disable auto a/c
 

Does anyone know how to set it so that that air conditioner does not automatically come on whenever you turn your air on. When I had my RSX there was a little trick that you had to do by holding certain buttons when you turned the car to on so then it never came on automatically again. I was wondering if anyone knows if there is a way to do it. It's annoying and I am thinking there is some way of disabling it.

I agree, its annoying but i just press the a/c button off and am done with it...

I asked my dealer about this and was told that when climate control is on auto, the AC light is on indicating AC is ready. It's not being used unless the temp setpoint you pick requires it. Not sure if that's true but it seems odd as it makes it look like the AC is always on. I just set the desired temp and forget it.
Seems to work.

No, you can hear the compressor and you lose like 25 hp. When the light is on, it is definitely on.

25HP? If you are in a Chevy Cruze maybe

It's probably more then 25. I'm not sure about your comment about a cruze.

I was always led to believe the A/C costs like maybe 5 hp.

I don't think I'm u set standing what the problem is... I always just turn my A/C on or off if I want it. It never just comes on by itself for me...?

I know it's more than that. If you even change where the air is distributed it will pop on again. You also don't have full control of circulate or fresh air. It will force you to have fresh air on most settings. The air filters aren't good enough and you can smell outside air so I wish I could control that also. It's the worst thing about this car.

I agree, it is quite annoying. Mine will stay on "recycle" if i push the button but anytime I change the temp or whatever, it goes back to fresh air and i have to push the button again...

Even your entire home AC system doesn't require 18.5 kilowatts (25 HP).

The power draw isn't anywhere even close to 25 HP.

How do you figure you can use that number to a motor vehicle? I will bet that it is very close to 25hp if not more if you put your car on a dyno. That is the only way to tell. I'd love to see a graph with it off and on. The fact that your rpms jump up 250rpms while idling is a good sign it is greatly effecting your engine efficiency.

You wont see jackshit on the dyno because the AC shuts off when you go wot. 3HP can run a 4 ton compressor.

Because you can. Power is power is power is power. Doesn't matter in the slightest what units you measure it with.

Also keep in mind that the AC will disengage when you hit WOT. Really step on the gas and feel the vents... the air gets almost instantly warmer for a minute.

Otherwise as others suggested take it off auto... I tend to think it is not always engaged because even when heat comes from the vents the AC light never goes off.

Also no way you are losing 25 hp...

I too would like to be able to set my vent to recirculate without having to run the A/C, which our cars do not allow.
