Diagnostic Aids

WARNING: This page is about a different car, the 2010 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.

Poor AM and FM radio reception is dependent on multiple influences, some of which may not be vehicle related. Areas which have high RF traffic or block the signal path may cause a degradation in radio reception. Radio reception may also be influenced by items within the vehicle, but not part of the radio system. Such examples are aftermarket electrical accessories or other items which may generated noise in the vehicle electrical system.

AM reception is highly dependent on the powered antenna receiving battery voltage from the radio. The powered antenna has a built in antenna amplifier that boosts both AM and FM reception. When the powered antenna no longer receives power, the radio will still receive FM stations and loose all AM stations.
