- Window not auto-down completely:
Is the window slow? Try lubing the slides to speed it up (down?). It is also possible that the auto circuit is showing its age and tripping out early.

- Window open/close for door opening:
I haven't had a coupe since '92, can't remember that far back. I don't recall this feature on the C124.

- Inside light: Not on unlock, wish it would, and wish the headlamp switch lit up with the key, ...

- Sunroof opening automatically:
Does it in slide also, close it most of the way with the key, when you come back and unlock/open windows, the sunroof will slide back open.

- Passenger door not operating alarm & auto-windows:
In the doorjamb just aft of the lock assembly, there is a large black cap. Pull this out, the connector for the door lock switch is in this cap, you can unplug and test the switch for continuity there.
