2007 Dodge Caravan - Radio

Car radio FM works fine. But when using the pa certain rogrammed stations for AM nothing comes in. When using the seek feature it just goes thru all the frequencies and never finds a station. No static at all either when tuning into a known AM station. Almost like the antenna is disconnected. But no work was done to the radio area. Any Ideas?

Yeah, your radio is broken. specifically the AM band.
