I will appreciate any help with this, I was driving and suddenly the horn starts to blast.
This happened without me pressing the horn pad switch in the steering wheel, I had to stop and remove the horn relay. The relay is good, I tried other relays, and the situation is the same.

I read that the airbag and the horn switch is a single piece, it seems that I can not replace only the contacts.

Believe it or not, the Durango has only 42,000 Orginal miles, wear and tear should not be a factor. However, please give me some ideas.

I had a similar issue with a 1999 plymouth breeze. Turned out to be weak "clock springs". There are small springs that keep the horn contacts from making contact. I ended up going to a junkyard, getting a second set of springs, weaving the springs together, and problem mostly solved. Occasionally I did have to punch the center of the steering wheel to stop the horn after the double spring upgrade.

A clock spring is not what keeps the horn button from making contact. A clock spring is a wound up conductor/ribbon cable in an enclosure in the steering column that transmits signals and/or power to steering wheel buttons -- like the horn, audio controls, cruise buttons, etc. Clock spring failure usually results in those buttons not working, so no horn, cruise.

The springs you installed are not clock springs --- but probably have some other name.

Problem Solved. The membrane switch (horn switch) was making contact. I removed the center pad, and I removed the airbag from the center pad. Then check continuity, the contact was closed. Then I proceed to remove the membrane switch from the center pad. I inspected it; there was no evidence of any damage such as corrosion, humidity, or cracks.

Once I removed the membrane switch, I started to flex it slightly, making sure I wouldn't crack or bend the material. While I was flexing it. I could hear small crackling noises being the two sides of the contacts separating; after the noise stop, I checked continuity, and the contact was open again. Proceeded to reinstall it, no more issues

It'll probably fail again. Those types of switched have internal separators and once they fail, they're done. You should probably look for a replacement.
