Pull it off carefully. Straight towards you while sitting in the seat. Warm up the interior well first. Don't do it if it'* 40 F or below. It can be brittle.

they go inside the A pillar. when you get the trim off, there will be little holes in the metal you can see through there and get to the tubes

Disconnect the tube and run a rigid wire through it in case it'* blocked. Run a wire through from the roof into the A-pillar as well.

you can use air compressor if you cant find something long enough to get down the tubes

If the tube is blocked, you can blow it out. Not a good idea. These aren't designed to handle pressure.

It'* the corrugated plastic tube that looks like a typical split wiring sheath, but there is no split - that'* the pipe that carries the water. Mine was leaking right where it attaches to the corner of the sunroof. Fixed it when I re-did my headliner last summer.
