This is my first post, so please be gentle :-)

I have a 1995 N-reg 440 that my wife "reversed into a post" while I was away on holiday; there was actually quite a bit of damage beyond the bumper. She then arranged to get it fixed for a princely sum (more than it is worth :-o) and in the process, we have lost the ability to squirt water on the rear window. My memory tells me that the water came down from a jet in the top of the rear window / hatch, but there is no obvious sign of this having changed. Also, Googling a number of similar models leaves me none the wiser either. I'm 90% sure there wasn't a pipe leading up the wiper itself.

All the front-end components look, and appear to operate fine, i.e. rear wiper operates; pushing the little grey button at the end of the stalk triggers the secondary pump to operate on the side of the washer bottle; the small hose leads from this pump away under the offside engine components, but to where... ?

When it was fixed, I have deduced from the childish scribblings on the 'quote / receipt' that the inner panels of the boot had to be removed (no great surprise there), so I assume the small hose is currently emptying itself somewhere in the boot area, though there is no obvious evidence of this (nor under the car after grey button use).

Any help much appreciated.

Sounds like it has either come loose or the hose has been trapped or the nozzle is blocked, I'm trying to remember where the nozzle is, it squirted up from a nozzle alongside the wiper from reccollection.
the manual says you have to remove the tailgate wiper motor and bracket to access the nozzle, then its a push fit in a rubber grommet. looks like you are going to have to get behind those panels

Grendel, thanks very much for this guidance.

I found the wee hole at the base of the wiper and got at the hose that plugs into it by taking off the boot trim panel. The hose looked ok and water came out of it when triggered, hence I stuck a big pin in the hole and some white stuff came out (looked a bit like limescale, though we have soft water here). It then started to work. A bit more wiggling of the pin in the hole and it worked better than ever, so I deduce it was something that had been getting worse over time. FYI The hose appears to come through a grommeted hole next to the top R hinge as you look at the open boot lid / hatch.

Thanks again.
