The 06/07/08 civic heater controls are at the bottom-center of the dash, in the spot traditionally occupied by a radio. the left knob controls temperature, and the right controls fan speed. This as I recollect is the reverse of the usual. Getting the settings as you want them requires multiple prolonged glances away from the road, and a bit of thought: pushing buttons and reading the result on the lcd display. If you switch the thing completely off, and then back on, there's a fair amount of resetting needed if you had it on anything other than full "auto". One of my favourite tricks is to try to turn down the radio and find I'm turning down the temperature.
I know a lot of this is gripe, but considering small, incremental bits of inattention and confusion can have major consequences, I think Honda could have done better. Any other current model civic owners care to comment?
