How do I stop the air conditioning from coming on automatically every time I start my car?
Jan 28
It is a 2009 Renault Megane Coupe.The Air Conditioning comes on automatically upon starting and remains on until the car has heated up. This appears to increase the fuel consumption, so I always turn it off.
I would rather if it didn’t come on in the first place.
Check to see on what setting the air direction control is set to, normally if you have it set to windscreen de-misting then the air-con will come on.

On most it will only come on automatically if you have left the climate control, if it has it in Auto Mode or if you have the air distribution set to blow air on the screen. Sad to see that you find pressing a little button such hard work to over-ride what is actually quite a useful function on most cars to quickly demist the screen.
Nothing you can do other than to undertake the arduous task of switching it off when not needed. If not set up like this you may have found trouble switching it on when the screen mists up soon after getting in the car. Such a hard life isn’t it?

I am surprised to hear that the airconditioner is coming on at all, but in particular UNTIL the car has warmed up. The car heating is provided with air that has been heated by waste heat from the engine cooling system. This does not require any extra fuel consumption, as it simply recycles waste heat.
There ought to be a switch that allows you to turn off the fan unit if you do not require it, and also a control that allows you to set a comfortable temperature.
IF the temperature control is turned BELOW the ambient temperature, then, rather than the heater, it will be the cooling system that is turned on, and that DOES cause the engine to use more fuel, as a refrigeration plant has fairly heavy power demand.
IS there not an "AC ON/OFF" control on the facia? That ought to stop the cooling plant from operating, but still allow the normal car heating to work, unless you also turn off the fan.
