Pax floor board wet (1 Viewer)

[ukaviator]

Hey Guys,

Floor board was soaking wet after some heavy rains a few weeks ago.
Consulted the search engine here on Mud and followed the suggestions of checking the drain tubes in the sunroof to make sure they were clear.
Did that. They werent that bad but cleaned them and blew compressed air down them to make sure.
Truck was parked on a hill (facing nose down), we had some rain and there was no water so I thought the problem was fixed.

Well this weekend the truck was parked on flat land, had a heavy down pour and the pax floor board was wet again. Not nearly as bad as the first time, but still wet. Pulled up the carpet and the channel closest to the door was full of water. Pulled the plug on the floor board, drained the water and now its drying.

Sooooo, where do I go from here?
Windshield has been in for years, looks new, seals all look new.


Thanks

I am in the same boat you are in

I have tried to feed a wire down the front tube, how far down should the wire go, i feed a couple of feet into the drain tube?
Should I be able to see the wire down by my running boards?

ukaviator,
There was that rare case where the clamp that fastens the line to the bottom of the drain on one truck was misapplied at the factory. That led to a frustrating diagnosis process. Only way to find out was to drop the headliner, so it's the last straw sort of thing if nothing else works.

Yikes please dont say that!
What else can I try?

Why is it the water ending up In the floor board and not on the headliner itself?

I can attest to the clamp problem. My truck suffered from this. i had to pull the windshield to get the fabric headliner material out from under the seal where it is glued to the steel. then pulled it half down to get at it. put a bit of silicone on the nipple, put the hose back on with a gear clamp instead of the spring clamp. No more wet floors.

So what else did you try before you took on such a pain in the ass project?
was your headliner wet?

I did not notice the headliner being wet. And the drain did drain out the slit under the truck, however it was also leaking arround the nipple where the hose attaches. I ended up pulling the windsheild because I thought I was leaking be wise the water was comming ou from under the dash whish. Bt what it was was tha damn nipple , the water ran down the back o he headliner , down the piller and behind the dash.

Hows does your headliner sit now that its fixed?

I know once you let the air into those things they never seem to sit right again and more often than not cause the rest of the headliner to start drooping

Weedeater line works to try and snake down the drain tube. I don't like using compressed air. If there is a blockage, the compreesed air might blow the drain tube off the nipple.

good luck

On my 80 the sunroof seal is at fault. Its shrunk over the years and allows to much water to pass through which overflows the sunroof tray and it drains down the headliner(Its molded so the water just runs over it) then runs down the a-pillar and ends up in the floor pan.

Having the same issue as UKAviator... no wet headliner, weep holes by sunroof are clear, water in driver's side floor-board only after heavy rain (passenger's side is dry). I ran some line down the drain and can hear it down at the bottom. Where should the line protrude from? Is there a nipple at the bottom somewhere? When I opened the most forward plug below the door a bunch of water poured out...
Thx.

The rocker panels have "little" drain slits which end up getting clogged, hence removing the rubber plugs to let it drain.

My Px side carpet is also wet after rains but it's due to a leaking windshield gasket/seal. I have a new seal and just need to find a mobile windshield installer remove the windshield and old gasket and to glue everything back in with polyurethane... Simple fix if he uses the right adhesive and enough of it... (something a previous windshield place couldn't comprehend after multiple visits)

My passenger floor also gets wet after heavy rain parked on flat at least.

The other day I went through the auto car wash and water started dripping like crazy from the corner of the sunroof shade onto my wife (hehe ) this was the first time it happened to me in the auto car wash so from on here I saw the thread on the sunroof pieces that warp and let water in. Now if that same general problem was leading to the water on my passenger floor that'd be cool.

I'll have to check out the other things discussed in this thread too.

Same here after this weekends heavy rains in Boston, prob 1-2 inches. I noticed first thing Monday morning when I put the defroster on that the pass window was all fogged as well as the windshield on that side. Turns out pass floor has 1/4 of standing water & it's going to turn frigid this week. Got home last night & it was 45, so pulled off the sill plate and peeled back the carpet to find goldfish swimming. Pulled the drain plug, tore out all the Jute backing & threw that away. Mopped up the floor and ran a fan for an hr our so to dry it out.

Ran the weed wacker string down, got some gunk, but it's too big to get through the little slit in the sill. Tried some air, but my sunroof deflector made it tough to get in there. It was dark and I was working with a flashlight, so that sucked. Didn't try pooring water down.

The great news is my floors are like new! See attached photo; the dark stuff is the glue for the backing. I knew I did right by buying a southern truck. (asides form the ongoing mech issues)

I have owned 3-4 older sports cars, the first thing I do is rip out the Jute backing and replace with a removable alumin duct insulation avail at Lowes. Always want to have easy access to check for moisture and to be able to dry it out. Be sure to pull enough of the backing up toward the center hump as that stuff will wick the water up!

Hmmm... pulled the plugs and left it over night and the floor board is still soaked. This may be the first seriously annoying design flaw I've encountered since getting this 80 a few months ago. Guess I need to pull the carpet and see where it's coming from...

 

[fe sus]

Well, it finally stopped raining and I was able to do some more investigating. It appears the water was following the CB antenna line through the firewall. There is a gasket there but it wasn't tight. I added some silicone to try and seal things up. We'll see if it finally dries out.
Not trying to hijack, just want to share what I'm finding for others in the future with similar problems.
cheers.

Update ---- fixed leak!

Been a while since I updated but thought I should in the hopes it helps others out ....

Jumped in the truck during a down pour to try and figure where the water was coming from ..... turns out it was from none of the suggested places but somewhere completely different.

Under the rear right sliding window there is a piece of black trim held in place with 3 plastic clips. The clips were not as tight a fit as they must have been when the car came off the production line 16 years ago so water was coming down the window, and leaking into the rear quarter panel through one of those clips (the one nearest the rear pax door).
The water was dripping through the hole, onto the the rear seatbelt housing, down the carpeted wheel arch onto the rear pax floor and traveling to the front pax wheel well where it pooled.

Fix: Took trim off (on both sides to be safe), put a blob of silicone sealant on the holes, put trim pieces back on, job done.
Total time: 5 minutes.
Cost: $2.00

Hope this helps!
