Hidden HVAC Vents in 2014 - 2018 Silverado Sierra 

The fact GM had air vents in their center consoles in the 2000s but not in these trucks drives me nuts!

There is a hidden tire under the bed too

I have a 2015 LTZ. My under seat vents were almost completely distorted shut. I made a "U" shaped metal piece to place inside the vent tube to hold it open. Also they were almost all the way under the carpet as well. I also took a 4" flat piece of metal and slid it under the vent. Leaving about an inch out to hold the carpet down. The rear passengers aren't complaining now.

Finally got my first pickup truck less than two weeks ago! A 2017 LTZ Z71 Silverado. It has everything, even a sunroof! But a couple of passengers were complaining the other day that they were a little warm in the rear cab, being in Florida and all. I wasn't able to find any hint of rear ventilation in the owners manual, so I was about to call the dealership when I came across this video. Yep, I found the little vents under my front seats, just like you said. Great info!

Omgosh...thank you for taking the time to post this. NEEDED info!!

Those are there for the heater. If you ever notice when you use the auto feature in a car the heat comes out of the floor vents, and the ac comes out of the upper vents. Those are not rear ac vents. But you can use them the way you described if you want to.

Great video man! Keep the 14 Silverado videos coming!

Dustin, thanks so much for all the info! Keep the videos coming.

It would be nice to have some "top: vents too.

Game changer! Thank you for sharing! Cheers neighbor I’m in Springfield mo!

I had a 2004 Chevy Silverado SS that I bought brand new. It was my dream truck and I regret getting rid of it. The reason I bring that up is because that had the rear vents. I was so disappointed when I realized that my 2014 Silverado didn’t have them. That being said, I never noticed the vents under the seat so thank you very much for this video. My five-year-old will be grateful as it gets pretty hot here in Florida.

Thanks for the vid. First thing I noticed AFTER I bought my ltz! Gm lacking in this dept.

Thanks for the info. I have a 17 Silverado didn't know about this my grandkids will appreciate it thanks again pop pop.

Thanks for sharing the tip!

Haha, thanks. I was traveling, and I was wondering why I was cold in the back this winter when the heat was on for feet. Now I know where the vents are. I can actually put a proper vent setup so it does get blocked by the carpet. Thanks

Learn something new everytime I watch your videos man keep up the good work nice truck by the way to expensive for me

Same on my 2004 Silverado extended cab.

Thank you, love your vid’s.

A lot of older Volvo's have that rear floor vent feature.

They have been doing this for years. . My 07 Yukon has it under the seat too

Thanks for the info! Have had my truck new since 2016 and my son always complains that it’s hot in the back seat 🤣🤣

That is one sharp truck

Thank you for the info!

When you put the hvac on floor you loose your recirculation. In the summer for max ac you run with recirculation on, gets alot cooler that way.

Great job

Yup on my 2014 LT Z71nice and cold upfront and my passengers in the back (my kids lol) always complain saying turn up the air cuase it's hot in the back but after a few minutes it cools down but never knew about the air vents on the floor thanks for the heads up

Do you know what the upgrade is for the center console that has the air vents for 2014 GMC sierra ?

Excellent! Thanks.

I recently discovered my 03 2500HD extended cab has this vents under the seats. Happen to found them by stupid chance when I was looking for something on the floor. Never knew there was vents under there for 16 years of owning that truck.

Yeah i was gonna say, most cars and vehicles will have vents under the rear seats, its much nicer if they put the vents on the rear console as they should in a 4 door truck.

Thanks man

Every vehicle with a rear seat has those.....so you still aren't getting your money's worth lmao

I agree with the option disappointment on the rear heating and air conditioning that sucks, and driving Chevys for 40 years what did the GMC dealer and bought a GMC and obviously they don't have them either so thanks for the video, yes Chevys way behind but that's all I've been driving

The reason those rear under the seat Vince only work when you have the settings on feet is because they are for your feet if you’re sitting in the back

Also looking for more information on the auto temp mode

My 07.5 has that feature!

great for them muggy summer days when your feet are hot

Hi got a 2015 high country they didn't change much looks the same as my interior . What's your fuel economy like I m in Canada so we I first got the truck it was 17 or 18 and the spec sheet said 14 liters per 100 kilometers Changed to a k&n air filter new plugs and wires battery sensor cleaned the intake with some seafoam in the fuel and now I'm ranging anywhere from 13.8 to 15.2 👍

Thanks bro

You should make a video on how to set the auto mode

What are those vents in the back of the seats

My 2010 silverado has those under the seats also

GM has done that for a long time. I think my '72 Impala even had the floor vent hidden under the front bench.

Suck it up buttercup! Max it out and enjoy the house payment!😂 (good vibes!)

THANK YOU

I’m a new mom and this helped me thank you

Been a GM guy for years, but GM has been behind for years when it comes to interiors and options. I say no, you didn’t get your moneys worth. I hope the 19s are better than the current generation. It seems like they are just playing catch up though. The vent situation is the same on the 2007.5-2013 trucks.

Dang I just bought a 16 rally edition silverado and I thought it didn't have none at all. Thanks

Hey i bought some leather seats from another gm truck for my Silverado and my driver side seat don’t work because of the seat reminder I don’t have the oem seat reminder but I wanna know if you know anything about it

I was def let down when I bought my Denali after driving my 06 Sierra 1500 SLT for years and discovered they had done away with the middle console vents for the back seat.

Tnx bud 👍

Most vehicles built from the mid 80's on all have that same feature

04 ext cab has those

I believe when you have it on auto heat blows out of the bottom vents since heat rises and cold air blows out of the top vents since cold air sinks.

You could mote than likely easily reroute those to some diy vents un yhe back of the console with some tubing

My 2007 was same way along with my 03 and 1997

When cleaning my truck I would see that vent and wonder what is was for. Now I know!

You would think they have them in center console like my old Yukon

I'm amazed that people are driving around in a 6,000 lb truck and don't know about this. My '01 had these vents.

The reason why the truck doesn’t blow cold air out of the lower vents is because heat rises. You blow cold air out the upper vents to cool the hot air in the cabin. These trucks get ice cold inside if you let it. I keep mine set at 68 degrees in our 105 degree summer days and it gets there quick.

Six years later, and I finally see this video about vents for the back of my ‘15 LTZ. 🤦‍♂️

Another hidden feature: long press the on off button for the radio, a whole different display pops up.

I have the same thing on my 2011, but I knew it was there.

I knew they was there but wish they kept the same as older trucks and vents on console. My 03 sierra slt crew dmax was great. 2015 sierra crew denali not as much. Yes air but at feet not up by body and non adjustable. Just think with all the advancement we have done to vehicle's that could totally be one. Especially in a crew cab. I've got rear blu ray entertainment center that nobody uses. Rather have good ac in back for them to use.

My 91 explorer has the same thing.

Anyone have a part number for this?

I could feel the air in your backseat!! Need to dust off your dash though.

My 02 Chevy Avalanche has those under the seats.

My 2002 Silverado has the same thing

Cold air sinks hot air rises so winter goes to the feet summer up top

Where the hell have you been, all ex cab trucks have that

Does the High Country ride any smoother than the other Chevy 4x4's?

Only been in crew cab trucks for 10+ years

Why does the AC always come on in Auto mode? It’s winter!

Those hidden vents are something else. Why would you hide vents? Lol

Those are heat outlets.....aim the front vents up and towards back...I do that and my grand kids say it's too cold......

That is mainly for your heat, not A/C

That has been there for years......

But my 14 Denali has vents on the back of the seats

Hey man I have a 2014 LTZ at 65k currently and have had zero issues With the AC thank God. Bought it from the dealership about a month ago. Question is do all 2014 have AC issues or are they more isolated issues? Thanks.

It's in my 1999 Chevy Silverado

Everybody knows about those dude!😀

My truck has that n also the top vents .

They are called floor vents.... my f150 has them along with vents in the console. Cool part about the f150 is the steering wheel isn’t 3 inches off center.

I'll take the rear passenger vents on the consule that my 2006 has over that floor crap

Those are for heat

Should’ve gotten the LTZ

I got a 2019 Chevy 2500 , I think something got in mine and it’s leaving a horrible smell that cause me to get a headache and eyes and mouth burn

My serious complaint on mine is the dang transmission issues lol

I think most vehicles have under-seat rear vents, as my 21-year-old Accord has them. My grandfather's 01 Silverado has actual console-mounted rear air vents though, so I guess Chevy decided to downgrade.

cant figure out why gm did not put real vents back there. the get so close and they get to the end and just "ehh just do whatever." im sure the 2015-2020 f150 had it. 2020 for sure has it.

my 06 SLE ECSB Sierra had rear vents on the console. IDK why they omitted them on the 14-18 trucks :(

Mine whistles from the front vents if the passenger side two are closed. My 2016 isn't as good as my 2006. 06 is a LS and the 16 is a LTZ

Idk about rear vents... As long as people fit back there they will be happy.

Well yea, just like a 4 door car most trucks have a floor vent. Not a face vent....

Well my feet will never get hot in my back seat. Because I never sit in the back of my truck. But the wife will be thrilled know the grandsons will cool feet going foward!

I was a little bummed about the vents when I bought my truck new. That was about my only complaint about the Chevy when I was comparing different trucks. I can honestly tell you that my family and I have never missed them. My kids actual complain about it being cold before I get cooled off good. Just run it in Auto at whatever your desired temperature is and let it do its thing.

There's a hidden engine too. Look in the trunk that's in front of the windshield.

I can not tell if you are being serious or not, first off every car has those vents, second the heat coming out of the back boards, is when you have the seats on cool, it will push out heat through the exhaust vents, put your seats on heat and cool air will come out.

my '97 Ford Taurus has those....
