We replaced the radio in my 2002 Gls V6 Sonata. Now the interior lights don't work. Also the right hand side taillight does not work nor does the marker light. Part way through we had to disconnect the radio. While it was disconnected, everything was ok.
The right hand marker lights and and taillights have at intermittent times stayed on when no lights were turned on. The radio that was in the car did not work either. We just got this car.
Also wondering, there is a white connector that hangs down from behind the knee panel on the driver's side. What is that for? I watched a video and they briefly said that isn't supposed to hang there but didn't say what it was for. Not a good video.
