Question about Cars & Trucks
Easiest way is to swap in another relay. Many others on the car will be the same relay, same part number.
To test a relay, put voltage across the coil side of relay with jumper wires, and check that the power side of relay then shows continuity. If it does, relay is good.

Look at the flasher. you have 4 numbers. 30, 85, 86 , and 87. 30 is power at all times. 87 goes to the horn. 85 and 86 can be vise versa. One is power and one is ground when the steering wheel is pushed to sound the horn. But most likely the plastic button in the steering wheel is broken.

SOURCE: horn button sticks
Typical scenario of the horn pad needing to be replaced at the steering wheel, may have to search the wrecking yards for a replacement or take the pad off and try to discover what part of it is bad and try to repair what you have.
Some folks have added a button useing the same twop wires that control the horn pad, thus eliminating the need to find a replacement horn pad in the proper color etc. a hole drilled into the dash and the button installed makes it a lot easier and cheaper and yiou still have a horn.
Every once in a while the horn relay is the culprit but mostly it is the horn pad, be careful of the air bag deploying...disconnect the air bag fuse before doing any work on the electrical inside the car.

SOURCE: where is the horn relay
Hi, the horn relay is under the hood. On the Passenger side firewall there is a black cover with that should have "Fuses" written on it. Remove it and the horn relay will be one of the black square modules. It should tell you which one on the inside of the cover you removed.
