The nuts on your prop pump under your hatch that is !
Went to change the oil yesterday and hit the hatch button to only hear a
motor running sound but no hatch lift.
Not a very good feeling in your gut ,had a limited amount of time to do what I wanted to do .
So I found between the back rest and the top cushion in the center
4 bolts that hook to the top of the piston . It is very hard to get your
hand in there but once you find the bolts you can use a long extention
and 7/16 socket on it. Once bolts are off you can lift hatch.
I found the nuts were off the studs that go to the worm drive that
hooks the pump and piston together on the bottom.
Tighten them and save yourself this problem

Road runner

also add a 6'' round flush hatch under the cushion if you ever have a problem it's real easy to get to. unscrew and you can get your hands in.

Good Idea!!!
