I have a 2005 Cadillac Escalade with a climate control that has a mind of its own.I can adjust the controls with no results and then,when I am least expected,it will come on and freeze you to the bone I can turn on the a/c on auto or manual,it makes no difference.It does however blow cold air when it decides to work.It will show that the fan is wide open but it does not blow.I drove it yesterday and the fan was wide open and when I stopped and got out,the fan kept running after the key was removed from the ignition.
