So, by turning recirculation on and off, I can hear the door moving. It's very quiet. But it's NOT the breathing noise I'm hearing.

I'm pretty sure I hear the expansion valve opening or closing. The problem is, it's happening every 7 seconds, and lasts for 10 seconds or so. The air in the truck has never been FREEZING, but I would say it's almost cool. I'm not sure how cold it's supposed to get. It is 100 F outside
