How do you replace the turn signal switch located on a 1993 Buick Century?

Disconnect battery ground and yellow air bag disconnect harness if so equipped. Unscrew the horn trim from behind. Remove center nut on steering wheel. Use a steering wheel puller to pull steering wheel. Remove some of the dash plastic to get at lower part of column. Unbolt the 2 bolts on the column support. Unscrew the 2 or 3 torx fasteners that hold the switch in place. Unplug the switch from the harness midway on the column. Reverse procedure.
