Power Mirror System
- If only one mirror is inoperative, diagnose and repair mirror. See POWER MIRROR MOTOR under COMPONENT TESTS. If both mirrors are inoperative, check fuse No. 18 (20-amp), located in Intelligent Power Module (IPM). If fuse is okay, go to next step. If fuse is blown, repair short to ground on circuit or component.
- Check voltage at mirror switch connector terminal No. 9 (Light Green/Red wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit in Light Green/Red wire.
- Disconnect mirror switch connector. Check continuity between harness connector terminal No. 11 (Black/Light Green wire) and ground. If resistance is more than 5 ohms, repair open circuit in Black/Light Green wire. If resistance is 5 ohms or less, check switch. See POWER MIRROR SWITCH under COMPONENT TESTS.
