Please forgive me but I am not sure of the current weather in Egypt

Has the weather been rather rainy of late?
Have you checked the fuse box?
Have you checked the door locking mechanism?
Also, have you removed the door card of the door in question and checked the wiring?
All I can think of is water ingress mate or a split/snapped wire.
Have you tried disconnecting the battery for a few hours and then reconnecting?
There is a thread regarding electrical gremlins lol have you read this?
