I Have A 92 March 1.247cc . The Front And Rear Wipers Work Intermittent ,when I Wiggle The Wires Under The Steering Colum They Work And One Of The Relays Start Clicking Like Mad. I Was Wondering If Anyone Has A Wiring Diagram For The Wipers .........if Anyone Has One Could You E Mail It Too Me Cheers !!!!!!!!!!!
