Turn ignition off. Disconnect Black 10-pin power mirror switch electrical harness connector and remove power mirror switch. Using an ohmmeter, check continuity between appropriate mirror switch terminals. See Fig 1. See appropriate POWER MIRROR SWITCH CONTINUITY TEST table. If continuity or resistance is not as specified, replace power mirror switch. If continuity or resistance is as specified, inspect switch circuit for defects or damage. See MEMORY SYSTEMS and POWER MIRRORS in SYSTEM WIRING DIAGRAMS article.
