Right behind the driver seat, under the carpet where the jumpseat is. I took the jumpseat out a while ago hoping to build my sub box into that cavity, been too busy and probably won't get to it. Is this happening because I removed the jumpseat? I was planning on putting it back in soon but the carpet in that corner is soaked. Any ideas?

 

2 door or 4 door supercab?

 

weather stripping not on right?

 

2 door supercab

 

I was told to check the 3rd brake light.

 

dang you beat me too it.

 

None of you are correct, sorry. If the third brake light was leaking, the headliner would also be wet.

Since you took out your jump seat, did you put the jump seat bolts back in? If you didn't, that is where it is coming in since the bolts go all the way through the floor pan. Put them back in and your water problem will be solved.


2 Door John, it is on the '93 he has.

 

Got it, thanks. Well, the bolts sound right. He might also have knocked out a rubber plug somehow with all the work he did. There's one right near the base of the B-pillar, just to the rear of it. I use that one to bring in cables and so forth for antennas.

 

Thanks Maurice thats gotta be it, I put one back in and I broke the head off 3 of the bolts but there's still 2 holes unaccounted for

I know which plug ur talkin about cuz I used that to run my cb antenna cable thru! But I made sure to seal that up after, so I'm with Maurice about it being from the holes from the jumpseat

 

No, not always. If it leaks just right it will drip straight down and appear to be a window leaking. My headliner stayed completely dry when mine did it. And I know it's a different animal but we have new body style Dakotas that puddle water on the driver and passenger front floorboards because the third brake light leaks down the side of the metal and runs below the sill plates right to the floorboard because it's the lowest point. I've seen some weird crap with water leaks.

 

Just a thought:

If you have a sliding rear window, like I do, mine was leaking through the latch, I saw it in my rear view mirrow drip while it rained. My cup holders in my jack cover would fill with water.

I had to pop the pin out of the latch, remove the latch, unscrew it (the screw that goes through the glass). It was still wet inside the latch from the last rain. I filled the screw hole with silicone and put it back together.

OK, that was fixed, then a few months later my 3rd brake light started leaking. Silicone once again, done deal, dry cab (except for that damn leak under my stearing wheel).

 

if your windows behind your doors are the pop out style check the grommets on the bolts that hold the windows in, also you can adjust how tight they close on the latch, mine were letting in alot of wind noise because they were not fully closed with the latch in the lock position.

 

Well since I've noticed this problem I pulled off the 3rd brake light and stuffed it with weatherstripping and plugged up the holes in the cab from removing the jump seat. But the other day we got a real bad storm and I still had a hefty water leak puddling on the pull out cover I have over the jump seat area behind the seats. Therefore it's gotta be the rear window.

Apparently there's a bunch of threads on this and from what I've gathered it seems like everyone just applies clear silicone to the rear window gasket [aside from taking it to a shop]. I want to do it right the first time and never have to worry about it again.

So my question is, will simply applying silicone to the outside of the truck underneath the rubber that goes around the window be sufficient? Or would it be more reasonable to remove the rear glass and re-seal it at this point? If so, how does one remove the rear glass?

 

sorry to say but i put an aftermarket 3rd brake light in and it leaked into my cab, 2000 reg cab, and the headliner wouldnt get wet if u look at it by removing the brake light you will see that itll tunnel into the cab without hitting the headliner, i just took the brake light off and put silicone in there and as far as i know it doesnt leak anymore, i dont see water dripping anymore

 

I dont know about the rear window, but before you go and put all the money into it make sure it isnt the brake light. I had to reseal mine 4 times before I got it to stop, I ended up packing the whole light with silicone to seal it.

 

I hope it's just a fussy brake light cuz that'll be way easier. As I mentioned I already stuffed it with weatherstripping and it appeared to be fine just from observation. Did you just apply silicone all over the reverse side of the brake light?

I'll try to get some pics of where the leak is coming from and maybe that'll help..

 

pics always help.

Yes, I took out the stock gasket and put a thin layer of silicone on the light, then I put the gasket back and then put alot of silicone on top. When I tightened it down a bunch squished out so I had to clean that off. That seems to have stopped it, I still have water stains in my headliner though.

 

For the sake of informing others I'll let everyone know that I fixed the problem

I got a tube of the flowable silicone from advance, and ran it all over the third brake light and all around the rear window and inside the little crevices from the rear slider. Tested it with a garden hose and had no leaks, and we just had rain and T-storms all night and checked it and I have no leaks.

The flowable silicone is nice cuz its so liquidy, so when you apply to where some of the weatherstripping is coming loose, it leaks its way underneath following the path of where the water was coming in until it plugs it.

 

I Had An 03 Regular Cab That Did The Same Thing, Water Was Comming In Through The 3rd Light. Had Do Take It Apart And Water Seal It>

 

I just had to seal the 3rd brakelight on mine this Tuesday. I saw the cavity behind the light and put some silicon in there for good measure.
