Is there a way to modify my rangers AC temp control to trick it to run colder? Ive already done other mods like using aluminum tape over some parts of the ac lines, and replacing my freon with Propane/Butane but its just not enough. I live in a tropical climate and I need it to be as cold as possible. I dont really care if I risk freezing anything, cause Im never driving for more than half an hour straight anyways
