Rear Wash facility had been getting poor recently Hardly squirted enough washer fluid to wet the window and took ages before any came out - Front wasn't anything to write home about either - more dribble than dousing but bearable
I know I thought run the reservoir down and do the old Viakal trick.
The following is a bit of a digress but maybe usefull for someone
- The pipes and jets tend to scale up over time especially if neat water is used in the past instead of 10% screen wash
- run the tank down to the bottom
- Nick wifes
or mums 
bottle of viakal- Squirt half a bottle in the reservoir and then activate the jets to get it to the nozzles (Front and rear)
- Wash the excess of the paintwork with a hose
- Go have a cup of tea (or other suitable non alcholic beverage) and return the stolen goods before they are spotted missing
- Repeat occasional squirts and wash downs to keep the stuff that is still active in the washer bottle going down the tubes
- when empty hose fill to rinse it out of the washer bottle
- Refill with clean water and 10% screen wash
- Have fun readjusting the jets cos now the front screen jets go straight over the roof when stationary at traffic lights
Satisfy yourself with a job well done
Well not in my case cos whilst the fronts were now perfect
The back one was p*** poor to non existant
So bit more investigation required
Remove battery to check flow at the pump/solenoid - bets on me having to reset the service light?
Pulled the pipe of the pump - blimmey loads of flow (Basically while she pushed the stalk I was watching) Now a bit damp - I thought it's a long run from front to rear whats the odds on a kinked tube restricting flow
Off with the trim on the inside of the hatch nice rubber joining piece removed and she gets to push the stalk again - oooh I thought I didn't get wet - just dribbles out of the tube after ages waiting to get any through. When it stopped flowing it dissapeared back down the tube like a rat up a drainpipe...... Now I am suspicious - it shouldn't go back down the tube
I worked out where it went - in through the bulkhead under the carpet on the passenger side then along the car on the passenger side on the inside of the sill - So have a quick look under the carpet
bit wet down here - well actually very wet - time for the bounty!!!!!!So off with the door seal and interior trim carpet prised up and check the pipe for splits - none found
But when the squirter was activated more water/screenwash appeared
So it's a three door so of with the trim panel on the passenger side by the rear seat - Lift up seat cushion - deep joy its screenwash city under the seat too - more bounty
Get off pannel what did I find?
You may have already voted but we've narrowed it down a bit since then so what was it?
1. Split pipe
2. Holed pipe
3. Split joint
You all decided?
There is a join right by the seat back rest locating pin insde the panel and it a flexible bit of rubber bout 3 inches long to join the plastic tube and the plastic tubes are 3.5 inches apart
I managed to work a little bit of slack at the bulkhead end all the way back along the sill to recover 3/4 of an inch and the put the thing back together with some mini cable ties as a belt and braces just in case
Spent next 30 mins trying to bounty up any other water puddles - may have to revert to seats and carpets out for a proper job at the weekend but it'll do for now.
Like I said it might help someone
