What fuse is the horn fuse

if it is not on the steering wheel it may be on the multi switch, you might have to push it in from the side. just a shot in the dark here.

It's in betweenthe inner fender and the fender itself. You have to take the front of the inner fender loose to find it. Your fuse or horn relay may be bad. relays are interchangable.

Mine was in the wheel the contactee that turns back and forth had just enough wear that it didn't always have contact might check that real close

There's two of them located just above the parking light in front of each of the fender wells. You will be able to see them from the bottom looking up

recall but u have to pay for it if your suburban is over 70,000 miles it has to go to a dealer it about 450.00 it sucks my 2003 2500HD as problem.

The horn pad is made of vinyl which contracts through the four seasons causing this problem for some. Remove the horn pad with the battery disconnected first of all. Use a jumper wire to see if the horn works. If id does check the horn relay next. If ok hot wire the horn direct. One should be your problem or it is a broken wire instead

Usually, front grill or behind front quater pannels. get some earplugs and have someone hit the horn if one still works the other is a carbon copy.

did you check the horn relay it is a small box usually in or near the fuses or near the horn itself It may have been just the relay all along and not the horn

either it's in the fuse panel on the drivers side dash or in the power distribution box under the hood
