Clio 172 Auto Lights and Wipers

[markcp]

The auto lights and wipers on my 52 plate 172 have stopped working automatically. I can switch them on manually, but I'd like to get them working properly again.

Anyone have any suggestions what could have caused it?

Thanks,

I think mine stopped working after the screen was changed. Is there some way of testing the sensor, or doing anything to it to try and get it to work?
