2004 C2 Cab Horn question


Recommended Posts

Hello all,

My 2004 C2 Cab seems to have the driver side horn out (higher frequency horn). Before I take off the front bumper and start to replace the horn, I need to know if both horns use the same relay and fuse. In other words if the right side horn still works, is it safe to assume that the problem with the left side horn is that it has died and is not potentially caused by a relay or fuse? I also would like to buy the horn and replace it in one session so I don't have to remove the bumper twice or worse, I cant drive my car because the bumper is off and I am waiting for a part.

Any help or insight on this repair from others who have done the replacement would be greatly appreciated. Seems like I have seen a thread on this or some other board dealing with this very same thing but all of my searches turned up nothing.

1 relay (position 10) and 1 fuse (25A).

I would put in an aftermarket horn like the Griots.

Fairly simple to wire in and use the existing relay and fuse.

Thanks Loren. As always I can count on you for a prompt and to the point response. I appreciate it.

So I discovered a strange thing with the gremlins in my horn system. Originally I had thought that the high frequency horn had failed since the low frequency horn only sounds when I hit the horn on the steering wheel. So I decided to see if my high frequency horn would work when I intentionally set the alarm off. Yep, the high frequency horn honks just fine when I set the alarm off.

Now if both horns are controlled by the same relay, fuse and wiring harness, and the low frequency horn sounds when I honk from the steering wheel, what the hey could possibly be stopping the high frequency horn from sounding when I honk the steering wheel horn? Clearly the high frequency horn works when the alarm is tripped so what would make it not work when I honk from the steering wheel?

Anyone have any ideas? :huh: :huh:

Thanks in advance,

Mike

The alarm horn is separate from the vehicle horns.

The alarm horn is next to the battery and the vehicle horns are behind the front bumper.

Chances are one of the vehicle horns is bad. My would replace both or put in an air horn like I did. :D

LOL! I think I will pass on the air horn Loren. I guess I just assumed (you know what they say about assume) that the alarm horn was the high frequency horn from the steering wheel.

Thanks for setting me straight. On second thought, maybe the air horn is not a bad idea :P

Loren, Can you install the Griot's Air Horn in the same location even with a 3rd radiator?

Yes, it is above the third radiator in my car.

Loren,

Do you need to install relay for using the airhorn? Or, you use the original wiring (with the origianl 25A fuse)?

Thanks,

Sinclair

The 25A fuse seemed plenty enough. There were two horns - now you have one (albeit louder).

So I used the original wiring and skipped the extra relay.

Is this horn still available? Or are there alternatives? One of my horns is out and if I'm going to go to the trouble of pulling the bumper, I'd

like something better, if possible.

Thanks
