I just had the same issue (still working a/c issues with manufacturer) with my main brown connector for the ac being too hot to touch. it ended up being a factory terminal in the connection that was never a very good contact and had too much resistance in the connection to due corrosion or something.
too high of resistance in a connection is what you should be looking for. our ac systems rely heavily on 12v negative signals. check your switch wires with a multimeter for resistance on the ohm setting.
