Cant diagnose leak on drivers side floor

[soc_jones]

Hey folks,

I'm desperate to figure out how water is getting into my ranger. I'm going to list a few bullets:

* Seems most saturated along left side along line with the door. The whole floor mat isnt wet just a few distinct areas, some are pretty dry or just mildly damp.

* Does not seem related SSM 50603 - condensation dripping from poorly wrapper ac lines. It's definetly not coming from the central ac cluster, definetly not dripping on my foot, carpet behind the pedal is DRY.

* I can spray water on and around the door from the windshield it doesnt seem to make it more wore wet.

* I took it to the dealership and they struggled to show the water drip from AC line basiically had to run the AC for hours to see minimal condensate.

Well when does it happen:

I drove to the dealership (30 min) in pouring rain with AC blasting and the floor mat was dry and I felt stupid and went home. The next day it was still raining and I drive to work and parked in a garage and went back to my truck and the floor was sopping wet again. This makes me think maybe splash up water? Maybe something from the bottom? honestly not sure.

I am attaching a picture of the floor where its wet is circled besides these areas it doesnt seem wet at all.

Thank you for any advice.

Last one I found was on a 23 F-250, same deal as yours. Very difficult to locate. What I ended up using was a coworker with a wide open garden hose on the outside and me on my back on the inside with a thermal imager. I finally found a grommet with a bad seal on the firewall. Leaks are a bee-atch.

Some Rangers came from the factory with the AC drain spout plugged. It’s up on the firewall left side of transmission looking at it from the front. I had to poke a wire in mine to open it back up. I was getting water on carpets in the footwells from mine being plugged.

I had wet carpet in my 2011 Ranger. Dealership service department said was coming in from the cab lights I put on so the said they sealed them. Well why wasn't the head liner wet? I did some investigating on my own and believed it was coming in thru the cowl. I had taped over the cowl vents and my floor was dry. I took it back told them that. Their next check was that it was the door gasket. Still leaked, they checked it again and said it was coming in from the cowl. That fixed the leak.

Didn't you know that you giving them the answer, automatically moves that to the bottom of their things to check. We're just dumb owners and know nothing about vehicles.

I suspect the door seal is pooling water above the door and when it sits it follows the path (contour) of the seal to the floor
or
Windshield seal pooling water at the top left side and its seeping down the same path as above.

When you are driving - airflow across the windshield and seal stops the gravity feed down.
Is is parked in a garage @ home as well?

I had a '21 FX4. You might not believe this but same thing with me when it rained. There are 2 firewalls together. The robots were drunk and missed the welds. I put it in the shop and they tried to fix it from the outside. No good. Told me they had to pull the dash. I said no, and traded it in on a Tremor. Hope this helps.

Could it be the drain in the door itself?

 

[Muscleford]

The door drain is at the outer edge I believe so it should drain out over the rocker panel.

 

[soc_jones]

riding it around again the floor mat seems wet up running the AC + driving around on a hot day. I did run the truck for a while at home and could see no condensate drip.

But if clogged, then what.

I think you would hear sloshing water before you would it inside. The drains on my 2011 passenger side door were plugged I heard it sloshing and never got the floor wet.

Depending of the level of humidity, due to where the condensate actually drains sometimes you do not actually see it dripping.
It drains on top of the bell housing.
Ford did not design the Ranger firewall to make this easy to clean.

For Reference:
Here is a pic of it

So from bottom you have to reach up and around the Transmission to get to it and that cover over the end of the tube makes it difficult to actually get anything into the actual drain tube. It can be done but it is not easy.

Another member - found a easier but not easy way to clear the drain by removing the EVAP Temp sensor and using a flexible blow gun (wand).
I would suggest to use a (Borescope) to actually get a visual on the drain to see if you (can see) what is blocking the drain and possibly grabbing it with mechanical fingers (piece of foam) vs just blowing air into the housing (blowing it out of the way) only for the issue to return when it floats back into the drain port.
Unless you are lucky enough to actually blow the clog (out of the housing)


This is a (opened) up HVAC Housing showing the EVAP Temp Sensor and relation to the drain, just be carful with the wand of the blowgun so you do not damage the Evap. Fins
Note: Do not pull on the Temp Sensor, just let it hang out of the way it has the sensor wire attached to the evap fins

If mine ever clogs this is the procedure I am going to try.

2013 Focus ST. Drivers side. Never wet while driving in rain. Occasionally, only occasionally, wet while parked in rain. I gave up trying to figure it out years ago.
