Visual Inspection
- Visually inspect system components. Check for:
- Blown Door Lock fuse (30 amp).
- Damage to wiring harness.
- Corroded connectors.
- Binding lock mechanisms.
- Shake the wiring harness between the power door lock motor and the power door lock relay. Look for obvious signs of shorts, opens or damage.
- If the fault is not visually evident, verify condition and repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
