Quick question which I'm sure has an easy answer: My brother lives in DC while his car sits at my parents home in PA and I went to get his car inspected and needed to stop and get gas. I pulled up on the gas door release and the door wont open.......I even wedged something under the lever while trying to pry the door open. It seems like the black plunger wont retract to release the lid. Can I remove the trunk interior to get to the cable?
