Horn System Test (Part 2 Of 2):

Refer to Horn System Test table. If the horn does not sound, check horn fuse located in the Power Distribution Center (PDC). If the fuse is blown, replace with the correct fuse. If the horn fails to sound and the new fuse blows when depressing the horn switch, a short circuit in the horn or the horn wiring between the fuse terminal and the horn is responsible, or a defective horn switch allowed the horn to burn out.

If the fuse is OK, test horn relay (Refer to ELECTRICAL/HORN/HORN RELAY - DIAGNOSIS AND TESTING).

If the relay is OK, test horn. Refer to Horn System Test table.

CAUTION: Continuous sounding of horn may cause horn to fail.

Should the horn sound continuously:
- Unplug the horn relay from Power Distribution Center.
- Refer to Horn Relay Test.
