sometime early this winter that just passed, i turned off the little a/c button that normally has a little green light on it. well now its summer and i pushed the button to turn it back on and the green light wont come on and it blows hot. im guessin that this button is for the a/c compressor? well anyway i bought a new button hoping that it would be the problem and it didn't fix it. anyone have any idea what the hell is wrong?
