Hello!

We have an 04 Frontier and a while back the horn acted as if it was going out. When my husband used the key fob to lock the doors, the horn made this wimpy almost muffled sound (wimpier than the typical horn sound :)). He said he just gave the horn a couple hits and it was back to normal. Then, out of nowhere it started doing it again, but this time the couple hits didn't help. And, he said the horn makes that same sound whether he uses the key fob or presses on the steering wheel.

While at a friends house, his friend took the horn off of his wife's car (Not a Nissan, if that matters) and put it on the truck. The horn seemed to work for a few minutes, then back to the wimpy/muffled honk. So, he just put his horn back on.

Then, when he got home he went to lock the doors, and the horn sounded normal.

He said he has checked the fuse and it's fine.

Any ideas of what it could be and/or what to check? I've read on other forums that there may be mud or water in the horn, but he said it's clear of any of that.

Any help would be much appreciated!
Thanks in advance!

Laurel,

Just to clarify, your friend's non-Nissan horn sounded fine and then started with the same whimpy sound? If that's the case I would certainly suspect the relay - although anything on Idleone's list could be the cause.

Correct, the non-Nissan horn worked in the Frontier for a short time, then went to the wimpy sound.

I'll tell him to check out the relay as well.

Thank you!

I have the same problem with my horn. turns out mine was full of dirt. The location of these things are perfect for mud splashing up into them. Blast it with air or water or like i did take it apart and clean it. Re install facing horzontal not down like factory and not up as a rain catcher but horozontal. Mine has worked well ever since... I'm just a dumb carpenter waiting for that first beer.

The horn starting working perfect on it's own the other night....maybe there's a horn fairy out there :) I'll also give my husband thy info as well in case it starts up again.
Thank you so much!!

I kind of thought swapping it out with the other horn would have ruled that out... guess it's possible that horn had a problem too, but I would think it's not very likely.
