What a coincidence.

I am having the same problem.

3rd brake like dry as a desert and my floor is still damp.

Your best bet is to check the cab corners and back of the cab on both sides for holes that water can get into and make it's way to the front.

I'd also check for any small holes near the firewall.

So I reread your original post and the rest of what you've tried to do.

I am having the EXACT same issues as you.

I tried the 3rd brake light gasket, I've had the windshield and the heater core replaced...

Like you I also notice a very small, trickle of water coming down from the kick panel on the passenger side up past the fuse box. When I pulled the carpet back, I found what appeared to be a leak coming in from the firewall.

Just like you, after a night of rain, I'd wake up and my truck would be all damp on the passenger side.

I attempted to "seal" it as a quick fix with some rubberized coating, but it only seems to slow the leak, not stop it. I have the day off tomorrow and it is on my to do list to try to check the front side of the firewall.

Keep us posted on where you find the origin of you leak.

2nd leak location found.

I examined the rear window molding for possible areas that could lead to water leaks. I noticed a gap at the top corner of the window molding on both sides where an indentation valley runs from the top of the cab to the corners of the molding. (see photo) I plugged this gap area with some silicon to see if this would stop any leaks that may be coming from this area. Well then yesterday we had a monsoon - it poured rain for several hours, probably about 3 of 4 inches of rain in all. This morning I checked the cab and found no evidence of any water leaks coming from the back of the cab or anywhere else! I even drove the truck around for a little while, and still no leaks.

Hmm...interesting.

I'm down to try anything so I'll be sure to also check my own out.

In my case, I think it is coming from the front passenger kick panel at this point.

I think it is in the door.....

If you pop the hood and look at the passenger fender connecting to the hood that little crack.....follow it down into the engine wall. You'll see that there is a metal piece that just ends and leaves your door jam exposed. Now go on the inside of the passengers side door you'll see a piece of metal that looks like a shaft where water can just run down into the sidewall and leak into the vehicle. I believe this is where the water is coming in and leaving the mysterious puddle of water on the floorboard. So I am testing this theory with duck tape.....I believe it is the culprit because of the angle of the runoff.

Even though my leak appeared to be coming from the area near the passenger side kick panel, the leak proved to be coming from leaks around the rear window seal and 3rd brake light gasket. I fixed both those leaks and have no further leak problem. :)

However, after a hard rain last week I discovered about a quarter inch of water standing on the passenger side floor. Fortunately I have the vinyl floor covering, so no damage was done. After drying up the water, I had my wife spray water all around the passenger side window and door and the the left portion of the windshield but nary a sign of any water leak on the inside.
The next morning was clear and sunny and I drove the truck for about sixty miles. When I got back home I discovered a small rivulet of water running out from under the left side plastic kick panel where the fuse box is located. The water in both cases is clear and has no smell, so I'm sure it's not a coolant leak. I am really at a loss as to the origin of this leak as the water is leaking onto the passenger floor, even though it isn't raining. Also I was not running the a/c or the heater on the short trip when I again noticed the leak coming out at the kick pane. Does anyone have any idea where this leak could be originating. Thanks.
Hi Jono here i'm new to the Ranger Forum. I have a 07 Ranger with water leaks. i might have a lead on the water leak while vehicle is on a lean. I have the same problem with water build up on the passenger side floor. I decided to remove seats and flooring to dry out and attend to rust spots. While doing this i removed door seals at the bottom and then closed doors as a storm was about to hit. After rain had passed i expected to see some fresh water on the floor but there was none. Having thought about it i recall seeing water build up on the top of door seals at floor level previously when the seals were in place. It appeared to me then that the water was able to build up and overflow into the cab. I now feel that after todays discovery there may be a design fault with the seal . Does seem strange that no water got in while seals were removed don't you think? I hope this gets everyone a bit closer to solving this annoying problem.

inside the engine bay there is a drain hose against the fire wall , it may be clogged with leaves / debris , clean it out

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 of the cab to drain out the bottom. 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 will need to remove the blower motor from the housing under the hood. Then you can stick your hand through the housing and into the duct that goes up through the bottom of the cowl. About 1” below the top edge of the dam 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 gets 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
