Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.
Dear customer, reading your question the most worrying is that there was a short cable discovered, the main fuse boxes of this Megane model are some under the dashboard and another under the engine compartment, when a short occurs most likely to be produce is that part of the wiring of the system is damaged or that the fuse itself is damaged without damaging the fuses, when this is the case, the complete wiring of the system where the damage occurred must be dismantled, and verify where the short occurred, as you are going to note that when a short occurs, somewhere in the wiring it melts a bit and even split, because of the overheating that occurs, this is what must be verified to correct this fault.
on, on the other hand, I am concerned that not only is the system affected, but that there are other systems that also stopped working, when this is the case, sometimes it is because in one of the places the connections melt and for this the fault or the short one covers several parts. This being so, we have to verify not only the wiring line but also the fuse box on the bottom where the wiring arrives, that has not melted or damaged this part, if so, the complete fuse box must be replaced.
Do you understand me, dear customer?
