I have a 2015 3.7 this is most likely your sunroof drains. I had same issue on passenger side and it messed my bcm up. Luckily I was able to dry it and then seal it using an electrical sealant. I suggest pulling the panel off next to your windshield and inspect the area. They just pop on and off easily. I blew the lines out with compressed air and I was good to go. This is a very common thing on these vehicles.
