Re: Where is the horn??
Behind the passanger fender. You might be able to access it by pulling the plastic fender liner, but I'm not sure. I know you can get at it quite easily with the fender off. You also may be able to get access to it by taking the front bumper off and looking behind the fender in front of the wheel.
