My 1994 Toyota Celica has a power antenna.
Begin by removing the wiring harness from your 1994 Mercury Grand Marquis power antenna. Remove the power antenna retaining nuts. The power antenna will come off.
power antenna, you can buy them from gm dealers for about $120
You would need to get a tool to remove the notched chrome piece that holds the antenna mast, or carefully use pliers to unscrew it out. After you remove that, the antenna itself is held by a 10mm bolt. to get to it you'll need to open up the trunk lining near the antenna location and remove that bolt. Then, pull the antenna far enough to disconnect the antenna wire and power. Assuming the antenna motor is still functional, you can then replace the antenna mast with a new one. Or, you can install an aftermarket rubber antenna.
the power antenna is located on right front. I jacked my car, and removed the right front wheel. Then there are some small screws which are keep the inner fender plastic. unscrew them. You can reach with your hand the power antenna. Unplug the power wire, and the antenna wire, and unscrew those small (8mm) screws which are holding the antenna in its bracket.
