Heater core?

We're about an hour. I don't have many opportunities to jet out for a few hours. Long work hours and young kids. But he is right by a fishing buddy of mine so next time I have a chance I will see if we can work it out. I had the heat on cause it was real humid out and my window fogged. I was trying to clear it and I'm paranoid to turn my AC on. Hell ... I'm just gonna drive with the AC on all day tomorrow and see what happens

Lol, I looked it up to see. Understand about the kids and all, I've got a 10yo and a 2 yo, just used to driving at least an hour to get anywhere.
