I've got water leaking from the headliner of my 1999 4Runner

I got a little compressor today and blew back up the drain lines that run from the sunroof - and all that blew out was dust.

So I'm thinking the drain lines on the sunroof may have come loose from the plug.

Is it possible to just drop the front of the headliner?

Thanks

Moonroof Leak

Where mine is leaking from: Moonroof Leak

I removed a few of the screws from my roof rails when I installed my roof rack, and left them out because I'm dumb. Ended up having water come through those screw holes and soaking the headliner. Maybe yours are loose or no longer sealed?

Just something else to check.

Perhaps - it's the worst when the truck in parked. My sun visors are getting soaked - and they're a long way from the roof rails.

On some of these older trucks the seal around the sunroof leaks.

The only solution that has worked for me is putting blue painters tape around the sunroof during the rainy months.

Sun roofs are designed to leak, not be water tight. You either have a clogged drain(there's 4) or one of your drain lines have come loose. I had to drop my headliner to fix this in my 4Runner also. It isn't that hard, wort part is taking off the oh sh*t handles on the pilars cause they strip almost every time. Mine had a tiny leaf covered in a tiny glob of mud. But I had to drop the entire headliner to get it all squared away.

I agree. Check ur drains. I cleaned mine out 2 years ago. Open the sunroof and 2 are in the front side corners. It drains I between the truck and front fenders. You can see it when the front doors are open.

Mine leaked and the drains were clear. Turned out there was a crack in the front center of the plastic bezel that goes around the sunroof glass. I tested it by taping it for a recent storm and it was dry as a bone.

However, my leak was also centered in between the two sunvisors. So maybe your mileage will vary...

Edited for typos...

I had a similar problem and was convinced it was my sunroof but it turned out to be a bad seal on the windshield. I had the windshield replaced $225 installed because the previous owner must have had a windshield problem and they use a crap windshield and sure enough I have't had a leak now in 3 years

Turns out there's a little crack in the front center of the plastic bezel that goes around the sunroof glass on mine as well.

Have you tried to fix - other than the painters tape?

I'm thinking about getting it dry and then some black silicone.

I have not tried yet, but somehow you'd have to get a pretty good fill on the small crack. I was thinking black silicon would be the best, but I don't know how I'd apply it cleanly, maybe some kind of mini syringe?

I've heard people using superglue and I thought that some kind of thin epoxy would work well...

If I come up with something I'll let you know. Let me know if you figure something out in the meantime, I'm all ears.

Used JB Kwik 2 years ago, sun and cold cycles made it loosen.. i just redid it again 2 days ago.

Next time i'll probably use a flexible weater resistant silicon.

Sorry to dredge up an old thread, but I guess I don't have enough bona fides to start my own thread..

Anyway, I just bought my sister's old 2001 SR5 and the sunroof leaks and has apparently stopped working. She says it worked last summer, but has leaked for a couple years. From reading some "my sunroof leaks" threads, it sounds like the drains are probably clogged, but I can't get the thing open to clean them. Is there a way to manually get the sunroof open, or even just access the drains?

Also, should the sunroof even let that much water in when it's shut? I've got to tape the perimeter of the sunroof to keep water from dripping on my head when it rains hard. Could there be a gasket going bad somewhere too?

mine just started leaking....not getting past the rubber seal but where the glass goes into the frame, aquarium sealant maybe?

If I remember correctly, there's a manual crank option. Up in the overhead compartment/light thing theres a square peg that you gotta turn. I've never tried

I think that's only on the 96-98 models. Mine's a 99 and doesn't have it. My roof is stuck shut too, and the drains are cleared, so I just put some RTV gasket maker around the perimeter to seal it. I always laugh when I see people with duct tape around their windshields. The gasket maker will seal better and you can't even tell it's there. Costs less than a roll of duct tape too.
