    Q:
    How to Remove and Install the Ignition Switch on Buick Century? Posted by Feng C.
    A:
    The switch is fitted inside the channel of the brake pedal support and is not accessible at all without first lowering the steering column to which a certain support must be provided. It is operated by a rod and rack R8, where a gear is provided at the tip of the lock cylinder 'T' engaging the toothed upper portion of the rod. Optional equipment includes the Air Bag system and if so, then it must be deactivated before proceeding. The switch should be rotates with the OFF position unlocked at the two positions away from the top position of the switch and the rod should be in the lock position to the uppermost detent position. The switch assembly can be pulled out if the two switch screws are unscrewed. For installation, it should also be switched off and unlocked and the lock cylinder as well as the actuating rod should be in their positions. This activating rod should then be fitted into the switch before the switch is placed on the column and the mounting screws are tightened: care should be taken to use only the recommended screws to avoid compromising on the collapsibility of the column. Steering column also should be refitted at the end of assembly.
