HORN PROBLEM

[CADMAN]

Strange problem. When weather is hot, my horn stops working. As long as temps are below 80, horn works fine, when above 80, nothing. I've replaced relay, checked wiring and still nothing when it hits 80. I searched blogs to see if anyone else has had this problem. Any suggestions?

I would check to see if power is getting to the horn when it's not working. Could be the horn itself.

check that metal plate under the air bag see if there's any Corrosion then the relays then the horn itself.

When its 80+ out, take a DVOM (Digital Multi-Meter) and see if you have 12V going to the horn. If not, you just eliminated the horn. Just gotta start at one end, and work your way to the other.
