How do I Replace a Turn Signal Switch on a 1997 Buick Century?

Turn signals are necessary for safe and legal operation of the 1997 Buick Century. The turn signal switch controls the signals. The turn signal lever is part of the switch and protrudes out from the steering column, allowing you easy control of the on-off function of the turn signal system. In the event your 1997 Buick Century suffers a turn signal failure, and you have basic automotive-repair skills, you can replace the turn signal switch in less than 20 minutes.

Things You'll Need

• Trim tool
• Phillips screwdriver

Instructions

1. Pry off the Century's upper clamshell with the trim tool to expose the turn signal switch. The upper clamshell is the semicircular trim covering the top of the Century's steering column.

2. Unplug the turn-signal wiring harness from the body of the turn signal switch by hand. Remove the screw that holds the switch to the column with a Phillips screwdriver.

3. Lift the old switch out of the Century's steering column and set it aside. Insert the new turn-signal switch by hand.

4. Install the retaining screw in the new switch, using your Phillips screwdriver. Plug the wiring harness into the new switch manually.

5. Reinstall the clamshell by hand.

Tips & Warnings

• If you paid a core charge when purchasing your new turn signal switch, return the old one for a refund of that charge.

• You can pick up a trim tool at your local auto parts store, if you don't have one.
