Fixed in under 5! Water leak in passenger side footwell Chevy Tahoe 

your explanation of the plugged cowl drain and how to fix it was the true explanation of how to fix the proble, Most of the other videos missed this, In wyoming its not water in the blower box but ice which seized my blower. Thank you.

I’ve watched cowl drain issue videos for a couple years now(probably close to 75-100 videos) and not once did anyone mention there was a removable duct behind the coolant overflow. Very helpful info. Screwing with this issue as we speak.

I been battling this same problem in my 04 Tahoe and it was drivin me nuts. I could not figure it out. But now thanks to you its figured. Thank you

2003 Z71, purchased new, 330,000 miles; driver's side leak dribbling down inside cover of the fuse box in the left dashboard you see when driver's door is opened. I appreciate your taking the time and energy to quickly show us the solution to the passenger side problem. Great camera work, lighting and narration. Next - a video on the usefulness of magnetized tools when working with small parts under the hood.

Dude I've been going crazy crazy all day.I have my Tahoe all apart, blower motor dripping water threw gasket, remove it.stuck my hand in there,can't feel or see anything. It's now midnight and I haven't inspected the flapper, earlier I was close thow.i knew around where the problem was and removed over flow tank and removed screw for the plastic piece you showed in video but I could of swear all I saw was like insulation so I put it back together there.I was going to buy foam spray,rubber spray sealant and blindly spray it in hole.now I will check it again what you just did.so there's hope. I don't want to have to cover it when it rains everytime. .externally grateful for video. Wish me lots of luck

Thanks. This was driving me nuts. Periodically out of the blue my caret was wet.

this was a great help to me... I will try this for my Tahoe and hopefully, that solves the problem with the leak on the passenger footwell.

I appreciate the video as I have same issue on 1997 Tahoe, but note, when I took this apart, mine was clean as can be, so I'm still searching for cause of water penetration on passenger side. Note, I also had to seal the windshield, which worked, but that not the cause of most water...

Thanks my 99 is leaking and I was thinking it may be the heater core but ill look into this first then check it with the water hose, thanks again

I'm going to try this, I've been through 3 blower motor resistors as when they are waterlogged they don't work the fan. Thanks this is great.

Thanks for the straight forward instruction. Great vid.

Thank you. This has been happening for years! I finally found you..... Lol. You rock!

I tried that but was not my solution thanks for the breakdown

I have the same leaking problem. Trying this on the weekend. Thanks bro. Good video

I have the same problem. This is the first video showing the vent drain access. Water enters behind the hvac box and firewall when raining or washing. I have a 89 GMC K1500.

Thank You, I've had my 92 2 door Yukon since new and didn't know that👍 I'm thinking mine should be the same. I was really thinking it was the A/C drain clogged which I can't find.

Great video! Had any water leaks under the passanger side when the ac is on? Thanks!

Whats the best way to remove the coolant out of that tank to get behind it and check?

Dont know if it'll fix my issue....but its a good video and something i didnt know about :)

Omg 😱 bro thanks 🙏 u save me $100 at the mechanical shop

Can you do a video about 2004 trailblazer repair for the power window? The cable broke. The motor was fine. Gaining skill to replace the cable in the system would be a great video...

I like your video I think I got that 95 Silverado with the same thing

Great video. Keep it up! Do you think this applies to cars in general or just for your vehicle?

I'm going to try this on my 1999 4 door yukon. Thanks guys!!! #newsub

I already subscribed cause this is great, if this is my issue then this guy deserves some head 😂

what if it only leaks onto the passenger floor when i have the ac on?

I've got a 2012 silverado 2500HD that has this same issue

THANK YOU SO MUCH!!!👌👌

Dude thank you so much, had this issue with my 99 suburban and this is gonna save my ass, you rule :)

Thanks for the info!

awesome video, thank you

Good video thx

Thx man 🙏

That's some American engineering. Makes you wonder if that's by design. I guess I should have bought Toyota...

What a joke

Why is this a thing!?!?! 🥲 I was going nuts thinking I was rusting out on the bottom
