Weak A/C blower???

You sound mad friend. And you're very misinformed or can't read, because this section of the forum is full of people who can't afford/get a 22, coming in to complain about something they don't own because they are personally offended about a v6 or a chrome grill.

 

I bet a vast majority of 2022 owners don't regret it for a second. I don't.

 

I also noticed that the AC didn't seem to blow hard until you lower the temp to Lo. Not that it matters much, if it is hot enough that I want the air to blow hard, I'd likely have it set to Lo anyway.
I have also found that the ventilated seats are somewhat lacking. I used to have a Lincoln MKZ, and the ventilated seats in that felt like I just spilled a cold drink in my lap. It was nice. These work fine, and have been especially great for the last couple weeks in the 90+ temps, but you'd think they would be more noticeable based on how loud they are. If the passenger ventilated seat is on without anybody sitting in the chair, it is super audible, but I can't really hear the driver seat with the radio on at all. I guess I just have to turn the AC seat off for the passenger side when the wife forgets.

It also took me a bit of tinkering to figure out I needed to turn off the auto climate feature. I couldn't ever tell if the AC was actually on when that was enabled.

 

**UPDATE**
Took the truck to Toyota today to get all the recalls taken care of. While there they did an ECU flash they didn’t advertise or prompt you to get done on the app, like the other recalls. I’m assuming they’re just going to flash everyone’s ECU wether you bring it in for service or for the recalls. Anyways.. the AC blows harder now, and doesn’t drop pressure when you bump it up from “Lo” to 60 and so on. It’s stays constant all the way to 70 then drops down some, but most vehicles drop pressure when you get to the heating range. I haven’t noticed any other changes from the ECU flash yet, but that one was for sure noticeable. I’ve circled what I think was the work they did that corrected this. Shifts weren’t bad to begin with, but seem smoother now..? But this could absolutely be a placebo effect.
Just thought I’d let y’all know about this. The A/C was a huge issue to me. Glad they got that fixed.

 

I'm sure y'all are aware but in my SR5 TRDOR if I drive in "ECO" the A/C is considerably weaker per setting level then if in normal or sport. 102 here today, kept it in normal all day and worked just fine.

 

ECO mode is an ECO AC setting. That’s why it’s weaker. And an Engine ECU update shouldn’t have an affect on how the AC blows. The AC has its own control unit separate from the engine ECU.

 

I wasn’t referring to eco mode or anything like he was above. The my and others a/c was weak as hell in any mode. Sport, normal etc. the ecu flash most definitely took care of this issue. 100%

 

I doubt that… there’s no way an engine ECU update will affect the AC. Maybe your dealer found the refrigerant low and refilled it. I’ve seen a lot of people on here complaining about weak or hot AC and the refrigerant low from the factory.

 

It was always plenty cold. It didn’t blow hard enough. Now somehow it does. Absolutely undoubtedly blowing harder through all temps. Maybe they flashed this a/c ecu too. Idk

 

So I own a 2022 Toyota Tundra iForceMax, and I live in Arizona. So it gets hot, I noticed the same thing with my AC, it wasnt blowing hard, and not getting that cold. I was going to take it to the dealer, but I found out, when you start your truck. It automatically turns off the rear seat cooling. Once you turn it off, it blows alot harder, and colder. I also use the air recirculation

 

Are you running on eco mode? What I was told was- If you’re on eco mode the ac also works on it.

 

To get the most out of the a/c system is to run it on Lo setting and fan on high. It will cool better when set to the Lo setting but the a/c in the Tundra is not a benchmark system and way below what Ford does with their a/c max setting.

 

Taking a closer look, I think a lot of the blower system problems is the ducting. The vents "look" big, but if you look closer, the opening of the ducting is quite a bit smaller than the vent itself. I've had many Toyotas over the years. And have had the dashes partially disassembled for installing stuff. They used to have formed duct work as big as the vent itself. This 3rd Gen looks like they used a 1-1/4" vac hose stuck to the back of a 4" vent. Also by not having the vent louvers adjustable, even though you angle the vent, the exit straightens it back out. So it doesn't blow where you want it to. When you turn the blower up or full blast, it sounds like there's an air leak inside the dash. You can hear it but the output doesn't match the sound

 

My AC works great. I'm coming from a 2021 F-150 and it had a really good AC, but I'd put my new Tundra's unit right there with it. I live in AR and we have had some 115 heat index temps over the last month and I typically never have it set higher than 2 bars once the cab has fully cooled down.

 

go in with carista and change temp dial calibration to -2, it fixes it works great

 

23 Platinum in CA here. This whole week has been 90-100 degrees and the highest fan setting I use is 3. Of course when I first enter the truck, I blast it all the way to cool it, but I always end up at a driving level 2 or 3. Wife is comfortable with those settings too. Keep in mind, your fitness will affect your comfort level too.

 

Shots fired!

 

ya, since I'm over weight and get the meat sweats after the Ol' 96er, I'm supposed to not want my AC to work as well, HA.

change to -2 temp dial and not worry no matter what shape your in, remember, round is a shape, HEHE

 

Same issue in 2023 limited, blows hard in rear. No or minimal blow felt in front vents in every configuration. (for heat)

This is a new purchase in winter, can’t comment on summer a/c yet

is the carista trick a solution?

 

I've read from some others here and was told by my service center that the weak airflow is normal and its supposed to be like this. I don't buy that. If it's supposed to be like that why does it give you the option to increase the flow if it isn't going to? Also how does that explain that the rear vents will still blast air as you increase the fas power. Why do the people in the rear have to have their faces blown off for me to get almost unnoticeable increase in flow? I think it's sad that people are making excuses for Toyota and that the service centers are trying to tell people it's just like that.

This is like the iPhone reception issue when their explanation to customers was, "you're holding it wrong"

 

Biggest BS answer coming from someone who doesn’t want to address the problem. Same as the alignment issue. Taking in my 2023 tundra for 10k mile service tomorrow and mentioning the AC issue. For winter time this is unacceptable. Barely blows any air at all. Cheapest Toyota model they have works probably better than these over priced trucks

 

I just put mine on auto and let it go, even in the stupid hot North Carolina summer I had no issue

 

If you don’t have an issue with it that’s great. However there’s a large number of people that do. Even with the Carista mod not getting the flow of air that should be coming out. So consider yourself lucky that your truck has a functioning ac/heater. However for the rest of us this is unacceptable

 

I don't have too big of an issue with the temperature as I keep mine in Low in the summer. It's the lack of air flow and how loud it is at higher settings but weak output.

 

that’s the same issue. Most of us are having at least those with this particular issue. I dropped off my truck at the dealership today for 10k service and mentioned the issue to service rep who was servicing me. The service rep said that’s normal…….. so a $55+ thousand dollar truck barely producing any airflow out of the vents is normal comparing to a under $20K Corolla that has tornado coming out of its vents?
I also mentioned that my steering wheel is turned about 15° to the right, even though the truck drives straight and the alignment was recently done at Toyota, which he proceeded that’s also normal steering wheel cannot be taken off and adjusted due to having electric power steering. That’s when I realize this guy is a complete idiot, and there’s no point in continuing the conversation. I left the truck at the dealership and got a loaner. Meanwhile, if they don’t fix it, I’ll have to contact corporate because this is ridiculous.

 

Oh I know it can be taken off and adjusted. I even wanted to get a trd leather one off eBay and see if I can switch it with mines. Good call on speaking to someone with knowledge instead of the key/paper work handler.

 

My AC works fine- very cold indeed- no complaints.

 

All Toyota tundras (all gens) have similar flow issues. The consensus for maximum flow is to engage the "auto" feature and set temp to "lo" for cold and "hi" for heat. Only adjust to a specific temp after the auto starts to drop the fan speed. It's a Japanese vehicle efficiency thing and all based on the system doing the least amount of work to achieve the desired or set temp. In Auto, the system is forced into "maximum power flow" state which is actually higher than the fan speed being set to max. If the fan is set to max but not in Auto, the efficiency part of system is still in play and will still somewhat limit the output because it will still achieve the desired temp but not like it's in a hurry. Only with the Auto selection on with Hi or Lo temp will engage the true maximum airflow because it bypasses the normal operating efficiency settings.
This is not just a 3rd gen issue. It's a Japanese efficiency thing that is seemingly handicapped compared to any domestic a
HVAC system. I can make icecubes in my f450 cupholder with the AC barely on... American Gold.

 

Thanks. I know mine is more efficient in Auto, just didnt know why,

Also turn off that ECO crap off

 

Why would Toyotas engineer approve this? Owned Highlander, sienna, rav4, and Corolla none of them had this idiocracy
