Power & Ground
- Turn ignition on. Check for 12 volts at 6-pin connector between White/Red and Black wire terminals of driver's door switch (located inside driver's door). If 12 volts is present, go to next step. If 12 volts is not present, check power source, fuses, ground and related circuits.
- Check for continuity between Black wire at driver's door switch and ground. If there is no continuity, repair circuit. If there is continuity, check for 12 volts between Red wire at 12-pin connector of driver's door switch and ground.
- If 12 volts is present, power circuits are okay. If 12 volts is not present, check power source, fuses, ground and related circuits.
- Disconnect door switch connector at passenger doors. On passenger door switches (6-pin connector on 2-door), check for 12 volts between White/Red and Black wires. If 12 volts is present, power circuits are okay. If 12 volts is not present, check power source, fuses, ground and related circuits.
