ok, i have a 2001 2wd ranger ext cab. a few weeks ago i noticed a little water under my carpet, no big deal right? well i put a dehumidifier in it overnight and it was gone. since then it has been back twice. it isn't leaking from around the doors or from the body mount seals ( as far as i know) do ya'll have any ideas on where it might be leaking from or a good way to try to fix it ( put undercoating on the whole underside )

 

Some guy told me one time, that there is a little pipe that drains the condensation from the A/C or something like that... and if it gets plugged up, it will leak into the passenger side floor. What you do is find the hole the water is coming from and unplug it...

I have no clue as to where it is or what the guy was talking about, but my friend was having the problem and I just caught that little bit.

 

That some guy knew what he was talking about!

This is the contributor to a stinky A/C, and interior leaks.
I discovered this when trying to track down a musty old-sock smell coming from my A/C.
In this pic, I have the A/C blower fan and moter removed. This is a simple process, as you only have to remove like 4 screws and it just comes right out of the housing.

The drain is located directly above the word "Fluid" on my washer tank:


If you don't feel like removing the blower motor, just pull the rubber boot off of this drain hole and scrap inside with a coat hanger.
You can see the junk that had built up, gotten condensation on it, then started molding to put off the foul odor:

Also, notice the rubber boot in the above picture. This covers this drain hole, so it may not be immediately visible until you find the boot.

Here's a close-up of the stinky crap. While you're at it, you may as well check your A/C condensor for the same stuff!


Ford's design on the A/C drain is faulty under most operating conditions. Centrifugal force keeps any condensation, rain, or whatever ends up going through the A/C induction vents to the rear of the blower box, on the opposite side of the drain hole. Over long periods, build-up forms from the small particles in the water, and creates this nasty crap like I had. After cleaning that off, my A/C smells good as new!

 

is the water leak in the back? doesn't the 3rd brake light leak in these trucks? i know i get water on my jumper seat if we get heavy rain. I've never seen it drip, or see water around the roof/window seal, but the seat gets wet by the back firewall

 

If it was the 3rd brake light, your headliner would be wet - mine sure was!

 

maybe not the 3rd brake light if it leaks can be very wierd.

Where was this water at in the cab? if it was at all behind the seats its worth
checking to see if the 3rd brake light is leaking because thats probably the most likely
source of water (if its from a leak)

I wonder if he is getting the leak in the same spot I am...check out my thread to see where mine is

 

I just got done caulking my 3rd brake light because i had a 1/4 standing water in my ext cab part of my truck,blah!

 

Not necessarily. My 3rd brake light has never leaked. However, my factory-installed rear solid window leaked from day one, and the leak finally went away when I busted that window with a 4-wheeler and got it replaced.

Check the weather stripping around the top corners of the rear window on the exterior. The rain-strip along the roof channels water directly over this seal, and is prone to leakage, obviously.

 

i sealed all the body mount plugs and every plug on the whole floor around the truck. so far it looks to be like that was it. probably from the "no touch" carwash that shoots water under the truck.( knocks all the mud off though) i'll post again if it is still leaking. thanks guys for all the tips

 

Found standing water on the drivers side floor today after a heavy rain, all the door seals look good, no water anywhere else, never had this problem on any vehicle before so have no clue where to start looking

Any ideas on how or where that much water leaked in or what kind of shop to take it to?

Thanks for any help in advance

 

I finally found my passenger side leak!!!
i don't the truck regularly. it had about 4" of snow from a storm that took about 3 weeks to melt slowly and then lots of rain. ( wet winter finally)
When i did drive it, i found My passenger side floor had about 2 gal of water that soaked from front to back from a leak.
i checked the rear window, 3rd brake light, door seal, top and bottom of the window with the hose.i couldn't find where it was getting in.

I put the hose on the roof with the water cascading over the top right edge of the door seal and window. the water was also flooding down to bottom corner of the windshield, the fender, antenna mount and over and into the cowl vent.

I found the leak. the water was dripping down under the dash on the far right from the bottom of duct work. water was running down the electrical components that are attached to the right kick panel. if look right above the vac can that moves the outward & up to close air intake from the cowl. water was getting in there from two problems.

The fresh air intake goes up through the bottom of the cowl where all the water runs either to the left or right side to drain out. The air intake has a dam on it that projects about 1"" above the bottom of the cowl. They use a foam gasket to seal it. i can't feel any screws or bolts, so it must be a snap together design with the foam gasket between the pieces.
You can feel the seam and the gasket projecting inside the housing. It was soaked and dripping water inside and then leaking out the seam in the ducting on the far right down the kick panel.
The antenna wire also runs right over the top of hole in the air intake before it goes through dash. So if any water get under the base, which mine was it drips water down inside the same place the foam gasket was leaking.

You can't see in the damn thing, it's by feel. So i used my fingers and scratched all the foam out of the seam and then cleaned it well. I let it dry for a few days between rain storms.
I used a small 6" squeeze tube of silicone and could the tip in the back side (cab side) of groove and could run that only part way around. Then it's squeeze silicone on two or one finger and start pushing it into the groove and then tooling it all the way around the inside of the groove to seal out the water.

it dried for a day before the next rain. i checked it yesterday after work and it feels dry inside.

Hope this helps

 

Found out where the massive water leak happened
The rubber boot between the cab and the drivers door came undone, worked it back in place, no water on the drivers side floor
after a heavy rain
