1. Locate the turn signal flasher. It is usually located under the dashboard, near the steering column.
2. Remove the old turn signal flasher. Twist the flasher counterclockwise to remove it from its socket.
3. Install the new turn signal flasher. Push the new flasher into the socket and turn it clockwise to lock it in place.
4. Test the turn signals. Turn on the hazard lights and make sure that all four turn signals are working.
If the turn signals are not working, you may need to check the turn signal fuse or the wiring to the turn signals.
