I have a 2014 Volvo XC60 3.0L, The trunk on the car opens up fully but once it reachs the top is goes back down a quarter of the way. It seems weak when it comes up so I'm guessing withing any tests that the motorized trunk is having an electrical issue or needs to be replaced. I saw online it said it the lock that grabs and locks it in place isn't in the correct pin placement it wont work. The pin is in the correct place so its not that.
