does it work on AM. Ours will work for awhile on Fm and then quit,if youtake it out and wiggle the antenna wire it coms back on.Course oce you put it back in the dash it may work and it may not.  Not sure whether it's the antenna or the radio where the antenna goes in.. It wil work on Am ok.

   Only take about three mintues to get the radio out if you haven't done it yet.  Pop the dash part loose that goes around the radio and left hand side of dash reach in and squeeze the two clips that hold the radio. It will slide right out then you can take off the wires.
