Trouble Shooting

Verify customer complaint by operating power mirrors. Before performing individual component tests or system tests, check the following for possible cause of system malfunction and repair as necessary: blown fuses, loose or corroded connectors, damaged wiring, damaged motors, damaged mirror assemblies and faulty switches. If no visual damage is evident and vehicle does not have memory mirrors, repair by symptom. See SYMPTOM INDEX  table under SYSTEM TESTS. If cause of fault is not evident and vehicle has memory mirrors, perform DDM/DSM self-diagnostics. See SELF-DIAGNOSTIC SYSTEM  .
