Horn doesnt work now after swap

[Monty87ls]

I was messing around with the horns on my 4runner and rav4 and now neither work. I wanted to see how the 4runner horn would sound on the rav for a possible upgrade from one from a junkyard since the one that's on there isn't very loud.

Swapped it and didnt work, put them back on the cars they belonged and nothing. Checked the horn fuse on the 4funner and it was fine.

Any ideas? Thank you

Maybe the horn relays??

did you make sure to mount the horn to the body of the vehicle during the test? thats how the horn gets it ground connection.

I agree, double check the grounds are making good contact. If not, you might have damaged the horn in the swap but I kind of doubt it
