What causes the electric antenna on a 1986 Olds 98 Regency Brogham with 65000 original miles to keep running when the car is off and no longer put the antenna up and down?

The antenna has a limit switch, and runs until it senses up or down usually there is a toothed nylon belt or cable, and a chrome mast. The unit is bad, unplug it. You cant just unplug a fuse because it also runs your lighter (the small bunch of wires) you may be able to pull it up by hand, or just replace the mast. Aftermarket is ok, but not an exact fit./ Consider a manual ant, or pay the dealer 100+$$, It is difficult to remove the top nut, let it soak with penetrating oil for a few adys, as the pot metal corrodes.

If the radio works fine with the antenna the way it is. Just remove the smaller wires that power the motor. This will prevent the motor from burning out. Good luck.
