I have the dual climate control style HVAC in my '03 Silverado (the up and down levers, not the *****). First the right side bulb went out, but now the left has just gone out as well, making it very hard to see where the temp. is at exactly at night. Where can I get replacement bulbs for it (part #'s too if anyone has them), and is it easy to change these bulbs out in it?

 

Also interested in this. My AC and recirculate icons don't come on at night.

 

I took mine apart and wired up LED's to the board. There is a thread about it on here somewhere. The bulbs are soldered to the board, not a simple replace job.
