Default A3 8P - Backdoor not working

Hi guys!

I have a problem with my left rear door, and I'm kinda going crazy. I have tried to look around the forum but nothing really fits my problem.

Anyway, I have had no problems so far, but then last week when temperature dropped to -5, it started.

First, the dash showed that a door was open in the car, and the lights were on inside. Even though all doors were closed. This has now vanished.

Now my door lock is not working. When i press lock on my remote, the 3 other doors and the boot locks, but not this door. The lights do not blink either. The window button is not lighting up either, nor can I control the window from the drivers seat. I can not fell the actuator "moving" when i hold the handle and press lock. So its like there is no power to the door?

Then sometimes everything works, and than all of the sudden, nothing works. So it kinda goes back and forth.

Do you have any idea of what this could be?

I read somewhere that it could be the pin in the fuel opening that has died, but mine works perfectly.
The fact that it sometimes works and sometimes not works is strange?
If its the actuator that has died, than how come the windows do not work either?

On a different note, but maybe related. When i blink to the right, the light sometimes flashes quicker than normal (like when a bulb has died), this could be related?

Help me! I am going crazy!!!

Don't have an answer for you. It may help to add what model year your car is.
My central locking started having issues several years ago. The rear drivers side door was the first to not respond to a lock or unlock command. Front passenger door is now often not unlocking. My problem has only gotten worse to the point the key fob will no longer lock or unlock any door. And no, it is not the battery or the key fob itself as both fobs produce the same results with fresh batteries. Now using the key in the door and the controls in the drivers door only lock/unlock the drivers and rear passenger side doors consistently, sometimes controlling the front passenger door but the rear drivers side door now ignores any commands. Good luck and deal with it now if at all possible.
