If your 09 A/C works anything like my 03, you have to turn the temperature knob down all the way to low (when in auto mode), if you want the fan to blow at high. If you leave the temperature set at 70, it will get there, but it's not in a big hurry. Just turning the temperature down to say 65, will increase the fan speed enough for me most of the time.

I began having this exact problem AFTER my old battery failed on my '99 Accord. When I took out the old battery, there was a ton of battery acid buildup on the (+) terminal. I replaced it with the strongest battery I could find, and immediately started having the flashing climate control, and no lights on the gauge selector display.
 
After tolerating the inconvenience for several months, I finally decided to get some plumber's sand paper last week and clean up the battery terminals AND the clamps on the wires which connect to the battery to get them shiny again. Then I reconnected the battery, and so far everything seems to be working great.

For those interested, an old toothbrush dipped in a paste cosistency mix of baking soda & water will clean a battery terminal or clamp beautifully and cheaply.

As the title suggests thanks for responding. I was constantly in a state of OMG what is wrong because I kept getting the impression that these were normal commuting numbers for everybody. My car consistantly gets 27 and I thought there was something strange. Guess not.
 
Although with winter approaching and the defrosters going I expect the numbers to go down, especially since when the defrosters are on not only is it taking heat off the engine, which I've heard is bad for mileage, but also the A/C is on and running the compressor, which I've heard mixed responses on.
 
So again thanks.

tankbeans,
 
Dudley posted this earlier, and I assume he'd be okay with me pasting it on here. If you'd like to use the defroster WITHOUT running the A/C (as when just de-icing the windshield), here are the steps to allow you manual control of the A/C when the defrost choice is selected. Stock, you cannot manually turn off the A/C when the vents are set on defrost. The compressor will keep running, even though the light turns off. Using this "hack," YOU control the A/C.

1) With vehicle on, push the airflow button for "top vent".
2) Shut car off.
3) Turn temp knob to the coldest setting
4) Turn fan off
5) How down both "Air Recirculation" button and "AC" button. With both buttons depressed, turn key to "ON" position. (don't need to actually start the car) Keep holding the buttons down for at least 7 seconds.
6) The AC and Air Recirculation lights will light up and flash at different points during the 7 second hold-down.
7) When the air recirculation light stops flashing, release the two buttons.
   
Now you have full control over the AC. When you hit the Defog button, the AC light will now illuminate. You can now shut it off if you so desire and get Defog air without AC!
 
 
Thanks again dudleyr!

Does this have to be re-done periodically and does the car automatically reset to the factory option as soon as it's shut off? Are there any negative consequences to performing this little "hack," as you called it?

Both answers are a definitive 'NO' to the best of my knowledge.
 
The A/C still automatically comes on when you select defrost. The only difference is that this time the A/C light comes on, and you have the option of turning it off.

I have been running the a/c 'hack' for several months with no issues. Not only does the car stay hacked, it even remembers that the a/c is off. I usually run with foot/defog most of the winter, and dont have to worry about the a/c coming on when it is above freeziing.
 
What prompted this was 3.5 hour trip in the rain at 50 degrees. The a/c ran the whole time, when at that temp, and for that distance the heat/defog would have been fine.
 
Keep in mind that the rest of the world is more frugal with gas than us. They would not stand for loss of control over the a/c. All we have done is make the car like most foreign Accords.
 
Grad - no problem reposting, the more that know the better. I did not discover this just dug it up from some older posts.

Can you restore the factory settings if at any point you want to or do you need to disconnect the battery? I just want to make sure because that might have a small effect on resale value. Otherwise, I'll do it simply because I've never had a car with A/C on no matter what when the defog is on.
 
Don't mean to ask so many questions.

Hey buddy, how else can you learn other than by asking? Don't sweat it, and ask away.
 
I believe a battery disconnect/reconnect should do the trick, although honestly, I can't say for sure. Dudleyr, can you field this one?
