Ok, so here's the thing. I replaced the handle last year and everything has been working great. For some reason, when I went to open the tailgate to grab something from the back it wouldn't open. I don't even hear that three click sound sequence that indidcates it's trying to open. There's nothing, as though it's still locked. So I removed the door panel from the inside to try and open it manually but even that didn't work. I can see insideand that the hanlde is moving but the door won't open. Any ideas how to get it open so I can figure out what to do next?
