I had tried to turn the temp. knod to 10~11 oclock position, notice that the fc have improved ,but its a bit warm especially in the afternoon lo. will monitor the fc again on the next tank By the way never use the 'max a/c' before, is it temp will auto set to the coldess???if it is set to max a/c means that compressor would'nt cut off n keep on all the way During noon time turn ur centre knob to "max a/c" and 1 step down for temp range. It'll helps to cool down faster. Try to wind down ur window for a few min when moving off, it'll helps to dissipate hot air faster.

Our a/c is abit funny type. It'll mix with the hot air as to achieve the temperature u'd set. The max a/c is to bypass tis function as it only pump in cool air fr compressor.

that means the compressor is not going to cut even it is cold enough when turn to max a/c?

It'll cut off as long as the temperature reached the setting u'd set.

If i don turn to 'max a/c' but turn the temp. to d extreme blue side d compressor will cut off too. so i was :Thinking:wat is the uses of d 'max a/c' is it colder?

Its been set to a low temp of say 9-10deg and will maintain that temp. The mechanical flaps will control the flow of hot air from the heater to attain th temp you "set". For my old Spectra, I removed the heater (thinking it will save fuel!) and the aircon was measured by my thermometer to be 10deg at the outlet vent all the way. At night, I can feel the compressor cut off and on again to maintan that temp. Following that, I too paiseh to go back to C&C to reconnect the heater, so I went to an aircon guy to install a real thermostat. After that the aircon cuts off according to my set temp instead.

Heater can be removed? so does it really improved in your fc after removing of your a.con heater

Not removed. Just disconnected. No improvement in FC! Bro. u disconnected d heater from the engine bay No idea...I asked C&C to do it for me during 1K servicing. ;D Whatever they did, after I got back my car, the aircon was super duper cold no mattter what setting I turn to! That's why after 2 days I sent it to an aircon guy to install a thermostat.

bro. sure that C&C can do it for us . 1more question, even if the temp. set to the max it will still mix with the hot air

If u take out the heater, it'll give u max a/c with the coolest setting all the time. Ur a/c piping might frozen. So if u decided to take off the heater, suggest u install an aft market thermostat like wat bro airconvent did.

So if u decided to take off the heater, suggest u install an aft market thermostat like wat bro airconvent did. Don't worry, that should not happen. As far as I can see, the compressor cuts off at around 6-8 degC so that's the temp of the air without heater. Icing is a phenomenon that occurs mostly on standalone aircon units as far as I can determine. BTW, you can do experiment. Set your aircon to 1 marker above hot and off the aircon (not the fan, but the a/c switch). You will see the air turning warm. That's the amount of hot air at that setting. hence if you off aircon switch during driving, make sure the "cold" setting is set to max as that will literally close off the heater air flow.

cool! btw, the moral of the story is its pointless to remove the heater because the aircon just gets too cold. So if you want colder, just set to colder setting. Its a waste of money to remove the heater and then install a thermostat. There is no guarantee the thermostat will fit properly. The one on my spectra was too short, so the guy had to do some fabricating of an extension to the spindle which weakened it. Luckily for my Spectra I mostly left it at one setting which is usually the least cool one because I do not like too cold...heh heh

:goodnews:temp. set to 10~11oclock position do helps at the fc, last tank i get 518+km but this tank after i set the temp as mention my fc increase by around 11km. Noted: no change in driving pattern

my aircon used to be quite cold when on 1, but recently not very cold liao....anyone know whether we need to top up e gas or what? being driving for 3 yrs plus liao....last rd go CAS svcing, they ask me whether wan consider change compressor...$600+..wah lao...but don't think so serious as on higher still cold after a while... anyone can advice?

As gas leaks and is replaced by air, it mixes to form a corrosive material which eats up your condenser. Hence not good to let the aircon gas level drop. I suggest you try to top up gas first for low cost solution. If can afford it, do a chemical wash of your condenser. cheers
