2003 ALTIMA Back left door will not open

[la1]

the left back door will not open. Neither inside or outside handle will work or the clicker. The solenoid for the door just makes a buzzing sound when using the clicker. The inside lock knob will not go to the fully unlock position. the door handles there is no resistance. I don't think i can get the inside door cover off. Looking at the other door that can open the cover has a flashing that goes out on either side of the door like a thin piece of plastic and is covered by the sill on the frame when the door is closed, so its wedged between the door and sill/frame.
