The Jinx
Thinking about this the other night and I dont think my problem could stem from the relay. Basically the rear one wipes but doesnt wash. (sounds dodgy!)
Having swapped pumps over I know its not that. I also tried to see if there was a feed but got nothing even from the front one which I know works!
Would the relay cover the wash function or is it just the timer delay that its for? If it isnt the relay one would suspect the wires broken.
