How to Replace Your Turn Signal Relay in a Hyundai Sonataby Contributor
As your Hyundai Sonata begins to age, it will start to have some auto part malfunctions. One such example is when your turn signal stops working. If you've checked the light bulb and there isn't a problem there. It may be the turn signal relay. Replacing this part is not something that requires an in-depth knowledge of auto mechanics, as most anyone can do it.
Get down underneath the steering wheel and locate the relay or fuse box panel. In most year models of the Hyundai Sonata, it's located toward the bottom of the steering column.
Use a screwdriver to open the panel box. The panel will either have screws to remove it and in which case, you'll need a Phillips head screwdriver. If the panel has no screws present, use a flathead screwdriver to pry open the panel.
Look on the diagram on the bottom side of the panel lid to locate the turn signal relay switch. If there isn't any label, it should be at the top right hand corner of the panel box. Without the label, you may need to perform some trial and error testing to find the appropriate turn signal relay or consult your owner's manual, if you have one.
Extract the broken turn signal relay from the box and replace it with a new one. Be careful when you remove the old one, as you can damage the other items in the box, if you aren't careful.
Verify that the new turn signal relay works and then put the relay panel back into its original position.
