Position the carpet to access the front upper screw that secures the air inlet housing.
Remove the recirculation door actuator.
Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.

Ooops. Sorry about that. After going through every image of the HVAC housing provided by Dodge, unfortunately, there isn't one clear one that shows the location of all 4. If i'm not mistaken, there is one tucked up in the right corner, and then around rim of the housing. I would suggest starting from the first one you can see, and feel around the edge.
