Huydai sonata interior lights do not work why?

Can you turn the interior light on manually? My 2009 Hyundai Sonata has two switches on the interior light fixture. One is labeled 'Door', and must be depressed for the light to work with the doors. The other switch is to turn the light on/off manually.

No promises but this is the only reference I could find for Hyundai where the fuse box was not behind a panel to the bottom side of steering wheel. It may inspire you to look elsewhere behind items. Good Luck.

"The interior fuse panel is located behind the coin holder pull out drawer, which is on the lower left side of the dashboard"

typically there is a switch on the light or a control on your dash dimmer control. If adjusting the switch with the door shut does not turn off the light within a couple minutes then the switch bad and would need to be replaced.

could be the light timer

Check the altinator for output volts and battery problems.

sound like a fuse problem. there is one set of fuses under the driver side dash area and another under the hood in a black box marked fuses.

The reflector/cover of the interior lights are press fitted only. you need to remove the same with some small tools like screw driver at right point where they provide a small opening.

Once you have removed the cover, you will gain access to the bulbs.

It is most likely the alternator.

Hi

Make sure all door switches are functioning properly. See that each switch pushes in and out, without sticking.

Here's the wiring diagram
