My X got a driver's floor full of water, back in '21, so I dried it out for days, and set out to prevent future sunroof problems, thereafter.

I couldn't push/pull my .065 or .080 trimmer lines thru the front left-side drain, from either direction, even after removing the A-pillar cover & un-kinking the hose. I used my air compressor (set to perhaps 20psi (I forget), and eventually it cleared.

I ran water thru all drains, just to be sure, cleaned, lubricated, and tested the sunroof operation, pulled the fuse, and used clear paint protection film (PPF) to seal it shut, and voila, no more worries. I also made a roof rack (from black powder-coated wire mesh industrial shelving, with .75" square openings) specifically to protect the glass and seal from hail and fallen tree branches, since my X is subjected to both year-'round, being always parked outside.

I check the PPF everytime I walk past or use my X (though it's not been driven since fall, last year, due to a fuel delivery problem I haven't yet fixed), and the film is still good (I have the replacement film on hand for a quick fix). I'm glad my sunroof is non-pano; I wonder if I could have sealed one up?
