Guys,

Just wondering if it was just my climate control or whether it was across the board, but it seems to have only two settings - bloody cold, or hot.

Without the A/C button on, the car seems to source air at about 24-25 degrees, even on a cool day.

With A/C on, the aircon constantly pumps in air at about 18c.

I take it the aircon gets contaminated from engine bay heat, and it's not programmed to "heat" air when the a/c is on an auto setting?

Additionally I have noticed that when I change modes from "face level" air vents to "face level" airvents and footwell airvents, the climate control does not activate the footwell vents. However, if I quickly cycle through all settings, (face/foot to foot, foot/screen, screen, face,face/foot) the foot vents then remain opened. Could someone with climate control please have a look if its the same case for them?

my climate control works but needs regassing. so its sorta takes ages 4 da air con to work. its just yours so far

Mine seems to work no probs man. Don't have the foot vent problems, and the temp seems to change noticeably.

I hear you with your complaints. Thats the one biggest thing that pisses me off about Mitsubishi's climate control is that when it is hot and you have the a/c going, you cant select face and feet at same time. You select it on the display manually but it still stays on the face. I know it sux but this is NORMAL and how it is meant to be and there is nothing wrong with your settings. In winter when you use the heater you can do face and feet but for some reason they dont let you do it when its hot.

As for the temp settings, i don't seem to have any probs. They do pump out as cold as they can until the desired temp is reached and then obviously the fan slows down then the a/c will cut out if not needed. The A/C and heater can work at the same time though. If you crank your temp up to say 28deg it will pump out heat but the a/c will still be running if you have it in full a/c mode being not a/c and eco.
Eco is there for those winter months when you only need a/c to come on every now and then to keep temp and humidity right. If you have it of just the * mode being full a/c then the a/c will be running nearly all the time. This is good in winter if you go to the snow or if your car is fogging up a lot. Gets rid of the humidity in the air therefor de-foging the car.

Additionally I have noticed that when I change modes from "face level" air vents to "face level" airvents and footwell airvents, the climate control does not activate the footwell vents. However, if I quickly cycle through all settings, (face/foot to foot, foot/screen, screen, face,face/foot) the foot vents then remain opened. Could someone with climate control please have a look if its the same case for them?


Mine does this.. other than that it works a treat.. :D

My climate control seems to have no vent issues, I think air comes from the foot well vents on bilevel. But damm it pumps some cold air out! We usually set it on eco at 25-26*and it still gets abit too cold.

HI,

I have a TH Solara (99) and it has none of the issues you describe. I can adjust the temp no worries and the controls to direct the airflow to feet, face ,window etc work fine. Mine has adustments between each phase that also work fine. I have no problems so far

l have a tj and actually had to have a solenoid or something replaced my prob was that it wouldnt allow air through the foot vents at all seems for it to change the solenoid activates the motor or something that then opens the vent your after .. ( l am not a mechanic and the amount of information they told me didnt make much sense )

I have 4 3rd gen Veradas and none of them will let you have air flowing to your face and feet at the same time in hot weather with the a/c on. Even when you manually tell it to do face and feet, it still doesnt do it and just blows on the face. I have had all of them back to mitsub when they were in their warranty periods and they say this is how it is ment to be. I think i can even recall it saying in the manual that it wont blow to face and feet in hot weather with ac on. It works in winter with the heating but not when cooling.

yeah its meant to be like that..

this is my understanding of how it works:

when you use air cond. you sould have it on recirculated air, not fresh air from outside...

when it is on recirculated air, it is sucking air into the system from the front footwell area, and then spitting it back out the top vents, those being the face vents. This is so that it "recirculates" the air in the way that it is intended to.

it differs in winter though with the heat on.. because we all know heat rises, you therefore use the foot outlets to release the hot air out of the system and it will rise up to the top of the cabin. It also helps to use recirculated air for this aswell because it is heating up the air, spitting it into the footwell areas and then sucking some of it back in to re-heat it.

Those with automatic climate control on their 3rd gens.. set the temp to 17°C on auto and see what the default settings are.. do the same with setting it to 32°..
when on 17° it should be face vents with recirculated air (not windscreen vents [there is a seperate function for that], nor feet vents, nor face/feet vents, nor windscreen/feet vents.) It works most efficiently with the default settings. Should also be on normal air cond mode, not eco mode.
when on 32° it should be on feet vents and recirculated air (not windscreen vents, nor face vents, nor face/feet vents, nor windscreen/feet vents.) It will heat the cabin more efficently if used at this setting (duh!).

now, as for bloody cold or bloody hot.. the temperature shown on the climate control screen (ranges from 17°C-32°C) shows what temperature you have set the "desired or wanted" cabin temperature. So, if you set the unit on 17°C and have it on auto mode, it will cool the cabin of the car until the inside gets down to 17°C (or up to if its like minus 5 outside). So if you set the temperature setting to 24°C and put it on auto, it will chose the mose efficeint and effective settings to get the temperature of the cabin to that set figure. (can heat it up or cool it down, depending on outside temperature) It isnt like normal air conditioning in other cars where you choose cold air, hot air or in-between-air. Its an automatic system, you are choosing the temperature of what you want your cabin to be, not the temperature of the air coming out of the vents.

I find that a comfortable setting is about 24.5°C.. and i have mine set on that day in, day out. (unless i have the sunroof open and window down, or it would be just pointless). During summer it will cool the car down (unless it has been parked in the sun all day, ill have it on 17°C for a good blast to initally cool the car down) and in winter it will warm it up. Once it gets to that temperature, the system easily maintains it, having the fan usually only on 1 or 2.

anyway, hope that sorta made sense.. its a bloody long post (didnt think id ever have to write an essay once i left school lol)

I've got climate control in our Camry, Mazda, and commodore, I know how they work! The constant issue I has is I could set the cabin temp on the climate control to 25c, it will still pump in freezing cold air with the ac on - and the cabin temp at this time feels more like 19c!

ohhh i see.. it would be handy if the unit told you the actual "current" temperature of the cabin aswell as the set temperature..

do you live in a very hot part of aust? becuase i know down here, if i set mine on 25 the fan speed is usually only about 1 or 2..

When on this setting is the air filtered before it is blasted out of the top vents? Or is it a matter of preventing having someone in my car with stinky toots on a hot day. If unavoidable I could perhaps request that they wash their feet before hopping in my car. :eh: I just don't want tootie odour blowing in my face...:disgusted

On another note, you could get one of these if you want to monitor your interior/exterior temperature and how efficient your air con is. Cool blue backlight too. :cool:

I'm with dave_au, the outlet air temperature has little corelation to the temperature setting. If the AC is on, it is freezing (term of speech, not actually cold enough to freeze water). The mid range temperature settings don't seem to operate as expected.

I've worked in process automation, but I can't figure out the "logic" applied to the HVAC system.

Ken

I'm only guessing here, but I get the feeling that the 3rd gen magnas may have a budget climate control system with only one or two sensors and fairly simple logic.

If the sensor is reading above the desired temp, the air con continues to pump out cold air, even though the overall cabin temperature may be OK. This may be the case if the sensor is located in view of a windscreen. The sensor may be heated up by the sun, yet the cabin as a whole may be cooler than the temperature of the sun hitting the sensor.

I don't know whether this is correct, since I've never seen the Magna setup, but it is plausible :D If anyone knows where the temp sensors are located in TL Magna's, please let us know.

there are 3 temp sensors in the TL, one on the top of the dash, one next to the stereo to the left of it with the little holes, and another sensor behind the front grille, battey side

My understanding was the cabin temp sensor was in that little vent grille thing next to the temp adjust dial.. :confused:

Car is getting it's (supposed) last warranty service in the next couple of weeks before the warranty expires at the end of the month, it's on the list for those guys to check out.

No problem with my TL climate control.

Hmmm... maybe one of the internal sensors is playing up? Remember, these sensors don't have to be super accurate, so car manufacturers use the cheapest sensors they can find :)

Good luck trying to convince the mechanics that something is wrong.
