Hi!

When I push "Auto" on the A/C I can only change the degrees, not where I want the air to blow. Why not? Is there some way possible to override this so I also can adjust where the air blows?

I also want to change so I also can just blow air at the front window, not whit pushing the "Defog" button, because it sets the fan to full, and A/C on..


Tommy!

AUTO stands for automatic. Once you set your desired temperature the system automatically does what it needs to to maintain that set temperature. If it needs to blow cool air out the top to do this it will. If it doesn't then it won't!

If you want to blow air where you want it then don't use AUTO. The button you want to keep pressing is MODE until the appropriate indicator lights up.

The ACC is really pretty smart. It choses air direction that will cool or warm the car in the least amount of time.

If you want cold, it blows air from the dash vents because cold air sinks. It blows it high, to let it fall. If it blew the cold air all in the floor, the floor would stay the coldest, while the top of the car would stay warmer. It gradually increases fan speed at startup to slowly blow out all the hot air that is in the vents before blowing the cooled air ful blast.

In the winter, the opposit happens. It blows the air from the floor to let it rise into the car. If it blew heat from the top of the car, the top would get really hot, while the bottom would stay cooler longer. It also waits for the air to warm up before it blows hard, this way it wont blast you with cold air.

The system operates as follows:

There are alot of different modes you could say the system works in, which i have listed below. the basic idea behind the AUTO funtions of the system is this:

Say it is 90 degrees outside. You want the air in the car to be cold. You could set the system to 76*. The system sees that you want the air to be colder, so it blows fully cooled air at the highest fan speed from the dash vents until the cabin starts to cool down, at which time it gradually slows the fan speed. When the temperature is finally reached (which it rarely is) the fan speed will be at the lowest or second lowest speed, and the system then begins to alternate between warm and cold air to hold the temperature at the set 76* and not to let it get warmer or colder than that. It will even alternate between dash vents and floor vents to keep the balance of air temp. The system operates similar in the winter.

Full-Auto:
Automatically adjusts fan speed
Automatically adjusts air direction
Automatiaclly adjusts air temperature blown

I understand this mode to be the same weather or not the AC is selected to be on or off. The system still behaves totally automatically, however the car may not cool down as fast inside if it is hot outside with the AC off, just like with any AC system. (if you press the AC button to turn off the AC compressor, the display will not light up the "AUTO" light because Mazda got stupid and didnt use the "ECO" light given to us on the display. This would have allowed the display to read "AC AUTO" or "ECO AUTO"depending on if the compressor was on or off.)

Simi-Auto 1:
Automatically adjusts fan speed
DOES NOT automatially adjust air direction
Automatically adjusts air temperature blown

Enter this mode by starting in full auto mode, and telling the system what you want the air direction to be. In this mode, the display will not light up the auto light because it isnt fully automatic. The system will remain in this mode untill you tell it to return to Full-Auto mode by pressing the auto button (which will reactivate the AC compressor if it was turned off), or by going into Full-Manual mode by adjusting the fan speed useing the fan speed knob.

Simi-Auto 2:
DOES NOT automatically adjust fan speed
Automatically adjusts air direction
Automatically adjusts air temperature blown

Enter this mode from Full-Auto mode by adjusting fan speed by useing the fan speed knob.

Full-Manual:
DOES NOT automatically adjust fan speed
DOES NOT automatiaclly adjust air direction
DOES NOT automatically adjust air temerature blown

Enter this mode from Full-Auto by adjusting the fan speed useing the fan speed knob (far left knob) and telling the system where you what you want the air direction to be. If you want totally cold air, adjust temp to 60. If you want totally hot air, adjust the temp to 90. If you want air of any temp in between, adjust it to that number. The system will do nothing to see to it that the car reaches this temperature. all the in-car thermostats are disabled. For example, if you select 60, the car will constantly blow air that is apprx. 60*. If you select 72, the system will constantly blow air that is approximately 72*.

My Mazda6 (european 2004) uses ECO light for the A/C economy mode. The A/C compressor has 2 modes, standard and economy. In economy mode the temperature of the blowing cold air is about 6 degrees Celsius.

No way I know of to see the "ambient" temp inside the car. only can see what temp the A/C is set to.
