No Entrance Lights-No Door Open on Dash
 

I acquired a new-to-me 2003 X5 4.4 knowing it has some issues. I solved my alternator issue which in turn solved most of my electrical issues. I have been digging through wiring diagrams, but getting lost on where to look to solve this issue:

No entrance lights at all. No door open symbol on the dash. No puddle lights. Car acts like the doors are always closed.

Doors lock and unlock properly (except passenger front, need to replace actuator).

Fuses all good (F1 and F4)

I have already tried pressing the dome light button.

Lights that do work:
Front map lights
Rear map lights
Rear dome light (manual on, manual off). Does not illuminate upon entrance.
Glove box light
Luggage compartment lights (on tailgate)

It's possible that the faulty door actuator is causing this - I think the door actuators are controlled via a central system in the driver's door - and this includes the door open sensors. Check the PCB in the driver's door module for corrosion too...

Scan of faulty actuator? You should be able to unplug the bad actuator and clear errors to test. It's pretty common for a fault like a short to interfere with anything else on the buss.

Same here. No interior lights. A black interior makes it really dark at night. Pull fuse 14 and plug it back in. It's a module reset according to info I found this week. I have not tried it on mine. I'll do it tomorrow. Be aware, the alarm will go off!

Update-Still need Help
Replaced my faulty door lock (passenger). Still do not have any interior lights.
Testing with ISTA, I get this message: All my fuses are good. Can someone point me to more detail or a diagram of what I am looking for. I was not able to retrieve the diagram in ISTA for some reason. I know how to get behind the glove box to the general module, just don't know exactly what I am looking to test.

All the wiring diagrams and electrical information is in the Bentley manual.

Or in NewTIS or variants of original WDS.
