Jumpy II - Crazy rear wiper

[Mateusz]

Hello
Have problem with rear wiper in my Citroen Jumpy II
While driving its starting randomly wipe and flush for few seconds.
Today catched it few times
What causing it? Anyone had simillar problem?

[wheeler]

what year is it?
My first thoughts if its a post 2007 model is the com2000 unit starting to play up.

[Mateusz]

Its 2010
Have you maybe electric schema output com2000?
I want to add simply switch into the cable to cut off rear wiper signal.

I had this problem on a Volvo some years ago! It turned out to be a faulty earth on a front light cluster. Might be worth seeing if anything else is malfunctioning at the same time!

Actually working on it.
Cut signal from wiper shifter is imposible because there is already integrated with computer and output signal is moddified. While cutting wiper cluster losing also light and indicators cluster.
Needed go other side and tracked way from rear DC wiper moto and DC flush. Sadly doing it without electric schemats because couldnt find anything to this model.

Ok, so in the UK your vehicle is called a Dispatch III.

There is no actual circuit diagram I can find specifically for the Rear wash and wipe, only the location of the harnesses and routing, but I have put up the diagram for the weash/wipe system generally, so hopefully this will give you some idea.
