Well, having problems with a non functioning rear wash wipe on the touring.

There's nothing wrong with the wiper motor, especially after I did a strip and rebuild on it (Will be doing a guide on how to do this as I'd bet there's a few touring drivers with sluggish / stuck rear wipers!) but when you press the button for the wash, the pump doesn't do anything, in fact there's no response from the system entirely as the wiper doesn't go.

Switch works (continuity tested), I've changed the relay block in the back and checked all the fuses in the box, none blown... but there's no power getting to the pump, any thoughts?

I'm going to try a new pump today, but I'm not sure if it'll fix the issue.

Pull out the switch, and link black/purple (6) to brown (2), then try the washers.

Will try tomorrow Brian, new pump didn't work either.
Must be a fault in the circuit. What does linking those pins do anyway? bypass an earth?
