Aston Martin Rapide S one rear door won't open via remote
Discussion
Hi guys,
I have recently bought a used Aston Martin Rapide S (2014) and it was all working fine until recently when the rear right passenger door stopped unlocking via remote, sometimes it randomly unlocks but most of the times it does not. Now it almost seems it never unlocks via remote. The door handle light also does not turn on. I can only unlock it from inside when pressing the unlock all door button.
Do you know what might be the problem? I tried to change the battery in the key fob but it did not help.
Any help would be appreciated!
Thanks.

We had this on a Rapide we worked on recently. There is a fusebox under the n/s rear seat, bit of a pig to get into... There are a couple of fuses (25A I think) that controls the left and right hand rear door, locking, window and seat latch (2 seperate fuses, one for left, one for right). We removed the fuse, it was OK, put it back in and everything worked again. Why... Because its an Aston...
Thank you so much, for me it looks strange it would be a loose connection, since from inside when pushing the unlock button it works 100% of time, it also seems to work via remote when I fully charge the battery of the car but just slight drop in the voltage of battery down to 12.6 makes it stop working via remote.
I will try that thing with the fuses I actually already wanted to try it yesterday but I struggle to find the cabin fuses - so you need to remove the left seat similarly as when accessing the battery on the other side? (Basically following this guide but on the opposite side - https://youtu.be/l-Z0lziJ0QQ)

If it works from the internal door lock switch then it's not the fuse...that is either blown or not - cant be intermittent (well it can but v unlikely)! Without a circuit diagram to hand to help, its possibly a device or connection upstream or downstream of the manual switch that is able to make the circuit that is playing up. Aston Installations could help im sure.

I tried this procedure with the fuse but it helped only for the first 2 times of unlocking with remote. After that the old behaviour when basically the door does only unlock via the interior button but only very rarely via remote was restored. Any other ideas? I am now thinling of trying to look into the door module but not sure how difficult is to get it out or where its located. We also did a quick video for aston martin rapid s how to access the cabin fuses since it was a struggle to even get into it.

Hope it helps someone.
No, there are 4 in total; Engine Bay, CEM, under rear seat and boot. Fuse 10 (25A) under rear seat fusebox supplies the Left Hand Rear Seat. From the look of the circuit diagram, there is one power feed into the door module and everything then connects into the door module. Historically Aston door modules have given issues, so I would suspect that.
