I have a 2000 limited but my climate controls and radio lighting went out recently and i literally just replaced the bulbs today. Replacing the climate bulbs are a piece of cake, but from my understanding you cant really replace the radio ones. Since my radio lights went out i guess it make for a good reason to upgrade decks, but check your fuse's i think the one in particular is the ACC but im not positive.
Changing Bulbs in A/C unit!
I'm not sure if the link helps but i took the part numbers from the thread to toyota and they charged me like $30 for all four.
