I just got a 2000 Discovery II with the Harmon audio package. Everything seems to work just great except AM reception is practically nonexistant. I get better reception in my 1980 Chevrolet van without an antenna.

I know the antennas are in the rear windows, but is there a system/switch/fuse/whatever that controls the AM antenna that could go out? I listen to AM most of the time and it would be great to get it working.

Thanks,
Ken
