The sticking passenger door switch is the problem. When it's stuck, it overrides the function of the drivers side, including the fuel door release. To remove switch, I use a putty knife about 2" wide, wedge it between the switch and the oppening in the door, and slightly pry with putty knife while gently lifting/jiggling with a finger under the switch. Alternately, you can pop off the door panel and simply push the switch out.
