Dug a little last night, hooked it upto the OBD Eleven.
Washers are enabled, live data shows theyre not activating..I then ran a test on them and they work....to a fashion, one works fine but the other isnt spraying a mist, more of a trickle. Anyway its ruled out a fuse and the pump i think?
Going to check tonight and see if the nozzled blocked up, not sure why that would stop them working on stalk pull though?
