A few years ago, you had an issue with a 996 - no interior lights, no locking and alarm. In addition to what you described, my key fob is not working and the frunk is not responding to the interior release. I have access to the frunk. Battery is new. Did you ever find a resolution? I've been trying to isolate this one for a while.
Happy July 4 and thanks for any solution or advice.
