Fuse panels trunk was open and sometimes it won't open I will check the fuses first

It's electric, sometimes it opens all the way, sometimes it starts to open, stops and closes back up, sometimes it won't work at all, one time I went in a store and came out and the trunk was all the way open, another time all the windows were down and the trunk was open, and sometimes it won't open at all, is there a bad relay switch? I need to check the fuses?
