I've trying to get my horns to work, Everything is hooked up, fuses good, its reading .2 coming from the plugs at the horns. Does this sound right. Removed horn and tried to ground the horn and try to tap it on my battery hot post. Still didn't work. Would the horn not be bad. Where could I get another replacement horn that would work without any problems.

 

Horns are twelve volts. Sounds like it's bad to me. I have heard of this being one of the standard problems with 4th Gens.
Auto. Parts and dealers have horns.
There are some after market horns also that might last longer.
