The power liftgate stopped working. Does not open with button on the liftgate (glass doesn't open either), the button on the dash or the key fob. I pulled the fuse out, and put it back in, and the liftgate worked briefly (doesn't appear to be a fuse issue). Any solution? Also, is there a way to manually open the liftgate from the inside? I didn't see any of that info in the owners manual.
