It's not the selector you need to replace. It's ';PRNDL'; indicator. Yes, you need to remove the upper and lower column shrouds. To do this, turn the ignition to the RUN position. Using a straight pick, insert into the hole underneath the lock cylinder and depress the lock detent, while pulling the lock cylinder outward at the same time. Place the selector in the lowest selection (1). Remove the steering column tilt lever by grabbing it with a pair of vise grips and twisting it counterclockwise. Now remove the two steering column shroud halves by removing the three screws that secure the two together from underneath. Now remove the one screw that secures the ';PRNDL'; cable to the gear selector lever. You may need to lower the entire steering column assembly to gain the clearance needed to remove the cluster assembly. Hope this helps.
