Do i need to extract the entire plastic frame housing this control and the radio and the OBC just to remove the climate control block so i can change the light bulb? I gave up when it wouldn't come out far enough to work on. I hoped i could open it and swap the bulb without having to remove the cables or hoses or wires or whatever connects to the back i was afraid i'd never remember what went where but while i got it out part of the way from its place it just wouldn't slip out the rest of the way no matter how much i stretched the plastic opening and pulled. I didn't want to break anything. Do i need to take some molding and panels off ?
