Passenger window and mirror problems

[xpack]

Hi folks hope you can help. 2010 ML350 w164. My passenger door window won't go up or down and the mirror won't fold in or out. I can make them work using my icarsoft tablet. I have attached screenshot of the fault showing up on tablet. Been suggested it's the switch unit, what you think? Also Window doesn't work from switch on passenger door

Broken or intermittent contact in the wires in the rubber boot between the door and the body. Not uncommon for wires to break there due to the constant bending with the opening/closing of the doors. Far more common on the drivers side though.
