    I've had my Tacoma (2007, 4 cyl) for about 4 months and the horn fuse has blown twice.
    Anyone have any ideas on what the issue is here??
    Thanks!

    Are the horns still in stock location? If not they may not be grounded properly.

    Bare wire touching metal between the horn and the fuse.

    Solution: Quit blowing your own horn.

    Hmm, that wasn't helpful now was it?:D

    Dark Knight - As far as I know the horns are in the stock location - I haven't move them. I will look into this to double check prior owner didn't do any mod.

    LGE - good thought. I'll look for that

    Moose - ha

    If you have a multimeter, or a test light, you can unplug the horn and test the circuit back to the horn relay. With a multimeter, you can check the resistance between the horn wire and ground. It should be very high, if not an open. With a test light, connect the lead to the battery and the test light to the horn wire. It should not light up. If it does, or if you get low readings on the multimeter, then you definately have a short between the horn and the horn relay.
