Hi hope someone can help the wipers have failed on my wife's 2011 mk 3 scenic and I am trying to work out whats wrong...I have done all the obvious things plus all other suggested ideas on other threads....after taking apart both motors, the drivers side obviously had some water ingress so I have replaced it with a new one, still no joy. I was previously an auto electrician so I would like to understand how this system works, a wiring diagram would be great but I am unable to find one. I have checked both multiplugs (with power probe) I have a good feed on the red wire and a good earth on the black wire and the other 2 wires seem to be giving fast pulses which I dont understand. If anyone has anything they can add please help. Thank you

Thanks for all your advise....just wanted to follow up as I hate it when posts just stop unresolved...i fitted a second hand drivers side motor ( £140 worth a punt as new they are around £250 ) as it looked like the old one had been wet in there at some time surprise surprise still not working...but I could hear that the passenger motor was making a tap noise when i turned on the wipers..so I took the motor apart and noticed the motor controlled link arm was at its max travel causing it to tap against the wiper case...I then removed the two screws holding the motor magnets in place which allowed me to rotate the armature by hand which moved the link arm to its opposite stop position..resembled the motor and tried again and all good I guess the motor was in the wrong position which prevented it from turning...I still dont understand how they work electrical wise and to be honest i dont care as i am selling it and moving on to something German asap well as soon as I fix the central locking that Is...gotta love a Renault.
