Front Limit Switch
Remove front and center pillar trim and disconnect seat belt motor connector and limit switch connector. Move buckle to front by winding motor with emergency handle (in Owner's folder in glovebox). See Fig 1 .
Continuity should exist when buckle is fully forward, and not exist when buckle is moved away from switch. See Fig 2 . If readings are not okay, check wiring to switch. If wiring is okay, replace switch.
