[W126 Coupe] Horns not working

[kirk erichsen]

I don't think the bulb outage indicator is related, the indicator is notorious for false positives. Did you check the fuse for the horn? It's shared with instrument lights if I recall. When you push the horn did you blow the fuse? The horn contact plate could be your issue if so. The relay is in the engine compartment fuse box from memory, you can pull it, clean the contacts and a dab of di-electric grease, but that's rarely the source of the problem.

> My horns stopped working. At the same time, I have a warning light on my dash that an electrical device (light bulb,etc) is malfunctioning.  I checked my fuse and it appears to be in good shape.  I suspect that there is a horn relay somewhere in the circuit but I don't have a wiring diagram; can anyone tell me what and where I should be looking for?
