Hi guys,
I really want to disable AC compressor because whenever I turn the front windshield defogger on the AC turns on automatically and then it drinks fuel like gatorade. Is there a seprate fuse for AC compressor to completely disconnect it? I don't use AC at all because it's always cold.
Thanks!

Even though you never use A/C, the system has lubricant in it and wants to be cycled regularly (Once a month would probably be okay). A defeat switch would be preferable if you want better resale value down the road. Plus, A/C defrosts better, should you ever need it.

Another one followed me home. Can we keep it?

There are a number of situations where the vehicle will disable the AC compressor. I wonder if you could use a switch/relay, to interrupt the signal that reads “compressor speed” to disengage the clutch?

using the a/c with defrost as it is doing helps reduce the moisture in the cabin which helps reduce windshield fogging

back in the old days, we would do it manually until the window was clear then switch the a/c off
