LXi Dash Air Control Panel

[rrueckwald]

On the air control panel, or HVAC if you prefer, there are two buttons, a blue one for a/c and a green one for recirculating the air. Neither of mine light up when activated. The square colored cover pulls off from the front showing sockets for some kind of bulb.

Oddly, the backside shows a clue. Although the recirc button switch has four wires going to it (two connected to ground), the a/c only has two wires and no tabs for connecting two more wires. I am theorizing that the a/c button switch came with no bulb, and BB never put a bulb in the recirc button switch just to keep it the same.

Question: Does anyone have bulbs in these switches on their LXi?
