OK doing my head in - lovely polished black car this morning - my stupid fat arms - one quick ' squirt ' and now all over my bonnet / bumper screenwash... so need to wash / re wax... anyway i can just disconnect it ? is there a fuse ? i dont want it working anymore !!!

 

Yes fuse in fusebox under bonnet take it out.

Cant remember which one but its in your manual

 

Can't miss it, it the first fuse towards the front of the car. IIFC it is labeled as well.

Just a side note, there are 2x fuse box, it is in the smaller one nearer to the battery.

 

ah so its on the small fuse box by the battery perfect !
