Condition/Concern
Some customers may comment that the AM radio reception is poor, normally manifested as increased static. Other radio reception (FM and XM) performs as
expected.
The antenna coaxial cables female connector is a segmented cylinder comprised of 6 fingers (or tines) that maintain electrical connection with the cylindrical
male connector by exerting an inward/clamping force against it. The fingers may be spreading and compromising the electrical interface between male and
female connector. This spreading results in an unacceptable rise of resistance in the AM/FM ground path, which comes across as static on the AM band. The
spreading of the finger may apply to one or all connection points of the AM/FM coaxial cable, from the antenna to the radio. Also, disconnecting/reconnecting the
coaxial cable may aggravate the condition.

Recommendation/Instructions
Note: There are multiple antenna connections in the body wiring harness. Only the AM/FM antenna coax connections need the sleeve. If the coax is equipped
with one way connectors, they are black in color. If the coax has a duplex (two way) connector that is dark (mustard) yellow in color and you are unsure which
one is the AM/FM connection, install a sleeve in both connectors in the dark (mustard) yellow duplex connector.
Install one coaxial cable sleeve, P/N 20972763, on the female side of the coax connector. Perform this operation on all AM/FM coaxial cable connection points
(from the antenna to the radio). One sleeve per connection point will be required. Use the following steps for installation of the sleeve.

1.

Position sleeve with the flared out side towards the female connector opening.

2.

Push in the sleeve as far as you can with your finger.

3.

The sleeve may not appear to be pushed all the way down; this is normal. Reconnect the coax cables.

Use the following graphic information for sleeve installation locations. Refer to SI for specific procedures to access these locations.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
