Air conditioner recirculating on 2007 Dodge Caliber

It's a hot day outside (around 100 degrees). I was driving back from a day at the lake. I turned my air conditioner on and turned on the recirculation to get the car cooler. As I was driving, I noticed the recirculation was off. I was pretty sure I turned it on so I hit the button again. I looked later, and it was off again. I hit the button again, and I watched it turn itself back off again. Even holding the button down didn't help. I stopped off to eat. When I got back in the car, I was able to run the AC and recirculation for 20 minutes until I arrived at home. I don't know if this was because it was so hot or if this is a sign of bad things to come.

This may be a problem with the switch, or the actuator or servo that changes the recirculating air mode from fresh to recirculate.Faulty Electrical circuits show up at higher and lower temperatures,as faulty mechanical opperations persists.

I'm having this problem with my Honda Civic except that the recirculation button goes off when I redirect the air, coming out of the vents, to the floor. Any thoughts on why this happens?

This sounds like the actuator or the door is causing high load on that circuit,,and the push button switch,may be faulty as well,and dont hold its on position,this may be a poor ground ,or just anything within this circuit,do you ever smell hot wireing? Are you replaceing fan fuses?
