Both power windows and mirrors adjust not working | A3 8p1 2004

[samorayunited]

I have an Audi a3 8p1 2004 (three door model)
I left the car parked for 3 weeks and when I came back the battery was empty.
I took it out, charged it overnight, then put it back in.
Everything is fine except for the windows. Both windows don't go down from driver side switches and also from passenger side.
Also, they don't work with keyfob (long press).
I tried to also control the angles of the side mirrors (not to be confused with folding mirrors which I don't have anyway) from the driver side and that doesn't work either.
The lock and unlock buttons from driver side work fine.
I opened the fuse box inside the cabin, checked for blown fuses, but no blown fuses. I even replaced some fuses there just to be sure.

If anyone faced a similar issue, please help. thanks in advance!

Check the battery is at 12.5v or above, door locks are a common issue aswell as door hinge rubber wiring that breaks.

The door locks work fine.
I read online about the door hinge rubber wiring issue but the windows are not working on both the driver and passenger sides from both switches. I think it's unlikely that the wiring on both door hinges broke at the same time.

Check it, don't assume.

That way it's discounted.
