OK. I know search. I have found over 17 postings for this, but still not sure if I have fixed it. I went to the obvious which seemed to be the leaking sunroof. I double checked the drain which had some dirt, but didn't seem to stop the drainage. I cleared the drain of any dirt, and poured water and see it coming from the drain holes in the rockers. No water around the sunroof seals, thank god. Poured water over the windshield and don't see any signs of leakage????

Question is? If the windshield was leaking where would the water be seen coming from, ie I have the carpet pulled and looking for it to be coming in somewhere around the firewall???

Any help is appreciated.
 
i could be wrong, but i've always heard that a wet passenger floor is a result of a leaking heater core; which will need to be replaced... can anyone else back me up on this??

Normally in an 80 it's the sunroof or windsheild. If it smells and feels like coolant then it would be the heater core.

To test the windshield have someone spray the front windshield with a hose as you watch the corners of the windshield where the glass meets the rubber gasket. It should well up in the passenger side corner and run down to the carpet.

ditto that but be sure to do it for a while and get the whole thing soaked. my FJ62 used to only leak in big rain storms... so, give it time and soak the whole thing.
 
My 62 leaked around a rubber gasket on the firewall where the AC hose passed through. A little RTV and it's been bone dry ever since. (It was the gasket behind the brake booster on the driver's side...more RTV fixed that.)
 
my windshield was leaking making the passenger floor wet, I could never recreate it with a hose and it stumped me for a long time. I looked at the sunroof and the door hinges, most of the water appeared to run down the firewall behind te carpet but unless I cought it right after a rain storm all evidence on the firewall would evaporate leaving only the soaked floor,

I finally had the windshield replaced due to a growing crack, water problem fixed,

if you ever do have your windshield replaced seach here first, there are some pitfalls onthe 80 windshield most installers seam to think the 80 does not need sealent because it has a gasket, it will leak without sealant.
 
Thank you for the replies. Def. not the heater core. No smell at all. Def. water. Happened after the snow storm. I think I may need to get the windshield replaced. Small crack in the corner, but sprayed with water (probably not enough) and didn't see anything, but it may take some time for it to soak down like you guys mentioned. Looked in the firewall, but can't see anything coming down??
 
I had the same prob and did all the tests here and finally looked at the rubber gasket around the door and there were three spots the tabs had come loose from the gasket on the forward side of the door. As soon as I attached the tabs and and had the gasket back in place the leaking stoped. Simple fix.
 
i now have a wet passenger side floor after some very heavy rain but the thing is, it is in the back seats. i will check the sunroof and the door gasket as well. grrrrrrrrrrr
 
wet...

Nemo,

I had the same problem on the driver side.

Did all the "checks" for drainage, kinked drain lines, etc, but still got wet after heavy rains.

Got tired of drying out the carpet, so I siliconed around the sunroof, and have been dry ever since.

I figure it's a pretty easy diagnostic tool to use...just silicone your sunroof and see if you still have leakage.

I don't think pouring water on the sunroof is enough of a "stress test" to rule out a leak there...but a torrential downpour is! :mad:

good luck.

:)

Where is the water coming from question has been asked over and over, but I'll throw in my .02

The sunroof drain tubes work very well, I cant see them getting clogged unless you park under a tree with the sunroof open, or some other non-normal situation.

I found that in the front corners of the sunroof is a little plastic peice that is screwed to the sunroof pan. It has a foam strip underneath, if that is not sealing well, water will run underneath it, down the interior trim, and onto the floor soaking the carpet ( had the headliner out to find the leak ).

This previous thread has good pics of the area in question.

Another culprit I found was the steering wheel tubing as it passes through the firewall, the rubber grommet has failed, hit a big enough puddle, and its water inside again.

If I still get water, I'll be looking into the front windshield as suggested.

can you explain what/where you siliconed the sunroof? is it still operational?
 
Peepers asked, "can you explain what/where you siliconed the sunroof? is it still operational?"

I just took a tube of clear silicone, and ran a bead around the perimeter of the sunroof, which effectively sealed the gap between the sunroof and the body metal.

I can't open the sunroof without destroying the silicone bead, but I figure that's a small price to pay to stay dry...I don't like sunroofs all that much anyway! :)

BTW, I got this idea from someone else here, but don't remember who.

I have to ask the question concerning the headliner. If it were the plastic piece leaking onto the headliner, then wouldn't I see some form of water damage to the headliner, or staining et cetera?
 
ahhhhhhhhhhhh okay. not sure i can deal with that... i wonder, will the silicone peel away easily if the carpet is still wet and i want my sunroof back?

what about getting a new felt seal on the glass? has any one ever done that?
 
a new felt seal comes with a new piece of glass, over $1K IIRC, you cannot get it seperately from Toyota, the felt is not meant to seal, it is meant to leak some and the gutters under the sunroof carry this water to drains,
 
CDan quoted me $250 the last time I asked about SR glass.
 
If you are parked on a slope, water may be coming from the windshield and finding its way to the rear seat carpets.

I put a bead of RTV (silicon) betwen the windshield and the outside rubber gasket along the bottom of the windshield. I have been dry since.
 
I have been exploring my New 96 LX450 and found the carpet extremely wet after a rain with the sunroof open. I heard correct…. However, one side is very wet, while the other side was the expected amount of wet after 20 mins of rain before I closed her up. however, after (1st week owning) a few more rain storms it seems like water on driver’s side is still lingering around, I shop vac’d it up today, and have rained often Soooo. Stay tuned, as I fix everything on this truck sllloowly from Ecuador…. Parts note easy around here.
 
?? what the question is: if the sunroof is left open it will allow water into the vehicle.

However if the sunroof is closed it can still allow water into the vehicle if it has sagged (dropped own) or too much water gets by the seal
then the drain pan can overflow. This is made worse if the sunroof drains are plugged.

If the heater core is leaking that could cause a wet carpet (but should smell like radiator coolant unless you've just got water in the cooling system).

You can use warm soapy water poured slowly into the drain pan then a short piece of weed wacker string to clean out the drains, do not use compressed air. The front drains dump water into the rocker panels then it trickles out of the rocker panels (via small slit drains) onto the ground, so don't expect the cleaning string to come out the bottom of the vehicle somewhere. The rear drains are difficult to get to and IME don't tend to get plugged but soapy water into the drain pan may help clean those also.

If the windshield has ever been replaced (incorrectly), that is a very common cause of water leaks into the front footwells. The fix is to have the windshield
resealed correctly.

Do some searches in the 80 Series forum for these terms: windshield leak leaks wet carpet sunroof leak leaks water
