle or something in there and try to clean it so it isn't just a dribble

This happend to mine... then I change the rear wiper to an 18in and it cleans the window w/o skipping.

I think the problem with the rear wiper is that often the in-line check valve gets clogged but even a new check valve seems pretty restrictive and only allows a squirt of fluid rather than a spray.

I never use the rear wiper/washer to clean the window, don't want to risk scratching it, not enough fluid comes out even when it is in tip top shape. I don't even use the wiper when it rains, just let Rain-x do the work. It doesn't clear much of the glass anyway.

I use mine to keep it clean more than free of rain. My rear window goes from pristine to filthy in the time it takes to put away the glass cleaner.

when the blade is not touching at the top - spray that fat spring and surrounding parts with penetrating or lubricating oil. When you don't use it enough it gets too comfortable in its parked position and doesn't conform to the window.

Question to those that the rear wiper are not working... is your washer working? On my 3.0 X5 it's 2001... the washer or the wiper don't work. I do not know if they work together.

Thanks

Yes, I am about 90% sure that the rear washer motor gets activated by the same driver chip as the wipers on a circuit board in the rear wiper motor itself.

Thanks. now I am 70% sure...can anyone confirm or denied.

Nothing to add here as I'm going on 4 years with it deleted :)

OK, I confirmed it for you, diagram ELE-392 in the Bentley manual. You should get one.

I cut 1/2 inch off the top of my wiper to get it to stop hitting the brake light and causing this skip. Also need the right springiness of wiper to follow the curve of the window.

On an old wiper arm you can usually get some more spring pressure by putting a stick between the spring and wiper arm (on the order of pencil thickness or a small metal rod like 3mm. Pull the spring out of the arm, put the rod across the arm instantly double the spring force without replacing the arm.

Yes they are one in the same. And I am 100% sure. The necessary chip on circuit board is known to burn out. I posted something a while ago about mine with pictures. Just get another whole assy and replace it. Very easy to do. Go on Ebay and find one.
