Air conditioner in my 2005 Endeavor seems to be working, but very little air is coming out of vents.

Some times, it can be many causes
settings, gass scape from system,ac relay out of range
Anyway, read pressure of system high pressure, is good and low pressure is good too make vacuums to recommend psi put gass

a low freon charge will cause the system to cycle a lot

No air coming from air conditioning vents

1. Check the air conditioner fuse and replace as necessary.
2. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
3. Air conditioner low pressure switch defective. Replace switch.
4. Air conditioner fan resistor pack defective. Replace resistor pack.
5. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary. Air conditioner has a smell when used
   1. The air conditioner evaporator drain hose is blocked or partially restricted, allowing condensation to build up around the evaporator and drainage tray. Clear the drain hose where it exits the passenger compartment.
   2. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

There is a deflector vent door actuator motor that is not working,the dash will have to be removed to replace it.

May have stopped up cabin filter

you could have a vacuum leak..if your system works off vacuum....or if it is like GM products it has a little black box behind the ac controls in the dash

thereis an actuator controling the flap t may be cracked causing the problem

check the cabin air filters in the glove box there is a door in the rear of the compartment

being that it a dodge product they probably have used a vacuum based motor to switch where the air comes from. If this is the case then you must have leak somewhere. These are not easy to find they can take a lot of time or be quick it depends on the leak. to clarify does the heat or vent come out the top? is it supposed to?

The vacuum line on the drivers side of the intake manifold just below the throttle body fell off.
