I have been pondering the nuisance of my gas door for a while and need some suggestions.

When I unlock the vehicle the gas door is unlocked also as designed. I don't like it. Then it is too far open to stay fastened closed so when I drive down the road it flops. When I lock the vehicle the door is too far open for the lock to engage. In other words, for the gas door to stay shut one must hold the door closed and lock the car. Of course when I unlock the car the gas door opens up again which means I can't drive the car with a closed gas door.

I can't find any adjustment. Poor design. The gas door should stay locked until I want it unlocked. Not everytime I unlock the car.

Suggestions for a fix? I just want the door to stay shut while driving.
