How to Replace the Turn Signal Switch in a 1998 Monte Carlo

The turn signal switch in a 1998 Monte Carlo translates your commands from the turn signal stalk to the turn signal bulbs. The stalk mounts to the switch body inside the steering column. The switch wiring harness provides electrical power to the switch, and allows the switch to pass that current to the turn signal circuit. As you can imagine, without a fully functioning switch, the entire turn signal system is useless. Anyone with a little auto-repair experience and less than 30 minutes of free time can replace the turn signal switch on a 1998 Monte Carlo.

Things You'll Need

• Trim tool
• Phillips screwdriver

Instructions

1. Remove the clamshell from the top of the steering column by prying the right side of the column with the trim tool and then lifting the clamshell off manually. The clamshell is the half-moon-shaped trim cover on the top of the Monte Carlo's steering column, just in front of the steering wheel.

2. Unplug the wiring harness from the turn signal switch by hand. Remove the retaining screw from the switch with a Phillips screwdriver.

3. Lift the old switch out of the steering column by hand and insert the new switch in its place.

4. Thread the retaining screw in by hand and then tighten it with the Phillips screwdriver. Plug the wiring harness into the new switch by hand.

5. Reinstall the Monte Carlo's clamshell in reverse of how you removed it.
