Service VME - Buzz Type Noise from CD Changer in Trunk - audio CB radio rear static U1S

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

On Park Avenues with factory installed trunk-mounted CD changers, when the engine is running, there is a buzzing noise heard between tracks of the CD. To correct this concern, engineering has suggested separating out of the right body harness and IP harness, twisted shielded harness from radio to changer. Circuit #s 1705, 368, 367, 372 should be moved 4 inches away from the main body harness. When the circuits are separated from the main harness under the seat, they should be taped to the floor to remain secure.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
