The left and middle buttons on the climate control have burnt out. Anyone know size of bulb that goes there?

 

I think that mine are on the way out also, as they illuminate initially on starting and then die out. How do you get to these (2003 Titanium Edition) to replace them?
Thanks

 

In my A33 I30, the clock bulbs went out and i used a set of Radioshack, LED sized, 12v, flashlight bulbs. My experience with the A32 Climate control leads me to believe that the climate control bulbs can be replaced with the same bulbs i used from radio shack. But i haven't messed with the A33 climate control bulbs yet so i can't be 100% sure. The process for replacing the bulb is pretty easy but is very detailed. It requires removing the old bulb and routing the new bulbs leads the same way through very thin holes on the socket, i broke three leads and ended up with two useless bulbs before i got it right. AND you have to modify the new bulbs base because it comes heat shrinked and hot glued at the base. I wish i could get a write up on here but i still have plenty of posts to go before i can post a new thread. as soon as i can ill have a great write up with pictures for everyone to view. And im pretty sure the digital climate controls are the same in the max and I30 if im wrong my bad.
