I find that it makes the most difference in Frigid weather - teens Fahrenheit or lower. When the outside air isn't vastly colder than the cabin air, the difference is mainly in the reduction of exhaust fumes sucked in while in traffic.

I've concluded that for Seattle conditions (low 40s and steady rain) the magic setting is: full recirc., face and feet vents, heat and AC lights on, temp at mid-60s. Fogging was driving me crazy over the last rainy week using various combinations of fresh air and windshield, heat only (AC light off) or feet/windshield vents, or the mystery mode and feet only. Finally tried full recirc. with AC on yesterday and cleared the windows well without too much power consumption shown on the displays.

Yes, Recirculate with heat and A/C is best for defogging. I try to avoid it because it uses the most power, with both the heatpump and resistance heater running, but it's very effective, and lets you leave the car "closed" to most exhaust fumes. The car won't let you use Recirc with the defrost modes, but floor only, with fan on 2 or higher, works fine.

In winter 0F to 20F I regularly drive around in the partial re-circ and often I have to switch to outside air to keep the side windows from fogging/frosting up. As soon as I start to see it condensing and moving a bit forward I switch to no recirc and it clears back up, then after a bit I switch it back into partial recirc to reduce heat load. In the spring and fall (25F to 50F) it is similar except I use full recirc and then switch to partial recirc if it starts to fog up for a bit.

What fan speed(s) are you using? The higher the speed, the less fogging, but the more power used.

I rarely run above 1 or the slowest speed and heat set to 72F. I should say for the first two winters I rarely ran the heat unless I had passengers, now I just leave it like this to take the edge off and keep the windows clear. It is amazing how much even a little heat can make you feel more comfortable. My wife however just sets the heat to 80 with all outside air and makes it worm :) In winter when it's 0F outside and I have 4 kids on the way home from swim practice with wet hair and swim bags I am forced to run defrost in 3 or 4 to keep the windshield from freezing over with all the humidity inside, the back windows still frost over but the kids like to draw on the ice :)

Others have found that with the fan on 1 you can set the temp as high as you like - it doesn't matter. I use speeds 2 and 3 usually, with partial recirc and floor only vent. I usually, have the temp set to 75-78.

Yes, when it's below 30F outside it doesn't matter what temp you set it to, if it is set to 70 or 80 it draws about 1000w once it's "warm" and it will never hit 70F inside on fan speed one anyway :)
