Stuck--Attempted to add some air horns...

[nakedwaterskier]

HELP please. I have a Taco 3rd Gen TRD Offroad. I had some old but working air horns in my garage. I disconnected 1 of the 2 stock and added a compressor with 2 horns. No giant compressor just the regular old type. Worked great till the 4th time I used them and held down for 5 seconds. I figured I blew the fuse but I swapped a couple fuses and still nothing. Then I tried swapping relays too; still dead. ANY SUGGESTIONS? Neither the air horn or the one stock horn is working now.

Start looking for in-line fuses and or fuseable link wiring. Also, by pass the horn switch. The compressor may have drawn enough amps to damage it.

Weird...only a 10 amp fuse that did not blow...horns still work when i jump direct to battery

Fuses and relay fine...to get to horn switch probably a pain with steering wheel airbag...

I think I will just rig a new horn circuit/relay and switch. All other functions on steering wheel seem to work.
