It it's second gen, take the plastic cowl off the front outside the windshield. There's two fasteners that hold it in place. There's a connector on the end of the lead that fits into the connector for the window. Those are available at the scrap yards. No one knows how to take them off.
If it's third gen with a windshield antenna, it probably works the same way. That can't be fixed.
I checked the spare I have. It's about five or six inches long. On the outside of the car, with the hood open, follow the leads in the windshield as the come together at the middle bottom. You'll see the wires exit the glass and into a rubber cap. That cap is on the end of the antenna lead. Disconnect it and you should see the two fasteners that hold the antenna wire in place. Disconnect those and pull the wire out.
