I would pull off the blend door actuator and swap it out with a new one. Or another option is to swap it out with one of the other actuators. The blend door actuator is interchangeable with the actuators for the mode-air doors and the recirculation-air door.

Disconnect and isolate the negative battery cable.

If equipped, remove the silencer from below the driver side of the instrument panel.

Disconnect the wire harness connector from the blend door actuator located on the driver side of the air distribution housing.

Remove the two screws that secure the blend door actuator to the actuator mounting bracket and remove the actuator

I'm having the same problem except on mine it's the driver's side that's blowing cold. Do you have the pictures in a finer resolution? I can't make them out and when I zoom, they are too grainy. Does the replacement require removing the dashboard? What's the general cost of the acuators? Are they readily available at like NAPA or other parts stores?

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.

Blowing hot air when set to A/C is almost always a stuck blend door, dead blend door actuator, or a cracked or disconnected blend door actuator vacuum line. The blend door is inside the a/c ducting under the dash, but the actuator will be accessible outside the ducting.

The temp blend door, or blend door actuator may be faulty. You can check this by watching the movement of the blend door actuator while you turn the temp selector knob. If the actuator is working, then it may be the blend door, or blend door lever broken. If these are ok then the control head may be faulty.

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
