My husband likes to drive with the windows down And A/C on at the same time. I'm trying to explain that he shouldn't do that but I have nothing to back it up...The A/C in our last two vehicles mysteriously stopped working...

Thank you -I'm sorry this all I got for you -however unless the AC is acting up continously while in operation, when the window is down due to temperature differences-

Hello, here is one way that it could harm the ac. The out side air has dirt in it from the road and this could clog the evaporator core if the ac unit is set to max or recirculation, also if you smoke this would clog it too, and it would stink.
