Heat Not Blowing From Vents……

A friend with a 2022 tundra ask if I had heat blowing from the face vents. I said I hadn’t tried it yet. So last night I tried it my self when putting the heat to high and on face vents it’s very little air flow. I’m curious if some of you could try this and let me know if you also have the issue. I’m wandering if the timing of the blend doors is off a couple teeth.

 

In all vehicles with auto climate control it blows to the floor when on heat. You could test your theory though by putting it on cool and then if you have full flow from the dash vents you know it’s good.

 

It’s not on auto I tried many combinations and when on heat there’s barely anything from the face vents. Ac will blow out of face vents in multiple combinations.

 

Is the engine warmed up when you’re checking? The fan doesn’t blow as hard as the engine is warming up.

 

Go give it a try and you’ll see what I mean. I also know what you mean but this is not that I tried multiple scenarios. Idle, driving, different combinations like recirc/vent and pretty much everything I could think of. Sitting next to my wife 21 sienna it’s no contest the sienna blows it out of the water and I can’t understand why it’s so throttled.

 

OP I noticed the same thing on my truck this morning. Even with the little air flow it still heated up pretty quickly.

 

Hey all, this is my first post on Tundras.com. I finally received my SR5 CM a few weeks ago and I am having a similar issue with the heat not hardly blowing out of the vents when its cranked up. The vents in the back side of the center counsel for the back row have way more pressure then the front seat vents. If I set the temp to "Lo" or cold it blows air out like no ones business. If I have it set to "HI" it's like the diverter inside the dash that allows the hot air to flow blocks the fan pressure. Just wanted to follow up and see if this is a common issue or something I need to have the dealership look at? I have three other Toyota vehicles and none of them act like this.

Thanks

 

Just to confirm, are you all adjusting the airflow mode to upper vents only?

 

Yes, I have cycled through all of the vent modes and it doesn't make any difference. If I set the temp at 80 or whatever heat temperature and turn the air flow all the way up there is very little pressure but as soon as I lower the temp to LO it blows really hard.

 

Having this same issue, 23 TRD Pro

 

Mine does the same thing, more airflow from rear console vents on heat, maybe it’s by design?

 

I had my 2022 TRD heater fans looked at by dealer (Montana) today. The technician was surprised by the lack of fan power when switched to "Hi" in all modes EXCEPT defrost. Regardless the floor heater and dashboard fan vents barely blow out any heat. The heater works well, but the fans don't distribute the heat efficiently.

Technician is contacting corporate to submit a report in an effort to find a fix. Will update this forum if a noteworthy solution is uncovered.

 

Interesting. I have an appointment for next week to have the HVAC looked at in my rig. Hopefully if enough people bring this to Toyotas attention they will come up with a fix or at least address it.

 

I’m curious to see what if anything Toyota does about this. My truck also seems to have poor air flow, but seems to warm up efficiently. This may change moving forward as we haven’t had too many “cold” days yet. It seems like this is more of a design flaw on the new Tundra HVAC system vs a repairable flaw in individual trucks. It really seems like most trucks are experiencing the same issue.

 

Additional note: we checked the fan on another Tundra while I was waiting on mine to be finished. That Tundra's fans performed similarly (poorly). I agree with you RayRay27... if enough concerns are voiced at Toyota Corporate, a recall (fix) may be in order.

 

Is your air intake set to outside air or recirculate?

On my former 22 tundra when set to outside air, the air flow was reduced but when set to recirculate the airflow increased.

just an idea.

 

When I switch from fresh to recirc there is way more air pressure out of the face vents but not sure why it would be drastically reduced between the two? I have a 94 Land Cruiser, 06 Matrix and a 19 Highlander with dual zone climate and the Tundra is the only one that acts like this. In the Highlander, if you have it on the second to lowest fan setting, it will dry your eyeballs out after about 20 minutes if you have it directed straight at your face. In the Tundra, you have to almost go to max to get the same pressure.

 

that’s where I noticed the difference was between fresh air and recirculate.

 

I wonder if the routing for the air on fresh goes through the cabin filter & recirc doesn’t, and that is the difference?

 

That was my line of thought as well while I drove that tundra.

 

FYI, my 2011 CM SR5 does the exact same thing. Just played with it on the way home; with the fan on high, the combo vent and floor setting. If I maxed out the temperature the fan speed drops a lot, moving it to the middle or to cool blasts the fan. Seems like a planned feature.

 

Noticing the same issue in my 2023 Limited Hybrid. Wondering if it’s a design feature of some sorts, but if not hopefully there is a fix!

 

Here’s a related thread. Post #35 indicates they’re looking for a fix.

 

my airflow is weak but man it heats up fast.... i usually have to turn heat off on a drive over 20 min

 

I got my truck in the fall in the south which is a mix of cool to quite warm. I have to run the auto temp on 67 which is the lowest personal default setting I have ever had to use in any vehicle. All others have been a 69-70 as my default. So the HVAC on this one does seem unique in performance.

 

Took my truck into the dealership today to have them look at the HVAC plus a few other issues I am having and they said that the HVAC is acting in the same fashion as two other Tundras that are sitting on their lot currently. My next step it to start a case with Toyota to address the issue. If you are having the same issue please call 1-800-331-4331 prompt 7 then 3 to report the problem. They answer pretty quickly.

 

I’m curious as to why it is assumed the reduced flow is a design flaw or defect? I would think the purpose of the heater is to heat the cab. Is the cab being heated? If no, then there’s a problem. The method Toyota uses to accomplish this may be different than what most are used to; different doesn’t always mean wrong.

 

I currently own three other toyotas and my dad has a 2012 FJ Cruiser, the Tundra is the only one when you turn on the face vents literally nothing comes out of the vents. This can't be by design.

 

Again, you are making an assumption this is not by design. So your are stating it must be a problem because it doesn't respond like your Dads 10 yr old different vehicle? Go on the Ram 1500 forum and listen to people complain about the a/c not cooling to their liking and comparing it to their previous Rams or even completely different vehicles. I had a ‘19 Ram 1500 and the climate control worked for me. It didn’t always operate like other trucks I have actually owned, e.g. ‘17 F150 3.5 EB, ‘14 Ram 1500. Point is, it cooled/heated the cab as required albeit maybe not as “forcefully” as I was used to. I’ll ask again, is the system heating and cooling? If the answer is yes, whogas how it accomplishes this. Isn’t the point it actually does what is supposed to do?

 

I’ve had several Toyota’s over the years and never really noticed much of a difference in hvac performance. This new one when the set temp is needs to be a few degrees lower also window fogging like I haven’t experienced since high school. When in auto mode the fan doesn’t blow hard enough to keep the windows from fogging when my 3 carpoolers are in the vehicle. It’s hard to explain but I drive 30k miles a year and have noticed sub par hvac system in this truck.
