How did you try to open the frunk? On my 2009 BS, the only way to open the frunk is to use the key fob. The in-car switch does not work. Don't ask me why. These are the instructions from the 2009 owners manual. Maybe give that a try... (while connected to the lead in the fuse panel).I have searched and not found anything similar, forgive me if I missed something.
My car is completely dead. I have used the jump attachments in the fuse panel when my battery died a couple years ago and that is not working this time.
When I first noticed the issue, I had got in the car and turned the key and nothing happened. I was a little distracted so I hadn't noticed that nothing electronic lit up, but then my key would not come out of the ignition. I hooked up the jump leads and whichever solenoid holds the key in the ignition released and I was able to remove the key, but nothing else lit up. I was not able to even unlatch the frunk to test any battery connections.
If anyone has any ideas, I would be grateful.
Thank You.
Best of luck,
Eric
