Tech Notes for B125A 2015 Chevrolet Silverado
B125A:02 Antenna Signal Circuit Short to Ground
B125A:04 Antenna Signal Circuit Open
Poor AM and FM radio reception may be due to multiple influences, some of which may not be vehicle related. Areas that 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 generate noise in the vehicle's electrical system. Aftermarket window tinting, especially when there is metallic in the film, may reduce radio reception.
AM reception is highly dependent on the antenna amplifier receiving battery voltage from the radio and being properly grounded. The antenna base has a built-in antenna amplifier that boosts both AM and FM reception. When the antenna amplifier does not receive power, AM stations may not be received, and FM reception will be limited. If the antenna base is not properly grounded, excessive interference in the signal may occur or reception may be limited.
