Clear Sunroof Drains and Still Leaking?

That's what I'm experiencing. All four of my sunroof's drains have been cleaned and flushed using a combination of water, weed eater cord, and compressed air. Still, after I wash the car, I still get water dripping into the cabin. The drain system is clear, why do I still have water coming in?

Dang it! The dreaded "r" word. I haven't seen any signs of rust holes near the drains. Maybe I need to check underneath the pan. How do I do that?

remove the front headliner panel. Remove the dome light, mirror, sunvisors, and the chrome trim piece at the sunroof opening.

Damn... Which car are you talking about? The D or the SD? Are the drains in the same location on both cars?

I was frustrated by a tail light leak during all the rain we just had.

You guys are talking about where the drains "come out". Where exactly is that?

I'm talking about the D. The SD has slightly different rear drain exit locations. The D's drain exits on the front are near the front doors, coming out of the fender area. The rear exits are in the C-pillar. I believe the SD's front drain location is the same as the D's location. The SD's rear drain locations are near the rear wheels.

sunroof drains?

they are prone to rust out fixed several with apoxy and copper pipe covered the rust with apoxy ,no more leaks. take the whole sun roof system out repair and put new seals back in , hard to fix right in the car , you can take the whole head liner out without damageing it un snap clips and pull tensener rod out, then you can see the whole system ,

Mine are all clear in the white wagon, and I inspected from and rear connection points into the rubber hoses that come off the metal sunroof drain tubes.
My sunroof still will leak in a car wash, and not just a little bit. The drains just can't keep up with a certain volume of water.....
