I've only got the drivers one working right now so I need to do something.

I've read the posts that say they pop off but what bit? Is it just the bit that tilts that comes off or the whole unit, tilty bit and base?

How much pressure do you use and how have you cleaned them to get the buggers working again?

On the rear how do you get the plastic cover off the base of the wiper to get at the nozzle?

TIA

Buy a new pair - they're very cheap, and you'll see how they come out of the bonnet - anymore than 10 seconds and you're doing it wrong.. If you live in a hard water area they can be a bugger to clean properly so you might as well leave the old pair in the dishwasher basket for a week then use them as a spare pair.

Washer fluid failure at the rear might be a blocked nozzle - or it's quite common for the feed pipe to come off. It's under the rear trim - plenty of posts on here about it.

Attacked them with an old toothbrsh and some gunk degreaser mixed with vinegar. Did the trick on the fronts.

Got the rear off as mentioned above, it comes apart quite nicely to let you into the nozzles. It was blocked with some brown stuff. Looked more like dried vanish than screen wash residue. Anyway managed to blow that out and it works fine. Ta.
