Technical Doblo Maxi (263) proble with fog lights switch

[sscekic]

Hi to all, I have Doblo Maxi 2010 2.0 JTD and my fog lights don't work. Since on same switch are buttons for for lights, rear window heater, headlights adjustment switch and hazard lilghts switch I checked fuses, relays, disasabled swith because only hazard lights are OK but nothing else. All LEDs are OK but there is no change when I press some of those control buttons (except hazard lights) - I got no info on dashboard.
So, any help would be usefull, specially if someone can send me wirings diagram for that part od electr. so that I can check and maybe find solution.
Thanks in advance.
