Greetings Franpu, for the year of the vehicle it is possible that the "switchera" has wear in its contacts, I would like to remove the cylinder and observe how the contacts are, use contact cleaner and then a little oil. I am not sure if this model uses a relay to activate the board, check in the internal rifle (inside the vehicle) if anyone says "accessories", try to remove it and turn on to see if it is the indicated one (if you do not turn on). There are other vehicles that take the energy of the direct board of the switchera (obviously going through a fuse, tell us how it went. Greetings.
