How to Replace a Turn Signal on a 1991 Chevy Lumina

Chevrolet introduced the mid-sized Lumina in the 1990 model year. The 1991 Lumina came fitted with a 140-horsepower, 3.1-liter V-6 engine. It had a 3.4-liter, 210-horsepower V-6 engine available in the sporty-looking Lumina Z34. The 1991 Lumina used a standard wedge-style body design and incorporated a plastic front grille. Two of the four turn signals on the Lumina lay behind this grille; the rear taillight assemblies house the other two turn signals. This makes removal of the grille required as part of replacing the front turn signals and removing the taillight assembly a part of replacing the rear turn signals.

Instructions

1

Open the Lumina's hood and remove the three screws on top of the front grille with a Phillips screwdriver. Remove the two screws at the bottom-center of the grille with a Phillips screwdriver. Pull the grille away from the front of the Lumina.

Remove the screws securing the turn signal assembly to the grille with a Phillips screwdriver and pull the assembly from the grille.
