hello guys, my 86 W126, 420SEl, AC was working ok ( not cold, just little cool), but all the sudden it stopped, I press the all the buttons and nothing comes on, I checked the blower fuse, it is the little black box outside of the fuse box, but the fuse looks ok, it is not broken. ANy input is great appreciated!

and I searched many places, and most people has different problem than mine.

thanks again
