Help!

[09 CMax]

Hi All. Needing a bit of help with my Cmax.  Yesterday All of these faults appeared at once.

Handbrake light is on constantly.

Interior lights are on as if a door is open

Central locking will not work from inside car.  Fob unlocks all doors except the boot but Doesn't lock any. It's clicks and unlocks. 

Indicator lights on dash don't work (inc hazards)  or full beam light. But lights are working. 

Reversing sensors have stopped beeping. And lights on ignition off beeping has stopped. 

I had a dash cam fitted a week or so ago. Is it likely to be somthing related?

make sure all the plugs in the fuse box are all pushed in if that's where they wired the dashcam in
