Hi there, I am Cam. Can I ask your first name please? With your issue, so if I understand this correctly, your gas door and trunk are intermittent or inoperative with electric releases?
Customer: replied 1 year ago.
Inoperative was working now can't open with fob or by pushing button on main panel inside. The other key fob not working either
Expert:  Gm Tech (Cam) replied 1 year ago.
Ok, there is a fuse that feeds those 2 items. the Body 15 amp fuse in the rear fuse block. Check that fuse. Second, take your release button and find the relay in the rear fuse block for the trunk and the fuel door. Use the button and see if you can feel the relay click when you use the button. Let me know what you feel when doing this.
