Disable a/c compressor on defrost mod

I'm hoping someone knows which wire I can "modify" to disable the a/c compressor from coming on automatically when defrost is selected and only come on when I push the button. I know there's certain times it's beneficial to use but I think I'm capable of deciding that for myself :confused:

You don't really want to do that. It coming on serves two purposes that I know of. One, it helps to remove the moisture from the air which aids in better defrosting and prevents frost/ice inside. Two, it helps to keep the ac unit lubricated and functioning thus the seals don't dry out preventing leaks and the unit doesn't seize up.

Good luck if you find a way to do it.
