Ok... i've tried every combo. I've seen the recirculate light blink, and then turn solid... i've seen the recirculate light blink and then a/c turn solid... i've seen the a/c light blink and then turn solid... and i'v seen the a/c light blink and then the recirculate light turn solid.

in none of the cases did the a/c override feature work when in defrost mode.

could this be because i have a civic hybrid and they don't want this combo to work? there is an econ button that does things depending if a/c is on/off. anyway, i'll try this out on my brother crv. he hates that he can't override.

my s2000 allows you to override without any button sequence.

TIGHT it works, ya so use the a/c until it gets all defrosted and than turn it off whohoooooo

First off- did the a/c override and it works awesome, thanks

But, I think I found a sort of 'test mode' for the HVAC system while in the process of doing this (maybe any techs watching and laughing can confirm?). After goofing around with a few different button presses I found that the sequence of:

-all knobs turned as counter clockwise as possible
-turn ignition on/while simultaneously pressing the recirc and rear defrost buttons and holding them in (no pressing of the a/c) until the 'test' stops.

This all leads to some sort of system test in which the fan cycles from low to high, then low to high with recirc, then the vent position cycles from floor to dash to defog, and back again, I think a/c pops in and out for the later half and the air temp goes from cool to hot to cool again.

Yeah, sounds like I was just too tired when I did the a/c override I know, but it seems like some sort of calibration test or system function test used to make sure everything is working.

Just thought Id pass it on if anyone wants to amuse themselves further...

just rode in my friends new 04 recently, appears that honda turned off the "auto ac on" for defrost for the 04 model. so now its fully manual, one could turn it on and off when he wanted. i guess too many ppl complained.

[VtecDude]

I think its in the owners manual.. no?

[Bebop]

No, the 04 models still have A/C on during defrost (the A/C light never comes on) and can't be turned off. But, the trick works on the 04 models too.

For those of you still trying. The trick does not over rides the A/C. It still comes on during defrost mode, but the A/C light now comes on and you can manually turn off the A/C in defrost mode.

You guys are awesome. This fix works great!

It's dumb to use this thing in a cold weather climate, as the AC doesn't even act to pull the moisture out of the car's interior air when the temperature outside is less than 32 degrees F. This then defeats the purpose of having this option being mandatory.

Thanks again,
