after my son has taken his dash out to have the clutch pedal box repaired the now has no wiper i have checked all the plugs on left side seen to be all connected same on the right ,have power at the fuse both sides but nothing at the motor or from the switch ,have i missed a plug some where

did you also make sure all earths were refitted?

yep all earths hooked up about to drop the dash back out and recheck every thing

ok dash back in all wires hooked up i did notice theres a black box under the dash about 20cm long i thing is the bem has the same colour wires coming out as the wipers is it possible that is where the wiper relay is
