R350 Rear Hatch Problem

Hi All,
My '06 rear hatch is giving me trouble. !st time I try to open it, it goes up a few inches, sounds like the pump is out of fluid and drops.. Then if I hit the button again it goes up no problem. Is there fluid somewhere? Motor bad? Where even is the motor?

2nd problem.. Sometimes when I hit the tailgate red closer button , it goes down 1/2 way and goes back up. So I just close it by hand..Any Ideas?

I would bet one of the hydro pistons has went bad on you. They lay inside the upper section and point toward the front of the vehicle (internal, not external like most cars). To my knowledge they are electronic controlled and any fluid is sealed inside of them. possible a seal went bad and you will need to replace it.
