Rear wiper started playing up on Thursday night continuous wiping when in the 'on' position. Switched the wiper stalk to off and back and seemed fine until Friday morning when it wouldn't work at all. Checked all the fuses and none blown (no idea which supposed to be the right fuse as the chart indicates a location with no fuse or terminals for the wipers fuse). Rear washer still works and putting the car in reverse when the front wipers are on the rear wiper still doesn't work.

Assumed motor must be gone so fitted a new today and still nothing. All I can think of now is the relay, so anyone know where it is and which one?

Iirc there isn't a relay.

Not really what I wanted to hear. Hopefully your memory is playing tricks on you.

Given the known frailty of mkII wiper motors, I would be looking to change the motor.

Changed the motor earlier today for a new one with no joy. I've also just been out to the garage and the original motor I was able to get moving using an old battery on pins 1 and 4. 

Does everything else at the back work? Amy sign of water under boot floor? Could be a leaking washer pipe.

It was all totally dry, no signs of leakage. Washer jet still works when the boot is closed but not when it's open which confirms boot closure is being read correctly.  it's only the wiper arm itself which isn't working by either the stalk or by putting the car in reverse with the front wipers going. All fuses checked by the drivers door and under the bonnet. This is my reasoning on it being a faulty relay.

What year is the car?

Could the wiper arm itself be seized? Can you move it freely with motor not there?

2012 model Wiper arm not seized as just moved from old motor to new one. It's on a splined shaft so it would be the motor itself that would seize up preventing any rotation.

will look at a current flow diagram.

Cheers Wino.

Fuse 18?

I have checked them twice but will try a new fuse just in case.

Removing and reinserting the same fuse has got it working again. Not sure how this can be as the fuse was pulled and checked twice previously prior to changing the motor. Inserted a bit of contact grease and a new fuse in case of any corrosion but the old fuse looked clean anyway. Slightly stumped onto whats happened and quite annoyed I've splashed the cash on a new wiper motor that i probably didn't need.
