Did you ever solve this problem? I have just had my windscreen replaced and have exactly the same problem.
No i still havent solved the problem! i was hoping for an answer on here before paying some extortinate price for renault to fix!
If you find a fix then please let me know.
I would return to who ever replaced/repaired your screens as I'm sure any repair centre must be aware of the problems involved on cars fitted with auto wipers etc and I would presume this would be covered by your insurance company if it was repaired via them.
