Does anybody know why my 2008 avalanche Randomly changes interior vs exterior air? I'd like to set it so that it only pulls interior air for the heat and AC but I constantly have to shift it back.

What do mean by randomly?
If you set it for interior with AC on, as your driving it will suddenly switch back to exterior?
How hot is it outside and how hot is the engine?
