That's not early, I was on my way to London this morning at 2.30am.
The cable might have disconnected and you should find it at the side of the dash or A post if you search there. If you need replacement door pillar switches I have two for sale ATM.

I couldn't resist........
Firstly, I've noted this in the past - a loose wire (orange) in the fuse box, hanging separate from main bundle. Not really enough reach to hang a short distance down the A pillar.
Looking at the wires from door to A pillar, I noted a black wire in the bundle but not hanging. Behind the main bundle a pair of wires coming from the engine bay, one of them black.

I need your advice again

It's none of those. It should be around the A post somewhere though
