Horn: Description and Operation

WARNING: ON VEHICLES EQUIPPED WITH AIR-BAG, REFER TO RESTRAINT SYSTEMS FOR SAFETY PRECAUTIONS. DISCONNECT THE NEGATIVE CABLE FROM THE BATTERY BEFORE SERVICING COMPONENTS INVOLVING THE AIRBAG SYSTEM. ACCIDENTAL DEPLOYMENT OF AIRBAG AND PERSONAL INJURY CAN RESULT.

The horn circuit consists of a horn switch, clock spring, wiring, horn relay, and horns. The horn switch is a membrane switch located in the airbag trim cover. The horn is located below the right side headlamp.

The horn circuit feed is from the fuse to the horn relay in the Junction Block. When the horn contact is depressed, it completes the ground circuit. Then the horn relay coil closes a set of contacts which allows current to flow to the horn. The horn is grounded at the shock tower through the headlamp and dash harness. 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 pinout information and location views for the various wire harness connectors, splices and grounds.
