Top slider is for temperature Max Cold = left end. Max Heat = right end.

Bottom slider is for on/off + airflow selector

Off = off (!)

rectangle = console & door vents only

down arrow = console & door vents + footwell

up/down arrows = means console & door vents + footwell + windshield

up arrow = means console & door vents + windshield

The door and console vents are also individually manually controllable

The final right most position is the windshield defogger, it gets you maximuum fan speed, maximum heating with AC on and windshield vents (manually close the door & console vents for maximum defogging). For defrosting don't use this - turn AC off and use max blower and max heat instead.

Fan speed knob is just for fan speed 0 = slow (not off) through 4 = high

To get AC on press the AC button, select an airflow slider setting other than Off.

The temperature setting is an absolute value not just variable - e.g. you should get exactly the temp you program (once temps stabilize) - regardless of external temperature. You have internal and external sensors to create a feedback loop to do this... however they must be working properly or you will only get max heating and max cooling...

Get the owners manual for you car then you will know - if you don't know this there are many more things you don't know too.
