Missing Lights in door

Hi.
Some lights in my passanger front door is black.

Missing lights in door handle, the light strip, and red indicator lamp.

So far, i have checked fuses (engine room- and trunk). - all fuses seams to be ok.
Bulbs- checked ok (the red indicator - the others not checked)
Ordered a new control box (as in picture). Still not lights.

So - what to do next. Is there a fuse I might have missed?!
Some others tips to what to do for a not very tech guy?!

Is it break in cable or need to take of the door inside-, I`d think its out of my competance area (I probable break something).
Not a big deal, but very irritating



Same sw nr and edition. Same same, so this is not the problem...



Lights in knob for opening window, and dor lock is ok

You need to check the continuity of the lights with a multimeter. The red light facing the ground is easy, but the other two will require the door card to be removed. To my brief internet search, the LED lights fail often.

It wouldn't surprise me if the control module needs to be coded to activate the ambient light package either.
