- Locate your relay cluster. You can find this in your car's owner's manual.
- Locate the turn signal relay. This should also be in your owner's manual. If it's not, you can consult a service manual for your car.
- Once you can see your relays, remove the old turn signal flasher relay and replace it with the new one. Don't worry about installing it incorrectly, it will only go in one way, the right way.
That's it! You're back to blinking, and back to being a safe car on the road.
