Hi all,

I'm wondering if anyone has successfully de-coupled the AC and Defrost in the 6th-gen Civics. I have a 96 DX and noticed that the AC comes on automatically when I turn on the defrost. I can, of course, simply hit the AC button and turn it off right away, but I know there are mods for newer Civics to decouple this function (and yes, I'm aware of the benefits of AC-air in defrosting windows).

My 07 Fit does the same thing, but someone noticed that unplugging a connection below the AC dials de-couples the AC from the defrost settings. Does anyone know if a similar mod is possible for the 6th-gen Civics?

Thanks.

I'd like to know the answer to that as well.

Hi neighbor!
I see how this can be done with the Fit, snip a single wire.

The 96, I've never heard of a mod you can do to it.
I can't see it (cutting a wire) in the diagrams for a 96 Civic --- since the diagram doesn't show what goes on inside the HVAC controller, and it's done within that controller.

Maybe a simple toggle switch to interrupt the AC request to the PCM would be feasible?





Oh BTW, I did the mod to my 12, and the AC still comes on every time I select any defrost mode.... I have to manually turn the AC off each time, but at least I CAN turn it off now when I want to.
