Bulb in holder is probably loose. Pull the climate control unit ( uses
the same keys as the stereo, about $12 at the stealership ), and on the
bottom you will see what looks like a button. A quarter turn
counter-clockwise, and pull it out. Push the bulb back in. If the bulb
does not appear loose, I would just replace it.
