Window switch panel light on driver door not working

[Vvrjrlaw]

I own a 2006 cls55 amg. I have found that when driving at night with headlights on the window control panel on the driver door only half lights meaning I have lights for the two switches that control the front windows but the switches that control the two rear windows are dark. Obviously the bulb is bad. I checked all data but no info. I want to remove the switch panel and change out the bulb. Can anyone enlighten me? That's in advance for the assistance.

Do you have the switch which disables operation of the rear windows on?

No I'm referencing the assembly where all the switches are located on the driver door. Thanks
