Well I haven't tested anything else yet because there's a new clue. It only loses voltage after in rains and I found out the rear carpets are getting wet.



I did the pour test with the sunroof open and found the front drivers side wasn't draining. Took the A-pillar cover off and the tube wasn't really in the hole. Sadly the carpets are still getting wet and the battery is still draining if it rains. Next thing I want to do is get inside the car and have a kid drench it with a hose.
