Inquiring minds want to know..
G,
Tell me a little more about your noise.. Is it ignition noise? .. buzzy, and changes pitch as the engine RPMs change? Alternator noise? A whiney noise, sort of like a hum, that changes with RPM? A constant static noise like an unsquelched CB?
Do you get the noise with the intercom off and on? One or the other?
With the CB (If you have one) off or on?
Aux input off or on?
CD player if you have one?
A combination?
What accessories have you added to the audio / intercom system? Passenger volume control? Kennedy switch sets or cellset? GPS? XM / Sirius?
Have you added anything recently?
Does this go away at a higher RPM? (Mine has an intermitent ignition buzz in the intercom, and it stops at about 3K-3.5K RPM. And only does it sometimes.. ) (I cleaned the contacts on my J&M passenger volume switch, and that seemed to help)
Does cold or hot influence it?
Is something near the spark plug wires? Or the coils?
<edit> Have you changed the spark plugs recently? If so, did it get resistor plugs put back in?
On an '02 (and my '03) I'm kind of inclined to think bad grounds. I should have cleaned mine the last time I had the tank out, but...
The "goes away when the brakes are applied" ... You said rear. Only the rear, or is it the same if you only use the front? I don't know what that might indicate, but if it's ground, maybe applying the brakes somehow improves the ground by using a different path?
