Probably the door mode actuator. If you take it to the dealer they have a tool that was distributed to them to reduce the repair time from several hours to less than an hour.
Worth while to get them to fix it as it is not an expensive part. It is tough to see and if you are big it becomes more cumbersome and frustrating.

Your front blower motor has gone out. There is a front and a rear blower motor.
My ac blows fine through the overhead, floor and side vents but intermittentely throught the front vents. What might be the cause?
There may be several reasons why the air only blows out the front vents and not on the floor or the defrost on the 2003 Dodge Ram. The fuses may be blown, or the heating coil is not working correctly.
1st bet: Does it smell like antifreeze? Leaky heater core. 2nd bet: Worse after rain or car wash? Leak under cowl vents (the vents in front of the windshield. Good luck!
Without testing a guess would be a blend door or actuator or maybe a control problem
This is the same on all cars. When the air flow is OFF in a section, the it blows stronger to the other vents. In this case the ones for the windshield. This makes defrosting quicker so you can start driving safely sooner.
Your heater core has failed.
some thing is probley cloging the vents take it appart and ckeck.
2003 crown vic air conditioning vent dont blow
the accuator, located in the rear passenger side is bad. the controls in front when turned go to an accuator in the rear there are two of them one for hot/cold and one for the vents.
Because the air selector died.
It vents tank fumes so is usually under nearby.
