From the FSM "On air conditioned vehicles, outside air can be shut off by opening the recirculating air door."
I looked inside the cab on the passenger side floor and I see nothing to open or shut anything. Anyone have any idea how to accomplish this? It is Chapter/page 24-2

 

I can go in recirculate mode by sliding my horizontal lever above the vent buttons all the way to the left. Sliding a little bit to the right at the indent takes it to fresh air mode. Not sure I understand your question.

 

These are my controls. I do not see how to close the outside air intake for the HVAC on it. The point is to just cool the inside air and recirculate it. Edit- now that I look at the picture the car with the circle arrow might mean putting the lever all the way over does it???

 

10-4. All the way to the left with the car logo below it. Then when you slowly slide the lever to the right you can kinda feel it go out of recirc mode into fresh air mode. Only the leftmost 1/2 - 1” of the slider is recirc mode.

 

I don’t think there is a recirc mode for the heat end. I live in nc so don’t really use the heat much. And to tell you the truth, Dodge didn’t exactly make it easy or clear how to get in recirc mode.

 

OK. I never noticed that feel you mention but this confirms for me I need the system serviced.

 

I’m not sure where the diverter is located.

 

Well the door it opens and closes is under the passenger side of the dash.

 

If you cant feel a difference or the point at which it transitions from recirc to fresh air when sliding the lever then I’d be suspicious that it is even working. It’s notan overly obvious feel but it’s there.
