Good evening. My mother had a little problem today with her Renault Megane from 2003 or 2004 I don’t know exactly now. And that the plug of the navigation system in the cigarette lighter broke apart and yes there was a short circuit with sparks. Now the cigarette lighter, blower control part and the spray nozzles (no water comes out) are out of function. Then of course I looked for all fuses unfortunately without result since all completely sin d. I used to disconnect the battery for a minute, but this didn’t help either. What can that be? Thank you for your help!
