Reception Noise

It is very important to have a good understanding of the customer's complaint because many reception conditions are the result of the characteristics of radio waves themselves. The table shows conditions which can not be repaired. Compare to a similar vehicle to confirm that the condition is the same. If it is, explain to the customer that the condition is normal.

Check the following when working with poor reception/noise conditions.

^ If tint is applied to the rear glass, make sure that it is a nonmetallic tint (metallic tints are reflective) and that the glass antenna imprints were not cut during tint application.

^ Make sure that the rear window butyl sealer does not touch the glass antenna imprint as the sealer is slightly conductive and can negatively affect reception performance.

^ Check the grounding of the antenna, antenna cable and radio when ignition, turn signal, or alternator whine noise is heard during AM reception.

^ Make sure that all noise filters and choke coils are properly installed and any aftermarket products and wiring are not effecting the audio system.

^ Check the condition on a station with no signal (off station).
