Horn issues

[Timbers]

I have a 2015 GMC 2500 HD

I have horn issues. It was working then it started to weaken...then it stopped working. Now it started to work again but very weak. The dealership said it would cost me an undisclosed amount because they are not sure what the problem is. I've read several complaints about this issue on the forum's and find it hard to believe that they have not heard of this issue.....that is what they told me. Any advice would be great.

Thanks

I just saw this I had the same issue on my 2016 2500hd gas job ,and other ones now . I had to replace the horns n harness dealer wanted 500 plus with labor .... if you dont have a warranty just change it out for some train horns ... hopefully your dealer is better

So about a month ago my horn went high pitch (low tone was inop).  It was so silly that my wife and son made fun of it.  I ordered the horn assembly from the dealership.  It was like $36.  Well today was the day I changed it out.  First make sure that you use up all the windshield washer fluid.

 

1. Drivers side front wheel off.

2. Wheel well liner out.

3. Drivers side battery out

4. Battery tray out

5. Remove lower fender well/windshield washer bracket

6. Remove windshield washer tank (pull the pump out, disconnect low washer sensor).

7. Horn is now accessible - disconnect the harness and single bolt and pull out through the front valiance

 

Sorry no pictures, it was cold and I forgot to document it.
