Then I would recommend checking the wire that I suggested earlier in your post. I pulled the inside out of a saturn not too long ago and I seem to remember that wire. If your antenna is on the passenger rear of the car, it is definitely in the floorboard on that side. There is a long piece that connects to the antenna that ends in the floorboard with a connector. It connect to the piece that runs to the radio. It's free to check it. Just pull your trim on that side and life the carpet up and look for it. It looks like a black coax cable (like your cable or satellite comes in on). Check the connector and tighten it and see if it helps. If it does, take up the wire with something like duct tape to keep it from coming loose again.
