Hi dear friends.

My Stilo suffers from multiple electrical fault. reverse sensor fault, rear fog fault and airbag faults from time to time

But more irretating is now that my left rear flashing/blinker/indicator light does not work at all. replacing the bulb did not help. Neither disconnecting the towbar wiring. when the bulb are disconnected I have 9v in the socket, but when reconnecting the bulb it drops to plain 0
Forcing 12v (directly from the battery) offcourse makes the bulb light up, and "funny" enough makes the indicator in the instrument go fast. It blinks in normal speed when removing the forced wire strange enough
Like the relay doesn´t know theres a bulb "missing". I therefore thought that I could cheat and draw a wire from the front flasher, but no. That only makes the rear buld glow very weak and again makes the indicator/relay go fast......
My question are : is the light and relays controlled by the body computer located
within the fusebox. If yes; if I buy a used fuse box/body computer does it need to be coded to my car with ex. fiatecuscan?
Sorry for my bad english. I hope this makes sense anyway
