Troubleshooting Hints

Try the following checks before doing the System Check.
1. Check Fuse 15 by observing the dome light,
2. Check Fuse 13 by observing the I/P compartment light.
3. Check that antenna connector and coaxial cable are properly connected.
4. Before troubleshooting a suspect speaker, check all connections to that speaker.
5. For proper noise diagnosis, take the car outside where the signals are strong. Close the hood and keep away from metal buildings or sources of radio interference.
6. Ignition noise on FM may indicate a defective ignition system.
7. Coated screws or bolts can cause a poor ground condition. Scrape ground screws clean of any paint or dirt.
