My 2005 Liberty CRD started refusing to accept new CDs in the changer a few days ago, and eventually just spit out all the CDs that were in it. Can't get any to go back in. Doesn't seem to have anything to do with which CDs (i.e, they aren't dirty or scratched). I'm suffering with just the radio so I'd like to fix this. Any ideas? Is it maybe a dirt/dust issue or more serious failure of the unit? I'd rather not replace it with aftermarket as I like the stock plus don't have a lot of extra spending money now.
