  Q: How do you remove and install the ignition switch on Mercury Grand Marquis?

  A: To remove the ignition switch the following steps was followed; one was to disconnect the cable from the negative terminal of the battery. After that, it is necessary to take off the steering column on both sides and the knee bolster. For models from 1996 and earlier you have to remove the retaining nuts and then lower the column to get to the switch screws. In those models that were manufactured from 1997-2004, the switch lies to the right of the steering column and to get at it, one has to pull out the metal reinforcement panel behind the knee bolster. Disconnect the cruiser multi-function, insert the ignition key to the RUN position, loosen the two switch installing screws; the ignition switch pulls out from the actuator pin. In installation, make sure that the actuator pin slot of the new ignition switch is in the RUN position and simply place the new switch over the actuator pin and tight the retain screws in place while switching the position of the new switch up and down to match the position of the screw holes. I then replaced the electrical connector to the switch, put the upper steering column cover into position and tighten the nuts to hold the steering column into position. Last, reattach the lower column covers along with the succeeding lowering of the insulator panel, and reconnection to the negative terminal of the battery.
