Question about 2004 Dodge Ram 2500
Air flow is being restricted by a "damper" or the actuator is not pushing the rod to open the vent from the outside? I've tried to pinpoint the spot and it seems to be behind the passenger seat air bag hardware. I have a friend that is helping take off the trim and dash. Am I in the ballpark?

There is a actuator on the right side of your leg while sitting in the drivers seat under the dash. It has a plastic rod for actuation manually actuate this diverter and should be the problem.

It sounds like your electronic vent actuator has gone bad, it's common to go bad and may need to be replaced. There are tinny gears that wear out and the vent actuator stops working. You can try this, turn the radio off first so you don't have to enter the reset code to activate your radio. Disconnect the battery for 30 seconds and reconnect it, if the actuator has lost it's base line and stuck in the open heat position, this will reset it, just make sure the setting is to cold and off before disconnecting and reconnecting the battery. If this does not work, then it's a bad actuator and Auto Zone should have the part you need and will have the step by step instructions for you to the job you self, I believe the dealer is a $415,00 repair cost for this. Good luck and keep me posted.

Your heating and air conditioning system is controlled by the Body Control Module (BCM). Any diagnosis should begin with scanning the (BCM) for trouble codes to determine the source of the problem and/or which circuits and components are involved.
If a failed mode door actuator is, in fact the problem, the instrument panel must be removed to gain access to it.

Dodges have issues with the plenum door actuators. You can read online for more information. Sounds like your plenum door either stopped where it was or went to a default ( closed) position. The plenum door mixes the air and moves to allow the desired temp air to pass thru it.
I think you can see the tip of the actuator shaft sticking down vertically from the bottom of the plenum box, just to the right of the transmission hump, where the passengers left toes would be. Most likely you will have to remove the complete plenum for repair. ( pain in the a**). Good luck.
