Cadillac 20965947 Ignition Switch

Disconnect the cable from the negative terminal of the battery. Remove the knee bolster trim panel, the knee bolster, and the upper and lower steering column covers, then lower the steering column to its lowest position. Remove the locking pin and disconnect the electrical connector from the ignition switch by depressing the red locking pin. Take out the ignition switch mounting fasteners and the ignition switch from the steering column, ensuring that the new switch snaps into place during installation, which follows the reverse of removal. Turn the ignition key to the RUN position and use a suitable tool to depress the Ignition Lock Cylinder release button located at the top, then remove the Ignition Lock Cylinder. For installation, insert the Ignition Lock Cylinder into the housing and push it in until it clicks. If replacing, ensure it is properly coded to match the original by a dealer service department. Verify that the ignition switch operates correctly in the OFF, ACC, RUN, and START positions, with installation following the reverse of removal. Removal of the lock cylinder illumination ring is not necessary for lock cylinder replacement; however, disconnect the electrical connector from the illumination ring, disengage the lock tabs, and remove the illumination ring, ensuring that it snaps into place during installation.
