This is phenomenon known as the Renault electrics nightmare syndrome, you're not alone with this problem, type Renault into the search bar, you will see what I mean. The electrics have a mind of their own, it's like having a poltergeist taking over the wiring loom. Solution: 1.Take it to a local garage, they will shut the doors and pretend they are closed. 2. Take it to a Renault dealer, how long will it take to fix and how deep are your pockets?
