W639 Hazard light switch cluster not working

Hi,

First post so go easy on the newbie please! I've got an issue with the central switch cluster housing the hazard warning light, sliding door lock and rear interior light switches.

None of the switches work, so far I've checked fuse 9 and 39 which I believe may cause this issue and replaced the whole switch unit but no luck. There is power to the unit as the switch lights on the door lock and interior light switches come on.

Any ideas or clues?
