Hi guys
Help needed please with horn on my clk55 w208 model not working tried to check fuses couldn't find any for horn so checked all it hem all good
Checked the horns and the airbag all looks good
Has anyone ever had this problem?
If so what the solution would be please?
Thanks in advance

The horns work off a relay, though I'm not sure where that relay is on the 208. Perhaps in the main electrical box under the hood?

Have you actually tested the horns themselves with a direct 12V to make sure they work? That's the place I'd first start.

Good luck.

Engine bay left, inside box F1: K40/2 covers f1 to f27, f37 to f45. relays A to J.

Fanfare relay is K40/2k6 on the circuit. Location is relay A on the board.

Sorted the problem was in the relays unit
Replaced that and horns works now
