take your climate out (you don't have to take it out all the way, the bulb is on the top right, it's not an LED, it's a bulb)

here's a pic of the bulb, just takes a quarter turn to take it out, you may be lucky, and it mite just be loose... if so then you don't need a new bulb.
The bulb is about 3 bucks from a dealer, I have a few extra laying around if you want one, I'll just throw it in a $0.60 envelope, let me know.
