I had a weird thing happen the other day on my rear blower motor that might be related.aadadams wrote:In the DC Metro area the horn is VERY necessary!

I will replace the fuse today, but how do I check the relay? I measured the voltage by putting my fluke in the loop. When the horn is engaged the voltage increases, when disengaged the fluke drops to near zero. The relay clicks whether the horn blows or not when the horn is pressed.

Try replacing the fuse for the horn. In my situation, the rear blower stopped working. I thought "Great, there goes $200 on a new blower, it must be burnt out." But I followed through on the standard diagnostic procedures. What I found was an overheated fuse. Over time, fuses are exposed to a fair amount of external heat, and I guess it must have deformed the 15A fuse for the rear blower. I took it out, examined it (it was not blown) and replaced it with a new one, and voila! no more issues. The fuse was actually deformed from all the heat it had been exposed to.
Anyways, try that, and see what happens. I think there is a horn relay too, so check that as well.

Sounds like your on the right track. Continuity between horn switch and relay, and continuity between relay and horn. Should help you track down either a component failure (horn switch, relay, or horn) or a wiring problem (wire rubbed through, poor connection).aadadams wrote:I will replace the fuse today, but how do I check the relay?

Only way to fix some things is for it to completely go ka-put.aadadams wrote:I need a stable consistent horn for the texters and makeup artists on the roads, HELP!
you may be right, but........elpeede wrote:try a "new to you" horn from the breakers yard then
