The procedure is the same for most GM blend door actuatorsfrom 1990-2013 (found in many vehicles made by Chevy, GMC, Buick, Pontiac, ...
I never heard about a need to "reset" or replace a blend door.
If a/c, you probably need some Freon recharge. My 2005 Bonneville had this problem with the a/c. I looked at the blend doors for hours, before getting a clue about the low Freon. You'll probably need to go to the dealer or an a/c specialist to have it checked. It may ony need 1/2 a can of Freon to fix.
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?
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).
Disconnect and isolate the battery negative cable.
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 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.
Disconnect and isolate the negative battery cable.
Remove the glove box from the instrument panel.
Remove the three screws that secure the blend door actuator to the passenger side of the HVAC air distribution housing .
Remove the blend door actuator from the air distribution housing and disconnect the HVAC wire harness connector from the actuator.
Remove the blend door actuator from the vehicle
Position the blend door actuator into the vehicle.
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 .
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).
Connect the HVAC wire harness connector to the blend door actuator.
your actuatior foe the drivers blend door is stuck. try unhooking battery for a few minutes have both on heat and hook back up and start up. the actuators will run thru a learn mode and sometimes this will free up.if not you will need an actuator
