[devildog1187]

So my front a/c blows warm air while the back blows cold ... I checked my freon an it is were it is suppose to be when I charged it last year so that rules out a leak.. my front a/c coils by the fan is doing what it is suppose to do it gets extremely cold but warm are comes out I checked my air the control that allows you to pick the air temp an that is fine any help will be greatfull

Blend door actuator or need to reset BCM. Unhook the battery for about 10-15 minutes and then reattach cables and see if the BCM resets.
