thanks Ffloydey,been to see local garage who services for me and he,said pop in and he,ll hook up to it and tell me the fault.rear wiper not working and wet under passenger seet .i been trying to get it going so i think the problem is to do with that as some members say the pipe comes apart and wets the control box under seat so it seems a coincidence that it was ok untill i was messing with that.and its wet down there.see what happens when ive been down to see him.maybe he can fix it while i,m off work this week.
