Hi guys, i have an 03 discivery and i cant seem to figure out why my horn wont work. The horn use to work, one button on the wheel is broken so i swaped the horns to see if the horn itself is out. Neither of the horns worked so i think its something in the line. I checked the fuse in the engine bay and its ok, the relay clicks when i hit the button and im not sure if it is to click. Any advice
