Rear sunroof drains on H3T

[factfive]

Upgraded my front drains on my T, now for the rears.Whats the easiest way to access the rears? Do I need to remove the rear seat? Or do I just remove pillar panels like front? Any insight on this thanks in advance.

Not sure on a T, but one needs to remove the seat belt upper mount, and a screw behind a round cover.

I just pulled it enough for me to get to the drain plug w/my hands; didn't remove the whole panel.

You can get to the drain hoses where they exit the rear cab wall. That’s about it…the rest is hidden behind pillar covers and headliner. Fold the seatbacks down. Remove the black plastic cab wall cover. It has a bunch of plastic clips in the middle and the top edge hooks onto some sheet metal tabs. Grab the panel from the holes near the seatback latches, and give it a jerk. Then lift the top edge off the tabs along the rear window. Then slip the middle seatbelt out of its slot.

Once you get here, you can reach down and unplug the drain hoses from the rubber bulkhead fittings. You can remove the bulkhead fittings from the rear cab wall, and clean them. The T-drains are NOT like the SUV drains. They are a simple 90-degree rubber elbow. There is no “X” to cut out but crap does collect at the elbow. Whatever you do…DO NOT BLOW THEM OUT WITH COMPRESSED AIR! This will surely blow the hoses off the fittings at the sunroof. Once this happens you must drop the entire headliner to reinstall the hoses.

I recently did this procedure to a customer’s T, and determined that most likely the hoses are not connected at the sunroof. There is staining at all four corners of the headliner, and the interior smells like a wet dog. After some head scratching I have decided to leave this task up to the customer.

I am going to recommend that the owner remove all the seats, console and carpet. Flip the carpet & pad upside down and lay it in the sun for a week. Drop the headliner and inspect the connections at the sunroof (add hose clamps if necessary). Clean the drain tubes out (with plastic weed-eater line). Then put everything back in place. It’s a DIY job for sure…it would cost a fortune to pay a shop to do this.

Not sure what to do about the staining on the headliner. It might be possible to use some Oxy-clean spot remover (laundry) and a toothbrush to gently scrub the stains. Be gentle as the headliner material looks to be fairly delicate. That’s all I got! Good luck.
