MY HORN ON MY 2000 S500 DOES NOT WORK IT ONLY CLICKS ON THE HORN RELAY, BOTH HORN AND RELAY REPLACED STILL NO SOUND
Possible broken wiring or bad connectors in the horn circuit.
Make sure your car is turned on. Without power some accessories like horn, garage door opener etc. do not work. If it still does not work refer to it owners manual & see if u Ned to replace a fuse? Good luck.
