both headlights stop working on my 2012 Fiat 500
Yes the lights ab p ve the bumper, I already replace the headlight relay in the fuse box under the hoodThe American cars are different to over here, however, are you talking about the ones above the bumper ? If both are off I'd look at the relay, as over here there's separate fuses for left and right do all the other light work correctly? The ones in the bumper?
have you tested the relay is still working at that the bulbs arent blown?No sir
agree....back to basics tooSo, it's going to take some more in depth investigation.
With a helper turn on ignition but don't start, with a finger on the relay have someone turn on the lights, can you feel it click?
If it does click, remove it and check for a supply feed( power to lights, not feed to relay switching)
Use a meter, every thing off to check the continuity between the relay output and the headlight live(bulb)
If the relay doesn't click, and is known to be good, check for a switching signal feed, also check the earth for the relay.
If there's no signal then check the wiring back to the body computer?
Contact a auto electrician I'd say then, there's too many possibilitiesI changed the relay because someone mentioned that it could be the problem,didnt help. Dont have any meters to check anything and dont know how to use them anyway, will check the bulbs in the morning( Saturday)
Where would that fuse be located? under the hood or inside the carWhat controls/protects the wires that lead to the relay, a fuse? Which one? Have you checked thst fuse?
Fuse 12 and 13 in the passenger compartment (on European cars) but it would be unusual for both to go at once, one for each
