Popping And Or Static Noise On AM Radio Station Only - keywords

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may complain when listening to a very strong AM station (50kW), if you come within 1 to 2 miles of that AM stations transmitting tower, you will begin to hear popping and static noise. As you get closer to the tower, the signal will become very distorted. The customer may also complain of intermittent response to radio controls when near the tower.

They also may complain when listening to a moderate to strong AM station, the customer may complain that another AM station was "bleeding" over to the station they were listening too.

Note: For this issue the popping/static noise condition is only present when listening to AM stations.

The concern is due to an incorrect resistor being installed internal to the radio. Only repair is to replace radio assembly after verifying the customer complaint.

Please follow this diagnostic or repair 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.
