My Mercedes Benz Atego hit a cow and the right corner head lamp and indicator plus grill got damaged. I replaced the parts but now the right indicators have stopped working. What could be wrong and what is the solution?
Is the fixture getting electricity? Have you tested it with a meter? If it is, your problem is possibly just a bad bulb.
If it isn't, then you have a wiring issue.. possibly a crimped or cut wiring harness, damaged during the collision. In that case, you're going to want to track it back to where it is severed, and repair it.
And now that I read @PoissonFish's comment, this is nearly identical to what they said.
