I recently bougth a 2000 E430 Sport

all the light at night time light up nice and bright.

the only light that is not bright is the air control unit A/C

is this normal, since this is my first Benz?

Thanks in advance,

Steve

Everything should illuminate pretty evenly.

If the entire climate control panel is dimmer than say, the gauge cluster, then it's probably fine.

If a portion of the panel looks a bit inconsistently lighted, then it probably is.

Amazing what difference a single burnt-out bulb can do...
