2001 Bonneville AM radio reception poor, how to find antenna?

I have a 2001 Pontiac Bonneville. I listen to AM radio 90% of the time. I bought the car new, and for the first few years the AM reception was great. Now it's mediocre. I suspect a corroded AM antenna wire conenction somewhere but how do I find the AM antenna to check the whole length of it and all the connections?

It is most likely a bad connection where the antenna connects to the bodywork clean any rust from under the antenna if there is any. the antenna needs to connect to a good clean metal ground plane ie. the car bodywork.

You need to remove the radio.. The wire is plugged at the back usually a thick black wire. Also check at the antenna end.
