My E320 has a few electrical faults, gremlins or whatever you want to call it.
The electric mirrors and the seat belt warning system doesn't work.
The left heated mirror is out of function. The right is okay, probably the left element that's busted.

Everything else (power mirrors, seats, moon roof etc) are in fully working order.

Could it be the switch for the mirrors that's faulty?
What about the seat belt warning system?

Thank you for any clues and hints.

Edit 18. April: I can also add that when I open the rear doors, the dome light doesn't light up. It's okay when I open the front doors. There's also a button in the dashboard for interior lights, but this is out of order. When I press it, the lights in the luggage compartment doesn't light up.

Do you have the original wiring harnesses?

If you think about the engine harness; it was replaced a few years ago at the cost of about $ 2650 (Things are expensive in Norway)
The electrical problems seem to be fixed.
New switches and a dodgy wire to one of the interior lamps seemed to be the reason for my troubles (=
