Found the horn bolted to the radiator sup****t on the driver's side. Had to remove air intake and left front fender liner as well as most of front bumper clips to get access. Replaced in thirty minutes after I got to it. -- Message posted using http://www.talkaboutautos.com/group/alt.autos.nissan.altima/ More information at http://www.talkaboutautos.com/faq.html
