good day, folks.
So, i have a lot of water pooling at my feet. A lot of water! I know that this issue has come before and is rather common. I have not yet had to deal with it. I have tried searching the forum for the old posts regarding this problem, but i couldn't find anything. Maybe someone with better searching skills can help me out. Some first hand practical knowledge sent my way would be appreciated as well. I know that i need to do some caulking somewhere. But i don't know where. (I do think i'll have to take the quarter panel off. I really don't want to do that).

Secondly, I am also very concerned about mould. Im thinking that ill have to rip out the carpet. But in the mean time i need to dry the area out. Any suggestions on how best to do that? I put a space heater in there one day, but that didn't work. I have thought of putting a heat trace through there with copper wire and a battery, but that just seems a bit sketchy. My other idea was to use a tiger torch to dry the area out. A bit sketchy, too. I don't think my ideas are very safe. Please help.

Shop vac your carpet and hit it with a mold inhibitor spray (home depot) to get the carpeting mostly dry and hopefull prevent mold blooms. You may have to remove it and just pressure wash it with clean soapy water and vacuum it dry.....after you find the source of the leak

The water can get in from a few different places. Here's a old thread on our forum from 2011. Next time try google search its more effective than the search function in our forum.

I noticed my drivers side floor was wet about 2 months ago after a thorough washing. Just last Sunday I decided to take that corner piece off of the front end to have a look at the seam. I couldn't get to the screw under the windshield seal, but even with only that holding me up I had a good look at the seam sealer there, and it was pliable and looks as good as new, so I put it back together. What else could it be? I know I had been spraying a lot of water around the windshield gasket, so maybe that is the culprit? Thankfully my Delica lives indoors, so the leaking will be kept to a minimum, but I would love to recify the problem anyway.

Little interesting note. When I had my 1990 US spec L300 the windshield was glued in, and had stainless steel trim that clipped around the edges of the windshield instead of the gasket type windshield in all of the Delica's I have seen from Japan. I wonder if it was due to a US DOT regulation that said the windshield had to be glued in. Must have made it more difficult to make two different surrounds for the windshield opening.

A small hole drilled through the floor at the lowest point helps. Doesn't stop water getting in, but it does allow it to leave...

Yeah, I thought about drilling a small hole. I haven't done that yet.

I'm not sure if this is the result of the same problem but, my right turn signal is indicating at twice the speed now as the turn signal on the left. Not sure if the water getting in behind the body of my van is causing any wiring problems. Maybe? May be a gremlin?

Could be just a burnt out bulb too...

Yup. That's what it is. I decided to check that right after I made the post.
I guess I'm just expecting the worst right now.

AHH Standard L300 leaking. I had a similar problem. There should be a few old posts about it but it could be one of two things.
The front window seal is leaking. Usually in the upper corners, that or, behind the front quarter panel. Behind it is a weld that seems to sometimes start to separate. The former always seems to be the more obvious.

With mine, I just cleaned it and ran a bead of clear silicone under the seal. I did the drivers side with a bead about 2-4" down the side and 10" along the top. That did the trick for me.

Another issue I had was the windshield washer hose came off on the passenger side. Water didn't leak in but when you hit the squirt button...
Well I think you can visualize. What a bugger to fix. You will need at least 3 hands one of which should be on an arm at least 2m long. If that is the case, take the time to wire them on so they don't pop off.

On a side note: I notice that one of my windshield squirt posts is loosening. I don't notice a water leak inside yet, but will keep an eye on it.

I had a leaking problem on the driver's side. Yes, Chris that one screw under the windshield gasket is difficult to get at. Once I removed the quarter panel, I cut off the sealant and liberally put 3M 5200 on, thinking that would fix the leak. It did not. Next, while I was having the front painted, we removed the windshield and found that the windshield gasket had shrunk. And there were obvious signs that water had been getting past the gasket. So we replaced with a new gasket and not only did used the rope in method(the Japanese style gasket) but also glued as well(US spec gasket).

My rear window gasket and left rear quarter have also been replaced. The rubber is old on these cars now, and seals don't work anymore. I am about the replaced sun roof gasket and sliding window gaskets.

As far as the OP's question on drying out, pull the carpet up as best you can and use a heater, or tungsten work light to dry it slowly. Something like lysol or similar will stop the mold. Mold will produce rot in the carpet, a bad thing. Also, make sure the floor boards are rust free(wire brush and paint) then seal the seems with 5200 or other sealant.

I've had the leaks from the front welds, but also could see a water line along the inside of the "a" pillar. I tried to stop that one by liberally sealing the windshield, to no affect. Further search revealed a rust bubble on the roof that was letting water in and running along the roof to the front of the vehicle.

I really need to remember to tack of this problem when it is not raining. It can be frustrating living with myself.

I had the water down the side, and wet carpets. It was the weld area that the factory original sealing had become old and cracked.
The following is basically how I repaired it too. I did use some tools to get every ounce of old sealant out before I put in the new. I used 3M all-around autobody caulking to reseal.

Just something for you guys on this topic. Go to a Marine store and pick up a couple of boat plugs, find the lowest point on the floor pannel, create a divit in the floor using a ball peen hammer, drill hole and install boat plug. Next time you cross a river or get water in the van pull the plug and watch the water drain. Put plug back in once water is gone an voila. No mo wata in van and van is sealed so critters and rust don't get in as easy. Feel free to rocker guard the floor prior to installation to stop rust.
