lights on SLK 170

[KBJ]

Hi

Hopefully someone can help, not sure when it started but the interior lights do not come when doors are open, tried or the normal things but still no joy.

Also the seat belt warning light doesnt come one nor does the audible sound when seat belts arent engaged

Any thoughts

You tested at night?

Might be worth checking the pse pump to see if any damp has got in as I think this operates the light on unlock/lock.
Does it work from the switch?
Also silly q but is the switch in the correct position?

Hi
Yes it does work from the key fob, but not when i open either door
