Electric window and wing mirror indicator

[Markpaw]

My passenger side window stops working intermittently and when it does I've also noticed that the indicator on the passenger side wing mirror also stops working.
I dont know if it's a coincidence but the only time I've noticed this has been when someone has been sat in the passenger seat. It happened tonight and as soon as they go for out it was all fine.
Its a 2017 a class.

Thanks in advance

Hello, try pushing and holding the window button down and keeping it held down for about 5-10 seconds after the window has opened and then closing the window and holding the button for 5-10 secs longer after it is fully closed. It may offer a glimmer of hope before a trip down to the garage.

Hmm, a four year old car?
Try opening and closing the door or flexing the rubber wiring conduit in the hinge area with the indicator working to see if its a wiring issue there.
A lot of these work of a door controller and must be a common fault location.
