Hi guys,
after a heavy rain my stilo right front headlamp got wet. I dried it out and fixed the hole but my low beams are gone and i getting sometimes alternatr. fail loose connection message, after reading this forum I think it will be the bad earth in the lamp, my question is where is the earth in the lamps?

The right headlamp earth is in the multi earthing point under the right front wing in front of the windscreen washer resevoir. You will need to remove the wheel arch liner to access it.

The problem may not be due to the headlamp earth. As you have other warning messages, it may be water in the engine compartment fuse box, especially if you don't have the battery cover fitted. There's a guide to drying it here: https://www.fiatforum.com/stilo-guides/313986-how-clean-dry-out-fuse-box-near-battery.html
.

Thank you. I'll do it at the weekend and give a feedback.

I cleand evrything and the problem sloved. Thank you very much.
