How do you replace the antenna on a 1997 Geo Metro which broke in the automated car wash?

Looks like you'll have to remove the radio and just trace the lead back to the antenna. It either will have screws holding it in or a fitting around the base that has to be unscrewed. Check with Autozone or Advance for a replacement and see if your sales person will come out and look at it. They should be able to tell you how it comes out. I've always tied a strong piece of nylon string around the end of the old antenna lead before removing it. This way, you can tie it to the new lead and pull it back in the car. there are two screws on the outside of the car that screws the antenna to the car take them out and pull the wire out a little cut the wire then tape your new wire plug to the end of the old cut wire then carefully pull the wire through from the inside by pulling the old wire through and it will bring the new one to the radio
