1. Locate the blend door actuator. The actuator is located behind the dashboard, usually on the passenger side. It is a small, rectangular motor with a wiring harness and a linkage arm.
2. Disconnect the battery. Before beginning any work on the electrical system, disconnect the battery to avoid any electrical shorts or other accidents.
3. Remove the dashboard panel. In order to access the blend door actuator, the dashboard panel may need to be removed. Consult the vehicle's repair manual for specific instructions on how to remove the panel.
4. Remove the old blend door actuator. Disconnect the wiring harness and the linkage arm from the old blend door actuator. Remove any mounting screws or bolts that secure the actuator to the dashboard.
5. Install the new blend door actuator. Install the new blend door actuator in the same location as the old actuator. Secure the actuator with any mounting screws or bolts. Connect the wiring harness and the linkage arm to the new actuator.

The most likely problem is either the blend door actuator or a broken blend door itself.
Both are only accessible by complete removal of the instrument panel(dash).
The blend door actuator can be tested with a Chrysler factory scan tool hooked up to the DLC(data link connector). If blend door actuator is working when tested with the factory scan tool, then blend door itself is at fault.
The only other way to test the blend door actuator is to test for 12v at connector, but you would have to remove the instrument panel in order to gain access to the actuator

The most likely cause is a failed blend door actuator; however I recommend a little troubleshooting. First, can you hear a clicking sound behind the dash when you turn the setting to hot? If yes, it is certainly the actuator stripping its gears. If not, check to make sure the heater hoses are both hot as they connect to the heater core at the firewall (in the engine compartment). If one or both of the hoses do not get hot, there is a blockage caused either by an air bubble or a stuck water control valve in the heater hose. If the hoses are both hot, the indication is again the blend door actuator.

Below are instructions for replacing the actuator. Look at the diagrams carefully--the big arrows point to the front of the truck and the actuator is on the side of the heater box above the outlet duct that runs to the driver's side of the floor. Also, the actuator is expensive, so I recommend you make sure it's bad and shop around a bit to get a good price. To check out the actuator, first see if you can turn the blend door by hand. If you can't turn it, maybe it's jammed. Also, reconnect the actuator after removing it and see what it does when you turn the heater to hot.

Removal & Installation

Picture of actuator:

there is a blend door actuator for the laredo and if is bad the air wont come out here is a pic of what it looks like and how to get to it


The single zone heater-A/C system is equipped with a single blend door actuator. The dual zone system has two blend door actuators, one for the driver side blend-air door and one for the passenger side blend-air door.

1. Disconnect and isolate the negative battery cable.
   
2. Remove the glove box from the instrument panel.
3. Remove the three screws that secure the blend door actuator to the passenger side of the HVAC air distribution housing .
4. Remove the blend door actuator from the air distribution housing and disconnect the HVAC wire harness connector from the actuator.
5. Remove the blend door actuator from the vehicle

to instal

1. Position the blend door actuator into the vehicle.
2. Install the blend door actuator onto the passenger side of the HVAC air distribution housing . If necessary, rotate the actuator slightly to align the splines on the actuator output shaft with those on the blend door cam .
3. Install the screws that secure the blend door actuator to the passenger side of the air distribution housing . Tighten the screws to 17 inch lbs. (2 Nm).
4. Connect the HVAC wire harness connector to the blend door actuator.
5. Install the glove box into the instrument panel.
6. Reconnect the negative battery cable.

I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.
