Switch, Horn: Description

WARNING: This page is about a different variant/trim than selected.

The horn switch for this vehicle consists of four individual sets of normally open contacts wired in parallel so that all four sets of contacts operate as one switch. The horn switch contacts are secured to, but insulated from a stamped metal floating horn switch plate that also serves as the mounting plate for the Driver AirBag (DAB). The horn switch plate is over-molded with integral plastic insulators for the horn contacts and routing clips for the contact wiring.

The horn switch plate is secured to but isolated from the DAB housing with four sleeved screws and insulating washers. Each sleeved screw passes through a small coiled spring retained by an interference fit within an isolator on the switch plate. A dedicated take out and connector of the steering wheel wire harness connects the horn switch plate to the vehicle electrical system through a connector on the upper edge of the switch plate. A mounting spring on each outboard side of the horn switch plate is secured within the hub of the steering wheel under a hook formation in the steering wheel hub armature adjacent to each horizontal steering wheel spoke.

The components that make up the horn switch plate cannot be adjusted or repaired. If damaged or ineffective, the entire DAB and horn switch plate must be replaced as a unit.
