I have a 2002 and this morning I wanted to switch from my cassette player to my CD player. It was dark and when I went to punch the button I couldn't find it. It was dark and never noticed before, but I had to turn the dome light on. Anyway, are those buttons supposed to be lighted and I never noticed? if so how or where would I have those lights fixed. I know my temp control panel all the lights are out. Is it an easy repair or do I need to send it off to someone? I recently had my compas and temp light fixed
