You have a dual range HVAC system. It has two blend doors in the HVAC box, and only the blend door for the driver's side is working properly. You will have to troubleshoot, and possibly replace the blend door actuator for the passenger side.

blend door actuator not working

1 - Blend door actuator 2 - Mode door actuator 3 - HVAC wiring harness

NOTE: LHD model shown. RHD model similar. All vehicles are equipped with a common heater, ventilation and air conditioning (HVAC) housing assembly (1). The heating-A/C system combines A/C, heating, and ventilating capabilities in a single HVAC housing mounted within the passenger compartment behind the instrument panel. The HVAC housing assembly includes:

1. Mode-air doors (2)
2. A/C evaporator (3)
3. Recirculation door actuator (4)
4. Air inlet housing (5)
5. Recirculation-air door (6)
6. Blower motor (7)
7. Blower motor resistor (8)
8. Heater core (9)
9. Air distribution housing (10)
10. Blend-air door (11)
11. Blend door actuator (12
12. Floor distribution ducts (13)
13. Mode door actuator (14)

Sounds like the blend door actuator. It separates the driver and passenger side from getting air on the AZC system. Here are some instructions on replacing it:
The passenger side blend door actuator is used on all models equipped with Automatic Zone Control (AZC). This actuator is located on the front of the HVAC housing to the right of the floor panel transmission tunnel and cannot be removed from the passenger compartment without instrument panel or HVAC housing removal.

NOTE: This procedure is for AZC Systems (Passenger side only).

1. Disconnect and isolate the battery negative cable.
2. Remove the glove box door. See: Body and Frame\Interior Moulding / Trim
3. Remove the lower I/P glove box door surround panel.
4. Remove the dash assembly. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
5. Remove the HVAC assembly. See: Housing Assembly HVAC\Service and Repair
6. Unplug the wire harness connector from the blend door actuator.
7. Remove the 2 screws that secure the blend door actuator to the HVAC housing.
8. Remove the blend door actuator from the HVAC housing.

INSTALLATION - AZC (Passenger side only)

1. In stall the blend door actuator on the HVAC housing and tighten the two mounting screws to 2.2 Nm (20 in. lbs.).
2. Plug in the wire harness connector to the blend door actuator.
3. In stall the HVAC unit into the vehicle. See: Housing Assembly HVAC\Service and Repair
4. Install the instrument panel assembly into the vehicle. See: Body and Frame\Interior Moulding / Trim\Dashboard / Instrument Panel\Service and Repair\Instrument Panel Assembly
5. Evacuate the HVAC system.
6. Recharge the HVAC system.
7. Connect and the battery negative cable.

Hope it helps! If you need more, just send me an email at familyguy77351 at yah I wil be glad to finish helping you with more detail.

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

1. Remove the floor air outlet duct extension (1) from the floor duct (2).

To install:

1. Install the blend door actuator as an assembly with the actuator cam.
   1. Line up the heater/defroster valve lever with the blend door actuator cam slot.
   2. Line up the A/C valve lever with the blend door actuator cam
   
   
2. Install the blend door actuator mounting screw to the HVAC module.
   1. Tighten the blend door actuator mounting screw to 14 inch lbs. (1.6 Nm).
   
   
3. Connect the electrical connection at the blend door actuator (10).
4. Install the floor air outlet duct extension (1) to the floor air duct (2).

Picture of actuator:

y9ou can gain access to the driver side blend door actuator by removing the glove box. The actuator will be in the left corner of the glove box opening. If you remove the actuator you will be able to turn the pin. If you can turn it 360 degrees the blend door is broke.

If your lucky its only the drivers side. If you get the repair kit from chrysler it will come with instructions with pictures on how to replace the blend door without pulling the HVAC unit/Dash. If the passenger side is broken the HVAC unit will need to be removed.

Heater treater (google them) also have a metal blend door replacement and instructions online on how to replace them without pulling the HVAC housing.

There are two blend doors with actuators in models with separate controls for driver and passenger in the HVAC unit. Apparently the driver's blend door is broken/jammed, or the actuator is not working. You'd need to check a service manual to determine how hard it is to get to and repair the driver's blend door.

no u must remove the dash.

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.
