Awesome video! Looks like I will be ripping the carpet and seats out of an F-150 to clean the carpet and fix all the potential leak sources. Videos like this make it easy!
Thanks for the comment, I appreciate it. When you're doing the job and if you get stuck or something, or have a question, let me know, I am glad to help you out.
Fantastic video. I have vacuumed repeatedly, removed my cowl at the windshield and troubleshot in numerous other areas of my 2007 Lincoln Mark LT truck. I was successful in identifying ONE leak at the third brake light before seeing your video. I disassembled, cleaned and applied silicone, successfully stopping that leak, but then weeks later, AGAIN with the wiring trays at the doors full of water and the return of offensive mildew smell. As many here have attested to, I too will be removing seats and all my carpet/padding, expecting to see a missing vent as well. I had a topper installed on my truck two years ago, and the problems began shortly after that. Thank you again for pointing me in what I know will be the right direction!
Ford should be absolutely ashamed of their vehicles now adays. I have a 2018 F150 that is leaking water in on the passenger floor, and from researching it I have come to the conclusion that it is coming from the a/c drain tube. And to get at that I have to take off the front passenger tire and the wheel well liner just to get at the friggin thing. I still have warranty, but I don't like how 99% of the mechanics treat vehicles now adays, they have the "not mine I don't care" attitude.
Thanks for the comment, it's not just Ford vehicles. Unfortunately, all kinds of vehicles have their own set of problems. If you have any questions, let me know.
I wanted to see how you removed the carpet around the center console and you completely skipped over it. You said you would show how in the beginning and then you didn't 😂😂😂 still very helpful and quality information so thanks
@@Motorcarnut idk, mine is original Ford glass, although it had been re-sealed previous to my ownership. I've heard alot of stories of these years leaking due to the way they formed the channel for the seal at the top corners.
Just to add...on older trucks like my 2009 I saw where potential water entry could be through the rivets located on top of the roof at both rear corners.
I have had issues with my 2017 lariat FX4. What I found was the rear sunroof drain lines were clogged and were overflowing the channel and running down the c pillars in the back drenching the carpet. I also had one door seal that was not sealing properly and filling up a channel where the electrical wires run. I cleaned the drain channels in the sunroof and the drain hoses, dried out the carpet, and drilled holes in the channel where the electrical wires run from front to back. That way if any water did get into the truck and into that channel it will not make it from the back to the front. Initially I could hear sloshing water in the truck and it turns out that it was the channel full of water. Problem has been fixed ever since I cleaned out the sunroof drain holes. I check them religiously.
Thank you for the very thorough video. I don’t know if I am missing the vent too but I am experiencing a musty smell after rains or car washes and have s tonneau cover. Admittedly I skipped through the video some, but you said you replaced the vent by pushing it up from the bottom...could that have been done without all the other work you did?
Yes it can, just by taking out the rear seats and trim panels in back of the seat to gain access to leaky vent OR if there is no vent, like mine, all you have to do is just slide a new one up into place from the outside under the truck between the bed and cab, a little tricky but can be done.
I have a 2018 f150 king ranch, and the passenger side has standing water in the very first part you showed in the video. My center screen doesnt work a lot of the time and I occasionally lose all electronics when it rains very hard
I have a 2008 f150. My driver's side carpet has been getting wet under the floor mat. The padding holds most of the water. I noticed water as well in the sill. I first realized I had an issue because on very cold nights my windshield was getting really wet from the inside of the truck. I need a rag to clean it. I don't know where the moisture is getting in from. Even without rain on mornings with mist in the air when I lift the carpet pad I can see moisture on the frame. I had a new windshield replaced about 10 months ago do you think it's possibly the windshield not sealed correctly or something else.
Very possible could be the windshield especially if it didn’t leak before replacement. Also see if the back drivers side carpet is wet too, it can be the vent like I showed in my video or the third brake light seal etc.
@@Motorcarnut the back seat isn't wet nor is the passenger side front or back. Also headliner doesn't show any water stains or wetness. I removed rear driver side sill and there is a small presence of moisture. Was thinking it might be going from front to back. The front sill had a small puddle. Not enough to cover the wires or anything but you can see the puddle.
@@Motorcarnut if you ever have to make a tutorial on the headliner I’d love you forever man. My truck has a leak on the rear brake light like you said and it’s drenched up there.
I'm having a similar problem on my driver side only driver side carpet is wet looks like I'm going to remove the carpet as well to see if I can pinpoint where the leak is coming from🤨
Thank you for sharing. I too have been chasing electrical ghost due to water leaks. I am curious if you have observed how the water drips from ac drain for those whom don’t have the 90’ elbow....the water drips from my drain onto flexible heat shield material and weighs it down on my 02 sensor possibly getting wet. Any ideas how I can secure the heat shield and keep it from sagging down onto the O2? Thanks so much. Liked and subscribed.
Thanks for subscribing i really appreciate it. Maybe you car use large flat head washers with small center holes and small screws with a little gasket sealant and screw them in a couple of places were its sagging to the fire wall. That should take care of it.
@@Motorcarnut thanks so much for the reply. I shall certainly give that a try. Appreciate you taking the time to make such a detailed video and sharing with the rest of us. Cheers!
A year later and this video keeps on giving. I’m beginning to think either my roof moldings, maybe even the actual body weather strips between the body and door may be culprits. Anyhow wanted to say thanks again lol Also do you recall the truck in this video having a subwoofer and or if there was an amp inside/under the center console? I have the exact same stereo head unit in this video but no sub. Thanks again..I will follow back up when I find the source(s) of the leak.
You mean the third brake light? Yes, if you know where the leak is coming from. Not so easy to find when everything is wet. In my case it was a missing cabin vent and everything was soak-in wet and would never dry. Mould and mildew are smelly and dangerous to your health.
I found my leak inside the cavity behind the parking brake handle. A rubber grommet fell out of a hole in the metal body that was below the drain for the windshield
@@Motorcarnut About 2 hours. I ran a garden hose at different locations on my windshield and watched for water to fill the wire harness cavity under the plastic cover. Once l isolated area, finding the leak was easy
well that sucks because I just removed that exact vent to put in a high output stereo system in my truck and I'm running the battery through those holes in the back LOL
What a stupid design . Who in their right mind would put two LARGE vents in the back of a cab where water and possibly exhaust fumes could get in if you have an exhaust leak . I had a roll of paper towels behind the seat the first time I noticed the water in the cab . My windows were fogging up when the truck sat in the sun I knew something was wrong . Long story short , it was the lamp in the back of the cab because the head liner was also wet , so I fixed that . Now the head liner is dry but after a hard rain in the back behind the seats is gets soaked . Starting to get mold on the rug . I found out about these stupid vents by ripping that carpet of the back of the cab . They absolutely are the issue as it was still all wet around them . Question : why the hell do we need this over engineered garbage in this particular truck when I have owned many trucks that did not have these vents ?
All vehicles have cabin vents but where there located and how they’re designed is another story. The cabin needs fresh air at all times for various health reasons. Fords design is poor and cheap.
Thanks, I try to show what you can encounter in trying to track down a hard to find leak. You can take bits and pieces of my video to try and track down yours.
In my situation it happened to be the cab vent in the right rear of the cabin behind the rear seats, it was missing for some reason. So i just bought a new vent and installed it. I explained how i installed it in the video.
@@Motorcarnut o ok yeah because I heard once that there was an amp under the console so I was waiting the whole video to see if there was an amp under there LOL. But my truck has the upgraded Sony sound system in it so it still might have an amp under there
@@Motorcarnut I asked this same question about 20 min ago before reading the comments. Disregard replying to that lol thank you again for this awesome video.
As i just told someone else could be the back third brake light or window seal too? Or front windshield? or maybe some holes under the truck exposed to the elements?
Yep this video was the perfect blue print for the job! Used it through and through. Got the windshield and rear windshield re-sealed!
Glad it helped! And appreciate the feedback!
Thank you for this!!!
My leak came gushing in through where the two sunroof glasses meet, right above the sunroof drains.
(2015 Lariat70k miles)$2225.80 to replace entire sunroof assembly 😢
Seems a bit high and really no reason to replace entire sunroof for a seal leak
Awesome video! Looks like I will be ripping the carpet and seats out of an F-150 to clean the carpet and fix all the potential leak sources. Videos like this make it easy!

No problem good luck and thanks for the comment. Keep me updated on what you find
After paying 70k for a platinum f150 I shouldn't have to deal with this!
I hear you. After 40 + years in the business I find all manufacturers have they own set of problems. No one is immune.
I totally agree with you

Today I discovered water in my ‘18 F150 on the passenger side, carpet drenched with water….. Ford keeps disappointing
It’s not just fords
Dude you did a good freaking job. I just dont have the drive to do that job. But i need to.
Thank you appreciate that! I know it’s not hard just takes time.
Thanks for the video.... It helped me find my leak.. my vent was pushed out by my tool bag I packed behind the seat... Thanks again
Great to hear it helped you. Thanks
Wow you are a patient man chasing a damn water leak. This seemed like a lot of work for you.. Thanks for such a great job and good video!!!
Sure no problem. Sometimes water leaks are difficult to tract down. Thanks for the feedback!
I wanted to see how you removed the carpet around the center console and you completely skipped over it. You said you would show how in the beginning and then you didn't 😂😂😂 still very helpful and quality information so thanks
Watch the video, you have to remove the center console as shown first. Sorry if there was a confusion.
Don't forget, if you have stains on your headliner (like I did), it is possible that your back window is leaking. (Like mine was).
Yes, that is very true but not as common unless the rear window was replaced.
@@Motorcarnut idk, mine is original Ford glass, although it had been re-sealed previous to my ownership. I've heard alot of stories of these years leaking due to the way they formed the channel for the seal at the top corners.
I would imagine that being kind of rare but anything is possible.
Just to add...on older trucks like my 2009 I saw where potential water entry could be through the rivets located on top of the roof at both rear corners.
@@Sheeeeeeeeeeeeiiitt I did hear of that but a lot more rare I believe.

I hear ya bro, maintenance is the key. Just some vehicles need above and beyond the normal but I love my F150

Getting my rear seat out is much harder. I have a 2006 king ranch
2006 is kinda different but shouldn’t be too much more work?

So you can’t get the vents back in from the inside thank you for your time
No, but it can be done from the outside with bed on.

You have to find where it’s leaking. Water and electronics don’t mix and what’s probably causing your problem.
a great video, well done.

Thank you for the tutorial. How do you take the headliner out?
You will have to remove all the vertical side trims , sun visors , dome light and the plastic fasteners that hold the head liner in place.

Thanks bro, that truck is actually mine and still have it. No sub and yes keep me posted on what you fine. Shame you still have a leak though
I’ve sealed my rear light and now only my driver side fills up with water after rain
As another person stated, if could be the back window seal too? Or front windshield? or maybe some holes under the truck exposed to the elements?
@@Motorcarnut It was my rear cab vents , tore the truck down to find them pouring water in when the hose was on
Take that light out clean everything with alcohol and use silicone on your gasket leak fixed you dont need to take all that stuff out

Check the driver door seal especially at the top near the roof line.
well that sucks because I just removed that exact vent to put in a high output stereo system in my truck and I'm running the battery through those holes in the back LOL
If you do runs wires through there make sure you seal whatever you remove or it will leak
@@Motorcarnut yeah I've been going through some ideas in my head to try and figure out a way to keep water out of there

Thanks, I try to show what you can encounter in trying to track down a hard to find leak. You can take bits and pieces of my video to try and track down yours.
Why didn't you put in a new cab vent? Part # is 9L3Z-15280B62-A. Gosh all that hard work to clean and dry the carpet only to use duct tape?
Of course I did, that was temporary until the part came in.
I made a video on the install of the cab vent too
how did you fix the first leak?
In my situation it happened to be the cab vent in the right rear of the cabin behind the rear seats, it was missing for some reason. So i just bought a new vent and installed it. I explained how i installed it in the video.
Where was the water coming in to even get into that vent?
I explained it in the video, it’s was bouncing off the tonneau and going straight in that vent hole.
Sorry I missed that. Is there a hole from the exterior of the cab (between the bed and the cab) that goes all the way through?
Yes as big as the vent back there.
But that was without the vent installed, with it installed of course no leaking anymore.
@@Motorcarnut so there’s a hole in the exterior of the cab as well the same size?
where is the stock amplifier?
It’s in the dash, my truck doesn’t have any external factory amps
@@Motorcarnut o ok yeah because I heard once that there was an amp under the console so I was waiting the whole video to see if there was an amp under there LOL. But my truck has the upgraded Sony sound system in it so it still might have an amp under there
