Horn System Test Table (Part 2 Of 2):

Refer to Horn System Test table. If the horn does not sound, check the horn fuse located in the Power Distribution Center. 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 is responsible.
1. If the fuse is OK, test horn relay. (Refer to HORN RELAY - DIAGNOSIS AND TESTING).
2 If the relay is OK, test horn. (Refer to HORN - DIAGNOSIS AND TESTING).

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

Should the horn sound continuously:
- Unplug the horn relay from Power Distribution Center.

Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
