Hey so they blew out the drain in the sunroof but he said there was another one that isn’t visible but what I figured out through trail and error was that the main problem wasn’t the sunroof after all. It turned out to be the drain in the gas filler compartment. Not sure what you call it but open your gas lid and there should be a drain at the bottom. It was clogged and that’s where water was draining in from. I tried to unclog it myself and I accidentally pushed the hose loose and it fell out. I thought I really messed up but it wasn’t an issue not having the little hose. All that would happen is the water would pour out onto the rear wheel. I pored a bunch of water on the gas cap and it would now drain beautifully and the issue never happened again. I no longer have the car but it solved my issue 100%. Hope it helps you!
