Cab Leak

[Kernel]

I have a leak somewhere in my 91. It gets wet under the rubber floor mat and leaves the floor boards wet. You don't see any water on the floor until you lift up the mat like I said. Do these 1st Gens have a place that they like to leak or could it be coming down through the doors, the rubber molding around the windows sealing them on the outside is cracked and kind of dried up. Thanks.

Scott, they definitely have a tendency to develope leaks. I have seen several threads on this but till recently didn't have a problem myself. I had the heater worked on and now have a significant accumulation of water on the passenger side. I suspsect that the heater box which is also the AC box is leaking condensate.



I rather doubt it is your door seals but it could be if you have had a blowing rain. Do a search on cowl cracks and you should get some input. The water will eventually rust out your floor.

The fresh air vents in the kick panels are a known cause of leaks. Some owners have even totally sealed them off to stop this. The windshield gasket/seal comes to mind also.

It was blowing pretty hard, if you have seen the weather news, we had flooding. The leak is on both sides.

I had a leak in my 92 W250 reg cab and I ended up removing the floor mats and driving the truck around for a couple of weeks to pin point the source. It was a little loud, but I found the leak. Water was getting into the cab around the "LE" badge on the right side of the truck.



Good luck.

Mine leaks one day, and not the next. Have water running down behind my A-Pillar gauges.



I figure it's impossible to leak here @ the corner of the cab... ... ... ... ... ... it's just my imagination.

Scott,

Just buy a wetsuit and wear it on rainy days.

If you have to you can install a bilge pump under the seat. :-laf

I'm serious guys. It only leaks on even number days, when rain arrives between noon and 7pm and when the wind is outta the west.



I'm thinking it will be easier to replace the floor with 1/4" steel plate than to trace this down.

you could do like i dun on the jeep, tear out the carpet and drill 3/4" drain holes...

or go over every square inch of the cab with clear silicone.

i'm no help.

Greenleaf - Remove the seat and take out the rubber floormat or carpet, whichever your truck has.

-Reinstall the seat and use the truck for a couple of weeks sans floor covering.

That is how I found my leak. I found that if I went out to the truck a night and shined a flash light around in the cab the wet areas were more reflective to the light beam.

I have owned (3) Gen 1s, a Gen 2 and a Gen 3 and IMHO the Gen 1s are still the best trucks.



Good luck,

After reading this I also noticed my carpet is getting wet, both sides, so this weekend its coming out. Has any one used one of those liquid roll-on bedliner products (Herculiner, DuraBlak, etc... ) on their cab floor. Has any one had it professionally "rhino lined"? Did you like it, hate it, did it hold up? I also plan to find the leaks, but I'm not sure if the carpet will be reinstalled.



Thanks,

Brian.

Jay Mon,



You happen to have a bilge pump, or shall I order a new unit from U. S. Boat????

Where in the cowl are they prone to cracking? I also noticed water laying just on the outside part of metal molding that the rubber mat goes under on the rocker panels. Any ideas about that one?



Scott

I too need an explanation on the cowl cracks. I was told that they crack where the factory stress relief is located. But the stress relief IS A HOLE. So that don't add up.

cowl crack

I guess I am the one who brought up the cowl crack issue but I can't help other than to say that there was a discussion last year and a picture showing a large cover sheet on the cowl under the fender (fender removed). Looked like a heck of a chore to me.

Here are some pics of the cowl crack; the second is looking through the door opening into the fender, if the fender was installed. The last one shows the cracks, the second crack doesn’t show well but it is at the bottom of the banana shaped hole.

 

[Greenleaf]

Thanks for posting. I'm gonna take a look just for fun. So this will allow water to enter into the cab???????? There is already a hole there from the factory... ... ... ... .

Another area of leaks that I found is around the bottom of the interior door panel. If you look at you vent panels after a rain you might see water drops around the speaker holes. Also on the bottom of the panels where it butts up to the to the door by the sill plates it leaks. I put a little bead of silicone around the bottom of the panel and got rid of this leak.



The next leak I have to fix is the quarter vent windows on my club cab. Need to replace the weather strip, Dodge should be shot for this one. They put the screws holding the quarter window into pop rivets. On half of mine the screws just spin and don't come out. I'll have to cut the screw tops off and drill to get them out. Nothing is ever a simple fix.

Hi Guys,



I just went through this over the summer with my '92 that I bought in May. Of course I checked everything I could find here in the forums (cargo light gasket, cowl cracks, kick panels, etc. ). While they looked promising I still had soaked carpet, which became more of a worry to me after I replaced it. After some investigation, I found that it was coming in around the winshield gasket on the top passenger side, but was following the gasket down to the lower right side of the winshield frame. You can take the glove box out and you should be able to see water tracks starting around the winshield frame if it has been leaking.



Fortunately, I live where tar and gravel roads are common so it didn't take long to wind up with a crack in the glass. Since my "large midwestern insurance" company that I also happen to work for has top notch glass coverage, I had the winshield replaced and specified that the gasket should be replaced as well. The glass company didn't want to replace it even though we(the insurance company) was paying for it. Well, it leaked even worse. Long story short - I had them redo it with the new gasket and it doesn't leak even while pressure washing since then.



I noticed the whole winshield was sagging downward along with the gasket, which likely was caused in part by the rather stiff ride. This was letting the water in at the top.
