The horn circuit consists of a horn switch, clockspring, horn relay, horns and Integrated Power Module (IPM). The horn switch is a membrane switch located in the airbag trim cover. The horns are located forward of the left front wheel behind the bumper fascia.

The horn relay plugs into the Integrated Power Module (IPM) which is located in the engine compartment. For circuit information and component locations, 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.

The horns will not function if the switch is "CLOSED" for more than 30 seconds. Once the switch is "OPEN", a 20-30 second delay will occur before the horns are functional again.
