Power Door Lock Switch
NOTE:
Use self-powered test light or ohmmeter to test power door lock switch. Some switches contain diodes. Reverse test leads during resistance checks before condemning switches.
Remove switch from mounting. Continuity should exist between terminals No. 3 and 7 for switch illumination. See Fig 1. With switch in LOCK position, continuity should exist between terminals No. 4 and 6. With switch in UNLOCK position, continuity should exist between terminals No. 1 and 4. If switch does not test as indicated, replace power door lock switch.
