You were correct. When I finally did manage to get the top to function (it started working on its own after a day of not touching it) I left the tonneau cover up and saw that the hydraulic system (the two pistons that I could see) was completely covered in fluid. It obviously is leaking. While it did respond this time, it definitely struggled like it never has before. I had to press the switch several times because it would completely stop trying. What do I do from here? I'm not exactly swimming in money, so I'd hope that it's an inexpensive fix... Any further advice is highly appreciated!
