Anyone else had intermittent problems with their horn?  Yesterday someone drifted into my lane and I found the horn was not working.  Confirmed it didn't work for the whole trip home...  This morning, it works.  Yesterday (when it wasn't working) it was raining and I'm not sure if somehow that had something to do with the issue.

 

Anyone else had this issue or any kind of horn problem?  I hate intermittent problems as I expect the dealer simply to say they can't find a problem...

I remember reading in another forum where someone else had this problem and the dealer traced it to a faulty PCM. This is what I would suspect if the problem is intermittent. (Esp if problem resets after a restart).

Other causes (more permanent in nature) would be a faulty horn itself or (more commonplace) corrosion at the horn connector.

(I had one horn on my old Sable that had to be disconnected once a year and cleaned. Used contact cleaner and grease at last time and thst seemed to fix for good.)

Thanks for that.  I have not been able to reproduce the problem.  I'm pretty sure, but not completely sure, I tested the horn when I got home the time I thought it wasn't working.  The car is so quiet though, and I don't know if the noise cancellation stuff might do anything, but I will say the horn is hard to hear when driving down the road!

The N.C. is not that good.  You should clearly hear it when driving.

My horn is quieter than before.  It is in the dealership right now.  They said the system was defaulting to the rear horn (not the 2 in front).  Now they say it is normal, but it wasn't like that when I got the car last year.  My son has the same car and his horn is really loud.  He had a "low voltage problem" he said.  Also, didn't the alarm chirp when you set it???  I thought it did (though not loudly), but now mine makes to sound whatsoever but the lights flash.  Anyone else have this problem??
