SWITCH-HORN

DESCRIPTION

A center-blow, normally open, resistive membrane-type horn switch is secured in a plastic tray that is inserted in a pocket sewn on the front of the driver side airbag retainer strap. The horn switch is concealed behind the driver side airbag module trim cover.

If the horn switch is damaged or inoperative, or if the driver side airbag is deployed, the horn switch and tray must be replaced as a unit.
