My 2006 Pontiac GTO gas ⛽ door stopped working last week. I changed the push button on the dash and it still won’t open. When I need gas ⛽ l have to gently pry open the door to get to the gas cap. When I press the button the first couple of times I hear 👂 the noise from the door and after a few more try’s no more noise and the gas door remains closed. What’s next?
