No a/c defroster?
I want to rig up a switch or something that will prevent the a/c compressor from coming on when the defroster is on. Where would be the best place to tap in? Sometimes I just want fresh air to blow instead of the a/c kicking on. Especially in the winter with the heat on. Kinda strange. All of my vehicles do it. This one will be the guinea pig, lol!

Re: No a/c defroster?
Yes, all vehicles do it to provide dry air to the defroster.
If you really need to do this I would think the easiest place would be at the pressure sensor switch on the rail. I'm pretty sure when disconnected it cuts out the compressor.

Don't know what else. I guess you can't have your cake and eat it too
