tail gate locking faults on 2000 Volvo V70

My tail gate door does lock and it can open but when lock is not too secure as in you can hear it moving back and fort as on the dashboard the trunk light always remains on and the trunk light if not switch off manually it does not goes off as it suppose to when the tail gate door closes.

Here's some Volvo shops near you if you need one:
Good Luck!
