PERFORM THESE STEPS FIRST

1. Check for open in the Horn Fuse.

2. Check for power to the Horn Fuse by noting normal operation of the Courtesy Lamps.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
