A168 A-Class Electrical Question

[50volt]

Hi All. Maybe someone out there can help?
Got a 2000 A-class. It has four electric windows. The other month, the lights in the two front electric window switches in the centre console went dim for a while, then went off completely. I have noticed the lights in the back door mounted switches are also out. However, the lights in the rear window switches in the centre console are working. Is this a fault with the module that contains all the switches? I can't see it can be a fuse. I've taken it all apart and can get to the bulbs, but they don't look replaceable. Any help would be appreciated.

Thanks.
