Hmmm, I hope that the method is the easier of the two I have in mind...

1. Remove ashtray peice. Now, with the ashtray removed, I believe the light should be exposed.... Is there enough space in there to swap it out?

2. Remove lower console wood (pull up plastic shift trim surrounding, from there, you can pull up the console wood from the front end.). Pull out "sunglass" bin below the ashtray (the small storage pocket). You should then see 2 screws at the bottom of the ash tray, on either side. Unscrew them, pulling out the entire ashtray mechanism, while releasing/sliding it from the storage pocket (or) cassette holders (whichever you have). And try and figure it out from there with the unit out.

Good luck!
