Just updating that my Air Con has been fixed and the fuel consumption is a much more satisfying 10L/100km when driving with Air con.  I can get around 540Km from a full tank and a full loaded car before the fuel light comes up.

The previous owner had overfilled refrigerant into the Air Con system which made the system too hot, resulting in the radiator fans constantly running on high on hot days.  So my mechanic had all the refrigerant taken out and then refilled with the proper amount.  Now when the Air Con is on, the radiator fans run briefly on a loud high speed before settling down to a quiet low speed which is so quiet you don't even realise the air con is on apart from a slight load on the engine.

It is true though that these new air con systems with variable displacement compressors don't cycle on and off as much as the older compressors.  They adjust to light compression once the air con system drops to the right temperature when cruising.  So the radiator fan does constantly run on hot days but should only run on quiet low speed when cruising and switch to loud high speed intermittently when stopped at traffic lights.

Those who are getting excessively poor fuel consumption with their Toyotas should test whether the air conditioning system is the cause.  Compare the fuel consumption between air con and no air con.

Hi philpreston3072, just wondering where did you get the air con repaired from? I have having troubles with my air con and looking for a good mechanic. Thanks

So I took it to an air con guy who said that gas level is ok and suspects some issue with the signal or a component of the compressor that receives the signal and turns it on.

Hi fellow,

I have a Tarago 2006 which I bought 2 years ago from a dealer. One sunny day when I turned on the air con, it made a strange hissing sound and then stopped blowing cold air. When I turn on the a/c, the car can sense it, the condenser fan turns on, the vent blowers work but the compressor clutch does not engage. I called a mechanic who said that some cars have a sensor that stops the clutch to engage if the gas is low. 

Thoughts?

Thanks
