Water under the carpet - Driver side

[SayleBoat]

Having water leak issue as well on my '22 F-350 Tremor. Water is coming down the A pillar and dripping from the bottom of the grab handle, behind the hood latch release and into the floorboard. When it rains it pools in the floor mats.

Have an appointment for service next Friday so hopefully they can diagnose and correct.

What you describe is commonly associated with a sunroof leak. Does your truck have a sunroof?

No sunroof!! Weird, right?

 

[Jrod250]

Probably coming from clearance lights. I avoid sunroof and clearance lights. Less holes, the better

Cab lights are sweet!

After a few days of big rain two weeks ago I discovered the conduit tray on the driver side was full of water. Rubber floors, but I could feel that the fiber backing on the carpet up at the firewall, behind the pedals was also a bit wet. Truck was parked in my driveway at a 5% incline, so I don't think it was the sunroof or the back of cab. Pass side was dry as a bone. Headliner was dry.

Can't tell how much it happens with regular rain. This was after days of light rain with a few big storms thrown in.

Did you get the leak resolved? It’s been raining in California and my foot well is soaking wet and some moisture in rear driver side carpet near rear door. I sat in the truck for 45 minutes while it rained pretty hard last night and I couldn’t see any water coming from “a” pillars or anywhere. I opened the door and there was the water. I’m going to try doing the door panel repair like @Jrod250. Hopefully this works.

Have not sorted it yet, holidays and vacation got in the way. I can say only happens when parked nose up in my driveway at 6% grade. No issue when parked flat.

Local dealers all want 2weeks to diagnose and address so needed to get my backup car ready .

So my truck is leaking too! AARGH! Noticed a wet towel odor recently and knew something was up. The channel beneath the kick-plate beneath the rear driver door was full of water, soaking into the pad beneath the rubber mat. I vacuumed a quart of water out! The wire harness was in standing water in there. I haven’t even looked under the front one yet, but I’m pretty sure it’s originating from the front. It’s my only ride, so sure don’t want to leave it at Ford, but need to hold them accountable.

Yep, exactly the same as mine. I could feel damp leading towards the firewall.

Insult to injury, I'm pretty allergic to mold and we are on a road trip and my allergies driving my own truck are off the hook.

That channel is continuous, so water can travel back to front, front to back depending on how the truck is parked. Was there enough water in the channel that it could have filled and then soaked the pad, or do you think it came in somewhere up front (windshield, clearance lights, sun roof...) soaking the pad and ran down into the channel?

I have said this in a few other posts regarding leaks, so I apologize for repeating myself...BUT...do what I did on a non-superduty:

I did this on a 2005 Hummer H2 SUT and fixed the issue myself - I would follow the same process if I had a leak on my truck. I will also say the truck was under warranty at the time, but I didn't want to deal with driving 2 hours to the dealer and leaving the truck there for a week.

Find the wet spot (heh) and then wait for a sunny dry day. Park the truck on level ground (asphalt is best so you don't get muddy hopping in and out, but not necessary).

Take a garden hose (rubber tip is always nice to the paint) and place it where you think the leak may be coming from. As the water is pouring over that area watch the wet spot inside the truck. You may have dried that spot up (which is best) and you will see the water reappear when you have found your leak.

For the HUMMER I thought it was a running light, sun roof, or door seal. It was NONE of those. It ended up being where the wiring harness left the body and entered the front doors. I removed the harness boots and sealed the area with RTV silicon. I then replaced the boots and ALLOWED them to dry before trying it again. 3 years later never had a leak.

That truck had carpet and the padding that I needed to dry out, and for that I pulled it back and vacuumed up the water, then placed a small dehumidified on the back seat on top of plywood. I ran the extension cord out the rear window and then tossed some silica packets under the pad. It probably would have been fine to just leave the doors open on the hot summer day, but I didn't want to do that.

*and now I will never have a truck with carpet!

Good luck!

Yeah, I believe the channel filled up enough to then soak into the floor mat pad. There was a quart of water in there. I believe it is coming from up front somewhere, maybe at the firewall, or even possibly down the front pillar. Probably going to need to dive into investigating it, like Vermonster has described. I just don't have the time for this kind of shit. Trying not to be angry. Would prefer to hold Ford accountable, but that involves time too, and an alternate vehicle, so it may be best to attempt to solve this myself.

You sound like me - document the hell out of it with photos for Ford. I will say, I have seen defective windshields do this (Jeep/BMW). If it was me, and I had water in the channel (exactly where it was on the HUMMER) I would start at the top and work my way down. If you have an LED camera scope, like this: https://www.amazon.com/Inspection-W...cphy=1027455&hvtargid=pla-1416820149314&psc=1 that can be handy do run down sunroof drains. I have not tried this on our truck, though. I was SO surprised when it ended up being the harness boots. I would have put money on it being something else.

I had a vehicle with a bad leak years ago. Turned out to be an issue with many from early production. Any rain and the driver and passenger floor would get saturated. The fix was filling the corner seams between the dash panel and a-pillar with some form of RTV/sealer... Not high tech by any means!!

Same here. Found a bit of water in the driver side rear door, seemed like the door panel was the likely culprit. Was going in already and they pulled the panel and low and behold, seal not done right. Fixed it and the tech noted he pulled the other panels and found passenger side rear also not sealed good and fixed it at the same time. Had not yet noted water there, but would happened at some point I guess.

Thanks for chiming in. I guess I’m not following you. My doors have a drain hole that is below and outside of where the door contacts the weatherstripping. Did you have water coming in at the bottom edge of your interior door panel?

I posted photos of the area. Post #6 on the first page and a description of what was going on

Thank you! I should have read through the whole thread again. I’ll have to check that. It could quite possibly be exactly where my truck is leaking too.

The vapor barriers can leak and water will run out the door panel as shown in Jrod's pictures. It runs down onto and then under the sill.

The photo below is just to show the vapor barrier where water can and does build up, leaking into the cab if not sealed properly.

 

[Parksoffroad]

Yes, mine was the water / vapor barrier above.
