Identifying Concerns

IMPORTANT: When testing for audio reception or noise, the vehicle should be outside away from metal buildings and utility lines, with the hood and rear compartment closed.

1. To help isolate the source of the noise, identify the ignition switch position where the noise is most noticeable:
^ Turn the ignition switch to the ACCY position and listen for the noise.
^ Turn the ignition switch to the RUN position with the engine off.
^ Turn the ignition switch to the RUN position with the engine running.
2. Turn the ignition switch to the position that the noise was most noticeable.
3. Remove the vehicle fuses and circuit breakers one at a time until the noise has been eliminated.
4. Identify which systems or components are powered by the fuse.
5. Reinstall all fuses and circuit breakers.
6. Disconnect the components powered through the fuse one at a time until the noise has been eliminated.
