How can I fix my 2009 Renault Megane Dynamique Convertible?

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?
