"vent" setting very warm to hot
 

With my A/C off but the setting to "Cold" on the dial, the vent blows very warm. On "1" it's downright hot and on "4" it's very warm.

With the fan set to 0/off, the air blowing through from driving at highway speeds makes it very hot as well.

Basically, with the windows up I have to use the A/C or be cooked out of the car even though it's 70 degrees outside. With the windows down, it feels like you have an exhaust leak into the car.

What's everyone's else's experience? It seems broken to me, so I'm going to take it in for service.

My car also got a really bad knock today, but it went away. Very concerning.

I've noticed that its a bit warm too. Have tried changing the vent from recirculation to outside air?

I saw our member PekingDuck posted the same thing about warm vent so you are not the only one....being this is the very first production run/model, I anticipate issues but hopefully none major.

I have it set to outside air. I also turned the warm/cold dial several times hoping it would "unstick" something.

I'm thinking this is contributing to the fact that my A/C is terrible and can't keep up with an 87 degree sunny day.

I concur
 

It has not been warm around here but I've noticed that even when I have the dial at half way between coldest and neutral, the air is pretty warm. I haven't even bothered putting it into the heat section. Winter weather driving will perhaps be toasty.

Woo hoo! First model year problems. You can at least say that you're the first FRS/BRZ to be serviced, lol.

In all seriousness that sucks. There usually is an air door actuator that opens and closes a flap in your heater box to direct air flow. It could be that the flap isn't closing fully and you're getting warm air flow still. Ford owners can tell you its a common problem especially amongst trucks. Keep us posted!

I took too long to respond so my response was redundant...

If you press the recirc button does the air stop coming in?

It's weird that the A/C works, usually theres a motor or mechanism that will close off the vents or re route the vents in cases like this.

Has it been really hot where you live?

Either way, take it in just to to safe.

Are you still on your first tank of gas? I wouldn't be surprised if the dealer put regular gas in it.

If this is the only major problem, then I'll be happy. This is such a minor issue that I wouldn't even worry to much about buying the car. It's not going to stop me buying.

Maybe they have to issue a TSB or something to fix the problem. But I'm sure that it will get fixed if it does become a common issue.

It's not as bad as the first year Ford Fiesta's and their auto transmissions. A huge ton of people have problems with the Autos. They always complain about terrible shifts and the car jerking when changing gears. Or even the new Mustang. The cheap manual trannys in the new Mustang actually have been known to strip the teeth right off the gears.

Again, if this is the only issue we see from the FR-S/BRZ, I'll be happy and not really that concerned.

bneale

The dealer put in 93 octane, and this is my third tank of gas (I refill on 1/4 tank)

Will try that

Not really. It was 87 the other day, 70-ish today.

Wow, that should not be happening then...:(

I wonder if a factory reflash is in the works?

I have some other Toyotas that do the same thing, blow warm air on vent with heat all off. I think it has to do with where the vent air is aquired from outside. With set a recirc it will definitely get hot and steamy as you are just recirculating cabin air!

Well at least I could ride around with the windows down. Right now it gets uncomfortable feeling like the heater is blowing on you.

I'm experiencing this olin my toyoda rav4.. It's a year 97.. So guessin the temp control is broken or vent for heated air underhood is not closing fully.. Bring to service right away and let us know about it.

My 2004 Corolla S has always done this as well. Feels like the outside AC vents take a detour next to the radiator for some reason :).

Hopefully this isn't the case with the BRZ :iono:

BTW you guys should change the vent setting to hot and maybe it will do the opposite :iono:

Some cars are just that way, depending on how the underhood packaging, the exhaust pipe routing, and the HVAC ducting coincide with each other. My Miata's were always that way. The "vent" always issued warmer-than-ambient air, and having hot footwells was a very common pet peeve.

I've had a few cars that do this. It's probably due to the fact that the intake air has to pass firewall and then through the blower motor and all the plastic piping in the dash, so it has time to heat up.

My Eclipse does this. It's not hot but a little bit warmer than ambient. Even when off it blows some air in so you have to redirect it or shut the vents. But I always have my windows open when it's warm out anyway. Unless it's warm and raining, then I turn the A/C on.

I'm kind of surprised this car would do this though. I thought that was something they fixed/changed with newer models. I wonder if it has something to do with Denso's system.

Must be a Toyota thing...(My Corolla does this too)

Here's my solution:
Turn on A/C for awhile till the air is cold.
Then turn off the AC a little later. the air should start to cool down somewhat but will stay coldish.

I've always thought it had something to do with the ambient air temperature outside which its drawing the air from.

The worst part is sometimes i get a nasty smell with the dial on Cold until i turn on the AC which gets rid of it.

My Z used to do this but the heat would be coming from the floor.........after a few months it just stopped on it own.

My sister has a toyota camry 07 and it has the same problem since we first got it.. you could try before turning off the AC set the temp at a room temp(comfortable car temp) then turn it off. With camrys if you leave the dial on cold , and turn it off you will slowly feel the chill kick in.. Same goes with the dial on hot making your eyes dry out and a swamp in your seat

Also if it wasn't suggested already, check your oil, in regards to the knock.

With the AC off arent you just getting outside air blowing in with nothing cooling it?

This happened in my Maxima, as well.

I live in Texas and if the AC isn't on then you won't get cold air period. We can only use the fan with no AC in November.

Isn't there a nob or something to close the vents?

Try venting it to the windshield defrost setting.

The two center vents have shut-off switches so you don't get drafts.

The outer vents also close completely.

This should take care of it....just make sure you don't have the vent setting set to Floor just in case.

I tried something today that may help. I turned the AC on for about 5 minutes to cool the vents and then turned the AC off. The vents remained cool after that. Could be that letting it sit outside heats the vents.

This is so true...:sigh:

It seems that the cabin air intake is located above the firewall just outside of the hood but also on a location that's close to where engine heat exits. I noticed this too...
However with all cars equipped with standard AC it may well be part of very rigorous design exercise where minimal ducting is required to save weight. I know this may sound ridiculous by normal standards, but in my recent conversation with Mr.Tada, on my inquiry as to why seat recliner memory latch was omitted from the FT86, his response was that however convenient it was, added 2kg to the weight, and his goal was to reduce it by every gram possible.

So I just want to think positive. Also, if the engine bay is emitting heat well, and engine itself is dissipating it well. It also means that the overall, the engine will stay cooler on heavier track duties. Possibly even offsetting the consumption by ultra efficient AC system by keeping engine efficient, cool, and well advanced on timing of ignition.

Just food for thought, and one of many choices the designers made?

I remember with the First Gen Toyota Matrix the A/C didn't blow that cold on those hot and humid days and the A/C Line needed proper insulation which helped drastically.

Maybe look into that and get some foam piping insulation from Lowes.

One of the things I hate about Miatas.

We have a vehicle (non-Toyota) that blows cold AC while driving but when stopped, it's not nearly as effective. This is because of the small AC components used for weight savings and packaging. It took some getting used to (we inspected the equipment to be sure it was functioning properly) but now it's just a character traits of the car.

Perhaps you picked up a bad batch of Fuel? It happens more often than you think. Also you may want to try resetting your ECU, so that your Learning Trims default back to stock parameters. Hopefully everything is fine.

Hi all,
New here to the fr-s/BRZ forums. my daughter and i just bought a 2014 BRZ for her about 3 weeks ago.been reading, watching youtube videos,etc. on this new toy we bought. former owner had a problem with the A/C. beeing cold on driver side and hot on the pass. side. so i did a little researching and found it to be maybe the blender door. took this pic up underneath the dash, had to remove the glove box to see it (i also changed out the cabin filter). I cycled the controls and found that this actuator never moved ,so i assumed i did find it to be the blender door actuator and looking thru this old thread, it doesnt seem that anyone found the cure. Can i assume it just needs changed out/replaced?Thanks in advance

Did this a few years back...
