Howdy all. I'm having some issues with the rear hatch on my 2000 Explorer Sport. The remote unlock won't open it, nor will the key open it. This once was an intermittent problem but now seems permanent. The only way to get the door unlocked is to crawl into the back and flick the lock switch above the wheel well a few times. The problem seems to be an electrical one of some sort, but I have no idea where to start here. Anyone seen this problem before? Any suggestions? My wife has eliminated the idea of me taking it to the dealer for a potentially costly repair given what the value of the Explorer is these days, but it's a royal pain not having it work.
