You need to find the discharge end of the drain pipes. The ends are puckered to keep out insects. The pucker causes debris to pile-up and then water backs-up to the top and overflows into the ceiling upholstery. I trimmed off the bottom of the drain hose. I used a stranded 14 gauge wire to unplug the drain hoses by pushing up from the bottom. Do not use compressed air........ if you blow-off the hose at it's connection to the tray, you'll be in for some serious work to correct the problem.My wagon is almost ready for trips. Still trying to get my leaking pano roof sorted.. Gonna be dropping the headliner and rtv sealing anything I see that leaks.
