Hey all in the hyundai elantra forum, i do not drive this car but my friend does and im trying to help her. Apparently, all of her interior lights just like the speedometer and heat/air are not on when she turns on the car. She went to get her aftermarker stereo fixed and this happened. I was thinking maybe a fuse or something? But i wasnt sure so i came to the people that know what they are talking about..any help is appreciated.

 

Welcome to the forum!

What year Elantra?

First thing to chack is the dimmer. Make sure it wasn't accidentily bumped all the way down. If the dimmer is all the way up, then check the fuse.
