Air conditioning
Got asked to do an air conditioning diag. Hmmmmm
Discussion
Inspected to verify 270 A/C operating as designed.
Advised customer proper operation of system is to roll both front windows down at 70 mph.
I'm assuming this particular vehicle did not come with such a luxury? Not seeing an explicit A/C button/switch.
It’s the blank in the bank of 3, would be to the right of the recirculation button.
Well there’s your problem. It’s missing the a/c button. Easy peasy.
Gotcha, thanks!
Google tells me this is a Honda...Jazz? Known as a Fit here, but I guess I've never seen this dash much less heard the other name.
Yeah it's a Jazz. Right hand drive so probably not the Fit (US Version).
The AC should indeed be where that blank button is on the row of 3.
The Fit looks just like this (mostly)
No AC but heated mirrors? Damn
Heated mirrors are dirt cheap in comparison to an AC system. So are power windows and even a sunroof
Heated mirrors have been in most cars made this century. If you had them, they'd come on with the rear defroster, it's just that only recently manufacturers started making it more obvious
Such confidence
what is this, a dacia sandero? /s
Good news!!!!! No sorry it’s a Honda jazz.
hmm, so they finally jazzed it up!
AIR CONDITIONERS DO NOT WORK THAT WAY, GOODNIGHT!
How's the family, Morbo?
BELLIGERENT AND NUMEROUS!
Other hand drive Honda Fit
Windows down for AC 360
I don’t get it
The car doesn't have air conditioning
Then why do I see 3 dials, 2 vents and a button all relating to air conditioning?
you don't, those are to blow air on you and make you wish you had ac
Those are for the fan. Where’s the A/C button?
I’m not seeing any buttons related to air conditioning
Ventilation ≠ air conditioning.
Why does the dial have blue and red bars? I’m very confused
Is that a genuine question or are you trolling? The red side is for hot air using engine heat, the blue is for air that has not been heated. Neither are for air conditioning.
Genuine question. I’ve never seen a car without air conditioning in my life, other than something like my 1978 Holden Kingswood. I assumed every car from the mid 90s had aircon standard because I’ve never seen one without
Oh! Yeah, up until very recently it wasn't uncommon for base-mid trim models to have optional A/C. It was an easy way to save $1k or so on a new car. More if it was lumped into an option package.
Turns out the last vehicle with non-standard A/C was the 2022 Jeep Wrangler, so as of then all(?) new vehicles have A/C (In North America).
I'm afraid the headlight fluid leaked all over the turboencabulator and that part is out of production.
FYI O'Rileys has headlight fluid at the register. It's a gel that covers the bulb for waterproofing if your taillight is busted.
They also have Elbow Grease which is like a mix of gojo and comet.
I've now defaulted to sending people to get "striped paint"
Bad news friend, they could succeed. https://www.ppg.com/en-US/traffic/products/preformed-thermoplastic
In the usa the ac button was on the bottom selector knob.
The steering wheel is on the right side. So in which country is the vehicle located or made for?
Wait did someone actually order an Irish spec car with no AC? Because I think there, they also tax you on the accessories on top of engine capacity and on road weight.
I don't want the AC on when it's freezing outside to defrost the windshield when I can use the heat! DUH
RHD cars fuck me up because my brain is like “okay obviously this is some mirror world car, so I’ll just reverse everything” but then it’s all just normal controls in the normal direction
I think its....blown...
I'll show myself out...
They need to put the window down farther & drive faster & it will work👍🏿
What I learned from this post is that no one is familiar with a psychometric chart, much less how a dehumidifier works.
Good ole Honda fit in some northern place
Three separate control knobs in shit locations forcing driver to lean over and possibly take eyes off the road to adjust while driving. Ergonomics engineer D+ graduate.
Why are the locations bad. You can touch them with your left hand without leaning over.
The assumption seems to have been that the driver sits on the left in this car, which is a tad silly as you cannot see the pedals on floor on that side.
It’s a right hand drive car 😆
I really hadn’t thought about it bc it’s likely I’ll never drive one, but what a freaking nightmare to get used to left handing the controls lol.
The gas and brake and ignition all stay in the same places, but you’ll definitely hit the wipers instead of the turn signals multiple times and left hand shifting with 1st gear farthest away in a stick shift is funny 😂
The really annoying thing about right hand drive is that which side the wipers and signals are on isn't even consistent. UK cars the signals are still on the left like they are in a left hand drive car but the JDM stuff flips it and puts the signals on the right. So you can't even make up some kind of rule of thumb like "turn signal stalk points towards the outside of the car" because that's not true for all RHD cars.
Omg I hadn’t even considered the shifter. Most US people don’t drive manuals. You have to special order it if you want to purchase a new car that is manual lol.
If you lived in a country with RHD cars it would the the norm to you and you wouldn’t be getting used to it it would just be how it is and how everyone does it lol.
You don’t know if a fabulous life in Europe awaits me 🤣
Most countries in Europe are LHD I’m pretty sure it’s just the UK and Ireland that aren’t lmao.
Now how in the hell would you know that?
Oh. It's the phone holder facing toward the right side of the car, isn't it.
Damn. Missed that at first.
I also just know the interior layouts of most every common car out there from work 😆 this is like a 2008ish Honda Fit and I know all those knobs + hazard switch are on the left when they’re left hand drive
LOL, well carry-on with your exotic RHD car diag then sirs!
p.s. 3 separate controls still sucks.
As opposed to what? How do you control temperature, fan speed, and vent selection on fewer than 3 knobs?
A combo button/knob; one for fan speed/vent selection control and one AC on/off-temperature control.
So fan speed would just be on or off? No varying speeds?
The knob button selects vent mode and rotary dial controls fan speed.
You’ve lost me. A knob button and rotary dial?
Damn man, sub won't let me post picture. The center knob is pushed which cycles thru the vent mode (changes the vent icon in use) while the outer rotary ring adjusts fan speed.
Sorry for my basic explanation and I'm NOT trying to down on your know-how.
It’s better than all touch screen bullshit at least, you know where the knobs are naturally and you can grab them without splitting focus
True that, I still occasionally drive my 92 Mazda Protege with lever temperature/fan speed/vent controls that still work.
Blast from the past 😂 are all the vents and doors vacuum operated? Threw me back to my 88 foxbody with that one, but obviously the shit in the foxbody barely worked at all
Judging by the knob location and phone mount, gonna say this is a RHD vehicle...
Possibly right side drive..?
I’m more impressed they managed to find the one semi-modern car without AC but somehow has heated mirrors…
Heated mirrors are way more important than an AC in some parts of the world...
When the cold creeps in, or just the heavy condensation in a tunnel hits the wing mirrors you'll be very happy for this.
I live in Norway. Honestly, an AC is only really needed at most one week in the summer...
A/C runs with the defroster in order to dry the air. Does defrost even work properly with no A/C system?
Yes, using heat. And usually when you use the defroster you have your heater on anyways.
Melts the ice, sure - but what about the foggy windshield?
Have you ever had a foggy bathroom mirror and de-fogged it with your blow dryer? Like that. The heat dissipates the fog. How do you think people did it before they had air conditioning?
c'mon this is reddit, cars have always had A/C, just like there's always been the internet and nobody every went to libraries to looks stuff up.
That’s because the heat is also dealing with the humidity. That’s not what’s happening in an enclosed vehicle
Doesn’t it? In my fiesta without air conditioning it works just fine in winter. It has for the past 32 years. It has for other cars without AC for literal decades. Of course it is better with AC, for example when the windshield fogs up due to rain and you don’t want your heater on full blast. And, of course, for it to work will take some minutes because the heater will need to warm up whereas the AC can defog pretty much instantly. But it works just fine nonetheless with just the heater and nothing else.
I remember my dad’s W210 E class used heat for the windshield defrost regardless of set or ambient temp. Worked a treat every time.
Maybe part of it is related to the vehicles in areas that need A/C also have humid summers.
That may be. Because I was thinking of the defogging on cold winter mornings, not humid summer days.
When you increase the air temperature, you increase its capacity to hold water. That’s why it’s more humid in the summer than in the winter. Most of the time, foggy windows are during the winter when the air is much drier anyway, you can just switch to outside air and it’s essentially already air conditioned.
AC certainly helps, but all you have to do is increase the air temperature and it can hold more water. In most cases that works fine.
Yes everyone before ac could never see out their windows... What a well read historian we have in our midst in these times. Praise be gents! Luck is on our side today! Buy a lotto ticket for we are already rich with knowledge and now we are on to worrying about wealth!
Brilliant rebuttal. What did they do before heaters and defrosters? Surely they all died!
Putz.
Considering the model A had heaters in 1929.... They road horses.
Heating the air lowers the relative humidity.
All you have to do is raise the surface temp above the dew point.
Running the A/C will reduce the humidity in the air (while cooling it) but using heat will keep the humidity from ever condensing on the windshield.
You know that air has to be able to get out of the "enclosed" vehicle right? If it couldn't you'd either asphyxiate from lack of oxygen or the windows would blow out when you put on the blower...
If a modern vehicles defroster and airflow alone are adequate, why do they always advise people to use the ac in conjunction with defrost?
Holy shit are you guys slow or?
I think you don't realize that there are places other than where you live. There are places in the world where AC is not always required.
In the depths of winter the AC only works a little anyway because the evaporator will freeze.
You raise the temperature of the air, it carries more moisture and gets taken out through the ventilation system.
This obviously doesn't work well in a place where its hot but it works just fine where\when its cold. I didn't have a vehicle with AC until I was 25...
Edited for clarity
Warm air traps more moisture than cold air.
Do you know how an A/C works? They remove moisture from air.
So why is there fog on the windshield? The glass is colder than the air inside the car. That causes the air near the glass to get colder and "lose" the moisture, which condensates.
So you can attack two problems to solve it:
If you don't have A/C, you only get (2). You have to blast the glass with hot air until it warms up enough to stop fogging. I imagine in very cold climates you don't really stop using the heat so it stays defogged even though your air keeps moisture. (Also very cold climates are rarely humid so they start with less moisture.)
If you do have A/C you can do a little dance. A lot of times cars will ignore your heat setting and blow cold air anyway just so the A/C can act like a dehumidifier. But if you dehumidify for a while THEN switch to heat, you tackle both problems. "Cold" in a lot of climates isn't so stupendously cold the glass needs constant heat to avoid fogging again. But I've been in conditions where I was constantly balancing comfort vs. visibility because things were just right to make it so the moment I switched to heat condensation would form again.
Yes, by using the other side of the same equation. An air conditioner forces air through a cold heat exchanger causing moisture to condense on it, because cold air is unable “hold on to” the moisture. This makes the air dry.
Now if you want to evaporate moisture off a surface, you blow hot air over it, which is more easily able to carry that moisture away from it than cold air would.
This is actually why many modern air conditioners in cars first cool the air to dry it and then heat it up again to be able to trap more moisture when running the defroster.
I feel like we obviously live in very different climates. Anyway, if they work without A/C then I believe you. They don't work very well here without it.
By the time you heat 80%rh 2°c outside air to 20°c in the car it goes down to just 24%rh, more than dry enough.
Yeah it does, used to have an 89 Comanche that had no AC, but had a very solid defroster.
You heat the air, it holds more moisture and blow that air on the windshield.
Yes, it's not as efficient because a proper defrost will run the air over the A/C coils to remove humidity and then heat it up to be more efficient.
But what you can do is run the defrost/heat on the windshield and crack your windows. You'll keep the heated air and then displace some outside, this removing moisture.
It works but not as well.
Laughs in GenX
You kidding? I live in sweden, i use ac april>october atleast.
How hot slash cold does it get in your part of Norway?
Here in Calgary Canada we get about 3 or 4 weeks of plus and minus 30 sprinkled throughout the year. I'm definitely thankful for AC in the winter.
My peugeot 106 (1998) had heated mirrors but no ac
I don’t mean to be mean, but 98 was 27 years ago, not exactly a modern car anymore.
