Have searched and haven't found the answer.On my 2003 TJ the interior lights are not comming on part of the time. Other times they will. If you leave the lights on, no buzzer. several other weird things going on with lights and such. It is not the door switches. I have checked that out. I do have the situation that they key can come out of the ignition and the radio goes off. The light thing is new but could it be connected or is their something that controls all the light stuff.
