I have a 2013 2500 mega cab big horn 6.7 diesel and my air conditioner will not stay working ... changed the blower motor worked until i shut truck off then didnt work.. changed the resistor same thing happened... also changed the relay refuse ... any advice will help .. getting frustrated.. only thing i can think is the control module or the fuse box itself... a guy used his 10 thousand tester couldnt get it to respond.
