Disco2 sunroof drain tubes good outcome

[alzerom]

2004 Disco: purchased used with small headliner droop over passenger's right shoulder. I have 2 sunroofs. This spring we had heavy rains and my overhead map tray got wet. I was expecting trouble, lots of trouble. I used an air pressure hose and blew out the trays. some vegetable matter flew out but I couldn't see much else. I did not blow air down the drain tubes as high pressures could uncouple the drain hose from the tray. Next I poured a quart of water into the tray on the left and it all ran quickly out the bottom. On the right side though, the tray ran slowly then more quickly and finally full speed. I got down off the ladder to look and found a pile of sand below the drain tube. Then I remembered it was a Florida car. The right sided obstruction was probably the cause of the headliner droop on the right side. Thanks for all the posts. Saved me a bundle for sure.
