One end of the drain tubes are connected to the sunroof track, but where are the other ends connected (front only)? I was contemplating replacing them whilst I solve other sunroof problems but apparently they are attached at the bottom end also? They just disappear in the pillar and I can't for the life of me find the other end. I squirted water in them but still can't tell where they are. Can someone please tell me how to reach the bottom end. It's an '01 King Ranch. TIA...
