How to Replace a 1999 Chevy Lumina Flasher Relay

Turn signals are lights located at or near the exterior corners of all cars, including the Chevrolet Lumina, that signal the drivers intention to turn. The driver activates either the left or right turn signals via a switch usually found on the steering column. The turn signal lights blink, thanks to a module in the turn signal electrical circuit called a flasher. Sometimes, this flasher malfunctions or wears out. As a result, the turn signals either wont flash or wont come on at all.

Instructions

Test the flasher

1

Have an observer stand near the back of the vehicle so they can see both turn signal lights.

2

Engage the parking brake if you havent done so already.

3

Start the car.

4

Apply the brakes. If the observer sees the brake lights working correctly, proceed. If one or both brake lights dont work, you must troubleshoot the brake-turn signal circuit or refer the problem to a certified automotive technician.

5

Activate the turn signal, first in one direction then the other. If the observer doesnt see the turn signal lights flash on either side, replace the flasher.

Replace the flasher

6

Turn off the car.

7

Find the flasher. The flasher is a cylindrical module approximately 1-inch diameter by 1-inch long, plugged into a connector. The flasher is found beneath the driver side dash, near where the steering column passes through the firewall.

8

Unplug the old flasher from its socket.

9

Install the new flasher.

10

Perform the Step 1 test to ensure the new flasher works properly.
