I bought my bulbs from the dealer for $2.20 each, part # 5013815AA. I couldn't find them anywhere else.
Real easy to install. If I remember I had to take off the drivers side knee panel first than the center console. All screws were easy to find. The hardest part was getting the old bulbs out. It was literally a 15 minute job.
This happened to my 04 over the summer, but it was the instrument cluster that went out. Went to the dealer and bought 3 bulbs for around $4 I believe. Hardest part for me was getting the darn cables out of the back of it. The cc will take 2 seconds to swap out. One scrw be the most awkwardly placed hook ever, then pull the whole center piece out. Unscrew the cc backing and throw in the new bulbs. Put everything back and you'll be rocking again
