Power Door Lock Control Switch
NOTE:
Some door lock/unlock switches contain diodes, always reverse test leads and retest, before condemning any switch.
Remove suspect door lock control switch. Measure resistance between door lock control switch terminals. With switch in neutral position, continuity should exist between terminals No. 4 and 6. With switch pressed to LOCK position, continuity should exist between terminals No. 1 and 4 and between terminals No. 4 and 6. With switch pressed to UNLOCK position, continuity should exist between terminals No. 2 and 4 and between terminals No. 4 and 6. If continuity does not exist as specified, replace switch.
