Help! Ford explored passenger door won't open?

I own a 1999 ford explored and I've had problems with the drivers side door not opening before but now it opens on and off. However, the passenger side door doesn't open at all. I have tried unlocking the doors with the power locks the key fob pretty much everything possible, but it still won't help me open it at all. Does anyone have any answers on what I can do to fix this problem?
