2014 VW Jetta leaking

It’s been leaking from the light under my glovebox. It’s not my ac, only leaks when it rains/at the car wash. Just wondering if anyone knows what it could be because I’m not gonna spend extra money on the mechanic to do a leak check bc I know where it’s coming from. It would just be easier if I could say this is the issue fix it please lol🤦‍♀️
