    Weird AM radio problem

    Everything about the sound system works fine except the AM radio. The reception quality varies commensurate with bumps in the road...clear signal then muted and then even cutting out on bigger bumps.

    I tried the search in the audio category and with a discussion on window condition. Mine's not tinted but did receive hail damage and I'll look for cracks. How hard is it to remove the headliner if I need to check the wiring?

    I have a similar problem. The first time it happened under warranty. The dealer finally replaced the radio. It would seem like the problem is in the antenna circuit since the FM doesn't have the same problem. You might pull the radio to make sure the antenna is connected correctly. I don't listen to AM that much, but my latest issues might have started with a windshield replacement. That might just be a coincidence though. If you found anything, please post so that I can diagnose mine

    AM radio should be using the chassis as the antenna. So there's probably a broken wire some where. I have no idea how the antennas for the AM is routed. But not on the windows.
