Doesn't matter if the AC compressor is working, or whether the system is
charged or not (as long as you didn't rip it out)....As long as you have the
button, all your doing is tripping the electrical cooling fan with the AC

(the inside blower has to be on as you get a yellow light on the AC button).
Try it out!!
