How to replace antenna on 1994 Geo Prism?

Answer 1

Just did it... You have to buy an exact OEM replacement. Unscrew the antenna unit by removing the two screws. Pull out the remaining metal antenna and the wire. A plastic tube that houses the antenna will need to be removed. I was unable to remove the antenna cable as it is clipped behind the dash. I cut the wire leaving about 6 inches remaining above the roof of the car. Remove the inside trim along the top of the driverside door, all the way to the fron window. Additionally, remove the small trim piece along the edge of the door beside the drivers side dash. With the new antenna unit, begin to thread the antenna cable through the existing roof opening along-side the original cable that remains. As you thread the cable through the body, take notice of a hole in the body on the inside of the car above the drivers side door. You should see the new cable pass by the hole. Pull the cable through the hole.(I had to enlarge the hole to accomodate the plug that attaches to the radio. I used a dremel tool with a grinding bit to slightly enlarge the hole.) Once you get the antenna cable through the hole, pass the metal antenna and cable through the hole in the roof until you can mount the antenna housing to the roof using the two screws. Run the cable under the door trim and down under the dash. Make sure the new cable does not interfere with your steering wheel or and thnig else. I hope this helps you. I would have loved to see this before taking on this project. I just replaced the antenna on my 1994 Geo Prism and found that only one piece of trim needed to be removed. It is the piece with the fuse box door on the inside drivers side. Once you have it removed you have access to a plug and cable that runs from the antenna to the radio. Unplug the antenna remove the screws on the outside, pull the old antenna and cable out,put the new antenna and cable in, plug it into the cable running to the radio, replace the screws and trim, job done! I followed above answer with one modificarion. Only had to remove fusebox molding. Unscrew antenna from roof.cut antenna wire and leave as much as possible. Pulled out clear plastic piece. Taped end of new antenna wire to end I cut off old antenna wire. Pulled new wire thru and connected to wire that goes to redio. No grinding.

Answer

Unplug antenna lead from radio and tie a string to the end of it and tape it so it is secure. Remove the screws from the antenna outside the car. Gently pull the antenna and lead out of the car with the string trailing along. When lead is out of hole cut loose the old lead and tie on the lead to the new antenna making sure to tape tie so it cannot snag in small passageway. Pull string back from under dash until new lead is in hand. Finishing pulling lead until antenna is seated in proper position. Rescrew antenna and then replug lead into radio.

I just did this today. It took about 2hours. Take your front tire off and loosen about 5-9 bolts that hold the innter fender panel on. Then you can pull back and disconnect 2-3 bolts that hold the antenna in. My problem now is that I can't get the new rod to retrieve back into the antenna. Hope this helps. Mike
