The drivers side power windows stopped working in my DB9. This is the second time this problem has happened and both times I now realise it has been due to the battery being allowed to run flat. The first time followed a period of 3 weeks where I didn’t drive the Aston and this latest time being when I forgot to disconnect my dashcams.

Both times I had not connected my Aston battery keeper to the mains whilst the Aston was in the garage. What I have also learnt is that whilst previously I believed my battery could support the dashcams for up to 4 days continuous running this is now only about two days. Perhaps my battery condition is gradually falling off. If I am driving the Aston every day then there is no problem and the dashcams can be left on overnight or a couple of days.
When I got into the car and pushed the start button other than some clicking noises nothing happened. I then put the battery on charge and left it for a few hours. On starting the Aston I found that the drivers side window was not operating it would not go up or down and did not move the approx. 5mm when opening and closing the door. I could however operate the passenger window up/down from the driver’s door controls and adjust the mirrors on both sides of the car.
The first time it happened I feared that the window actuator had gone down but thought I would first check the fuse (F83) in the cabin fuse box just in case it had blown. You can learn how to access the cabin fuse box in this article. After I had removed the fuse (F83) and found it to be OK, when I put it back the door mirror motors started moving and when I then tried the window it was now working correctly.
If you have a similar problem to this try removing the fuse and reinserting it and things might go back to normal.
Here is a short video of the procedure that may be more explanatory.
