The lightbulb from the AC button is burned. How can I change it?
Thank you!

Remove the knob and the bulb is right behind it.

i think i seen a post on this. the bulb is actually right behind the knob, just pop out the knob and the bulb should be right there.

Yeah. I just found it on Google on some other Mercedes forum.

"Remove the knob and the bulb is right behind it."

So I just pull on the knob. Thank you!

You may need to pry the knob off with a small screwdriver (put some cloth between the screwdriver and the console)
heres a link with a pic PeachPartsWiki: Heater Control Dashboard Light Replacement
the lamp is behind the small metal flap, and I hard a hard time removing the lamp and holding the flap open
so I ended up putting superglue on a toothpick and gluing it to the burned out lamp to pull it out.
be sure to remember the alignment on the dial & you may want to replace both lamps at the same time.
I used a Sylvania #2721 lamp
