However, I think that may have been the problem so next time it defaults to the defrost at all times, I know where to look.

For anybody having the same problem just reply to this thread and I'll let you know where to look for this blend door actuator. Kind of a pain to access, but not too bad.

Thanks a lot to CHRYSLER TECH!

The "blend door" controls the temperature of the air by blending warm and cold air. That's why they call it the "blend door". If your air is coming out the wrong place (which is what this thread was about), the problem isn't with the "blend door", it's with the "mode door", a completely different door within the heater plenum.

If you are having a specific problem, start a new thread, describing your problem as fully as you can. Tell what year and model of car you have, and what you have done to try to fix the problem.

This thread goes back 10 years and almost nobody who posted earlier is still around.

Is yours a coupe, sedan or convertible? If it's a sedan or convertible, there's a "calibration" technique you can run. With the engine running, turn the temp knob all the way to the cold side. Turn the mode knob all the way to the defrost position. Put the fan switch to any position other than off. Then press the rear defroster button until you hear a chime. Let it go. The system will go thru some gyrations and give you a "report" in your odometer readout. A "0" is good.
You may have a bad control head. As you noted, the default mode is defrost, so if the body computer senses a loss of signal from the controls, it will put it into defrost.
Again assuming yours is a convertible or sedan, salvage control heads are fairly commonly available on eBay and in junkyards. The part is used in the sedan and convertible and in the Dodge Stratus from 2001 through 2006, so there are lots of them out there. It's an easy replacement which I would definitely try before tearing the dash apart.
The IOD fuse is the one in the middle of the fuse panel at the left end of the dashboard. Easily recognized by the "ears". You can pop it out with no tools.
