my drivers side horn did not work, so i adjusted it and still nothing. so i took my passenger side horn off and put it on the driver side. there was no hook ups for it on the passenger side. It works great. i am trying to fix my driver side horn inside, my friend came by to see my car and i wanted to show him my horn. well when i press the horn button the tachometer jumped!!! what is going on with this? thats not supposed to happen is it? by the way does anyone want to trade a horn button with no cracks for a horn?
