New member here. Yes I have searched this issue and read numerous posts, but I can't find my solution. I have a 99 Cruiser with 176k miles on her which I have owned since new. I park outside on a driveway which slopes upwards. When I park nose inuphill the carpets in the rear near the tailgate get wet when it rains...I have seen it pouring out of the rear AC control panel. When I back the truck into the driveway with the nose downhill, the front carpets get wet when it rains...apparently running down the A pillars. I removed the sunroof glass, and have snaked out all four drains. I poured water in each one and they flow fine. One of the front drains was a little slow, but once I snaked a 14 gauge electrical wire in the exit it runs fine. I can fish the wire from both rear drains all the way out to the exits. The front drains get snagged up on something when fishing from either direction but they flow fine when I pour water into them. I removed the headliner. I can see water running down inside of the rear drain tubes, but I also see water running outside of the plastic pan and onto the top of the headliner. I can not figure out how some of the water is bypassing the tube and getting out of the pan. The plastic pan does not seem to be cracked. The drain tubes are securely fastened with a clamp and the water is not leaking around the drain tube. This happens in both the front and the rear. Does anyone have any clue how water misses the drain tube and exits the plastic pan??? Thanks for your help.
