Headliner Leak 2nd Gen Sequoia - Sunroof Drain Locations
Вставка
- Опубліковано 13 чер 2023
- My '14 Platinum started having a leak from the driver's side headliner near the "B" pillar area after heavy rains, so I decided to tackle the job of finding it. Most people say that the leak is from a clogged sunroof drain, but mine turned out to be a very odd source.
This video will help you troubleshoot this problem and show you how to take the headliner down partially. - Авто та транспорт
Great video. I have a 2013 Platinum and had some water intrusion last week during Hurricane Idalia. Some by rear hatch, some 2nd row passenger floor, and some rear interior lamp/headliner area. Found a few missing plugs and a few clips and failed caulk in hatch area and a missing plug in 2nd row passenger pillar where water would drain between door and body. Next step is to check sunroof drains, XM antenna, and other roof penetration to see how it got up into headliner area. Thanks for the video! Great job.
Yeah, I also saw the gap for the XM antenna and sealed that up with some black RTV. I couldn't reach the nut for it without bringing the headliner down in the rear (and I didn't want to create more work for myself). Hopefully you get everything figured out & fared well through the storm.
Ran into the same thing with XM antenna. Pulled the lamp down, thinking it was right over top and I’d have access to the nut. Of course I didn’t. I did wind up putting some white silicone around spoiler light penetration as the foam weatherstrip they used was shot. Need to get some black for the XM antenna. Good idea.
I’ve got a 2018 and the same “red rock” interior. My door panels have started melting at the top, near the base of the window where your left elbow would rest. Have you had this problem?
No I haven’t, but I have seen the problem with other owners. Most of them find the fabric and replace it themselves. There are some good YT videos on the process. If you’re on Facebook, join the “Toyota Sequoia 2nd Generation” group. A few people have done this in that group, too.
Hi! Where did you buy this snake? Can’t find something like it. Thanks!

Curious if this resolved all the leaking issues? I recently found soaked padding from the hatch/trunk area all the way to behind the driver's seat. Nothing on the passenger side. I've pulled all seats and carpeting (to dry out the padding) and went through the car wash several times to see if I can find any ingress. I haven't dropped the headliner, but reaching in at all four corners, it's completely dry. I suspect it's coming in via the hatch area, or through the floor. It's quite frustrating.
With the driver's side paneling removed (b & c pillars) I found the pink/orange drain tube for the rear corner of the sunroof, I pulled it out of the port at the rear fender from inside the cab. The end of the tube has 45° cut on it to get it into the mating rubber boot that comes out at the fender. Blowing into it by mouth offered quite a bit of resistance. It certainly wasn't free flowing - probably on order of a drinking straw. Just curious if that's how yours was. haven't hooked up a compressor to it, or attempted to add water from the roof yet.
Yes, I have not had any more leaks since that "fix". I also put some black RTV around my XM radio antenna because there was a slight gap around it. If you have the XM antenna, check out that seal and see if you have a gap.
So I guess you don't have a definitive cause on yours - other than that it wasn't a clogged drain. I'm going to soak the vehicle with my 200gpm fire pump while sitting inside with a flashlight. I really hope it's not in the ceiling as the thought of pulling the headliner is daunting, to say the least.
Incidentally, did you find any of the white plastic support/spacers loose? I've had two already separate from the headliner and create a tapping noise as they bounced when I hit bumps. I was able to pull enough of the liner down to reach in and remove them. I don't know how many there are in total, or whether you have all of yours still firmly attached. I have a 2011 Limited. Thanks. Subbed.

@@erkme73 At around the 19:00 minute mark, I show what the cause of my leak was...someone drilled through 2 of the 4 rivets on that metal crossmember. All four of my drain tubes were clear with no obstructions, so that's what prompted me to pull the headliner down for a closer inspection.
I can't remember if any of those plastic trays were loose, but it is a known issue in the 2nd Gens. Most people just pull them out. I think they're just for routing wiring up there.
@@hoopin4you I guess I missed that. I saw the RTV, but figured you were just being thorough. I installed a lightbar on min a couple years ago, and had to drill two holes in the gutter just ahead of the front stock luggage rack mounts. I'd already done it on my Tundra years prior to that, so felt confident that I wouldn't get any leaks from it. It was during those installations that I got a pretty good understanding of the mechanics between the interior and exterior roof construction at those locations. What I don't quite understand is on the rivets that you found drilled out, did they actually penetrate the roof on the outside? I would think that those rivets simply held the interior roof/ceiling beams together, but neither side went to the outside.
IOW, did the previous owner drill through the roof? You said you were going to blow it out to dry it before RTVing, did you find water in that space? Very curious as to how those holes interfaced with the exterior.
Incidentally, the rivnuts (rivet-nut) I used to install the lightbar brackets on both the Tundy and Sequoia have held just fine - zero leaks there. I can access the underside of both sides easily by just pulling the headliner down in those areas.
@@erkme73 No, there were no visible holes in the outside roof. I think those rivets are probably in the sun roof water track that goes to the back drain tubes. Once I poured more water in that track, then I saw where it was dripping from.
I love rivnuts...so handy to use and they do seal really well. On my '87 R10, I installed a 3-row aluminum radiator & converted to dual electric fans. I used rivnuts in the aluminum fan shroud to reconnect stock hose brackets...worked like a champ.
I want to install lightbars on the Sequoia (and maybe my wife's Tundra...she doesn't really think she needs one). But usually when she sees the mods I do on my Sequoia, then she becomes a believer. 🙂 I upgraded my headlights to VLAND full LED assemblies with iJDMTOY LED fogs, and when she drove it at night & saw the difference from the stock halogens, that was all the convincing she needed to install them on hers.
