Recently purchased a 2010 Ford Explorer with sunroof. After a recent rain, I noticed the passenger side floor damp. Have checked the cowl and the AC condenser drains. Where does the front passenger sunroof drain terminate? Looks to be going down the A pillar but don't see where it ends. What's the best way to access the exit location to check for block/buildup?
Not 100% sure on drain termination but you can use a weed eater filament to push down the hose and check for blockage and see roughly how long it is and behind what panel it stops.
I ended up using a bulk piece of large clear bra made by venture shield and sealed my sunroof, but I never use it. Never worry about leaks now.
Took a look this morning from some research I did. Removed the right side kick panel and determined it drained behind it. Looks to be free of blockages/kinks.
But, also found about 12 oz of water in the wire track that runs just under the carpet alongside the passenger door. Got out the wet vac and removed as much as I could. Gonna have it go to the dealer for a once over.

I went thru this with my 96, from what I see, even in brand new models, there are a few variants of the basic sunroof design.
To find where the drains are, it is best to open the sunroof, then pour water in the tracks (the outer one under the seal). Water will pee out where the tubes terminate. It is kind of up above the rockers, that is why they rust.
The sunroofs drain into containers that are glued (butyl) or riveted to the ends of the tracks. Those connect to the drain tubes. It is normal to have water drip in the the tracks when it rains. As the truck gets older the sunroof seal may contract a bit and let more water in. This pushes the drainage system to its limits. You have to remove the headliner to see it all. Blocked tubes are one reason for a leak, but there are plenty of other leak paths.
I noticed one of mine was leaking, pretty badly at a seam (and the tube connector as well). I put roofing cement in the track, on the cracks, I guess it could be taken apart but I don't want to risk breaking it more. That stopped about 95% of the water. In very heavy rains (or with a hose), I still get a few drops. So I put one of those long soft thin plastic pastry trays that danishes come in. It catches the few drops that would go on the headliner, and it dries in a few days.
Well, after a trip to the dealer it seems an elbow with a one-way valve and a tube were missing. They thought someone had been looking at this previously. They were able to get replacement parts and now the floor is dry.
