My 2002 Durango has this issue. It is the little gates that open and close to direct air flow to the feet, to the windshield, to the vents, etc: The control arms that open and close them are broken or have fallen out of their sockets.
It is very expensive to fix. I suggest that, unless you live where you need A/C all eyar round, just open your windows and buy a plug-in fan for your dashboard. I was quoted over $1000 to fix it.
floor it You don't
It's a Dodge thats why.
If your talking about 2005 Dakota floor mats then yes! Correction: This is not correct. The 2005 Dodge Dakota was built on a new chassis. The floor pan on the vehicle is different from the 2004 model. If you have custom fit mats for the 2004, they will not correctly fit the 2005 Dodge Durango. All the major floor mat manufacturers including Nifty Catch-All, Husky Liner, WeatherTech, Avery's Mats, Lloyds Mat and Highland have different part numbers for the 2005 Dodge Durango versus the 2004 Dodge Durango
Pick up the floor piece, the third seat gets exposed. Fold the seat back and you have the third seat.
The lift gate on a 2003 Dodge Durango can be opened from the inside if the latch is not working. There is a latch on the floor close to the door that can be tripped with the use of a screwdriver to open the gate. The cable for the gate might need to be repaired after this.

Check your heater core. You may also have noticed some moisture in the passenger floor.
Turn the key on, engine off, press the gas pedal to the floor three times. cycle key and light should be off.
Check the dimmer switch on the floor and the electrical connection to it. It may be corroded.
There are multiple places one can purchase official Dodge floor mats. A good place to start looking is a local Dodge dealership or the official Dodge website.
Dodge Ram floor mats can be purchased from the manufacturer themselves, Dodge car dealerships or online auctions sites such as 'eBay' or 'Autotrader'.
This most likely cause is a faulty high/low beam switch on the floor.
