    Q:
    How do you remove the ignition switch? Posted by Customer
    A:
    Proceed with removing the ignition switch by disconnecting the two wiring leads, starting with the one farthest from the steering wheel. Remove the stud and screw securing the switch to the column, and lift off the switch, making sure to pull it up from the column due to the protruding ignition actuator rod. Before installing the new switch, use a flat-head screwdriver to move the slider inside the switch to the 'Accessory' position on the extreme right, then slide it two detents to the left to the 'off/unlock' position. This position is necessary for installation. Place the switch on the column, guiding the actuator rod into the slider recess. Install the stud and screw, tightening them to specifications. Finally, connect the two wiring leads to the switch and reverse the procedure.
