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 blend door is stuck in cold position. That usually happens because the blend door actuator has failed.
You will need to test and replace the blend door actuator.
To replace the actuator you will need to take apart the dash and remove completely the instrument panel,d isconnect the connector, remove the four screws, remove the temperature blend door actuator and replace it.
The replacement is not a job for beginners, since you have to take apart the dash to access the actuator.
no it doesnt ... check out heatertreaters.net if you have to replace the blend doors .... but the actuator is directly behind the glove box...remove the glove box take out 3 screws and remove actuator and replace.....waa laa
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
to instal
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.
The control module or actuator is most likely the cause. You can manually set it for cold air until winter. Actuator is under the dash right by the blower.
most likely needs a LH (bottom) temp actuator. Located in the center of the dash on the bottom, you have to remove the hush panel on the rh side of the truck
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
no power to the heater blend door actuator.
