Hello: I have bad news for you, if you run the actuator without it connected to the door the actuator is ruined, it will have to be replaced. After replacement the system has to have the doors (actuators re-calibrated.) re-calibrated. This is done with a Tech 2, A GM special tool.

    Not true...I replaced the one on the passenger side of my 2006 Impala and I did not have to take it to the Chevy dealer for anything.

  • Joe Nov 16, 2013

    Agreed. the fix on the passenger side is very easy to do. I am about to tackle the drivers side now, but there is no special calibration required.

Heater blows hot on drivers side cold on passenger side


it depends on what model and what options your Journey is equipped with. if it has a dual zone control climate control, it sounds like the blending actuators are not aligning properly or the blend doors are not adjusting to cooperate with the main climate control system. the temp. of the vehicle is controlled by Blend doors in the h/vac system that is thereby controlled by the body control module of the vehicle. the module is a computer that controls all functions within the body of the vehicle. the module should have problem codes that should isolate the area that needs attention.
the body module controls the blend doors in the h/vac system, the doors that open and close in the vents by the heater core that controls the temperature that is ultimately expelled the correct temperature that comes out of the vents. if the settings on both the drivers and passengers control knobs for example are on cold, and one side is hot and one side is cold, then there is a problem at the module level or most likely the blend door is the problem. most likely the actuator ( the motor that runs the blend door and controlled by the module) is not operating properly. your dealer will hook the module up to a diagnostic computer and retrieve the codes ( if any) and isolate which blend door is not working correctly.

usually its just a blend door actuator that needs replacing. to rule out heater core issues, if there is no excessive condensation on the windows and coolant on the carpet, then most like it's a module or blend door issue. if it's a single mode climate control, the same is true but puzzling b/c in that case, both passenger and driver h/vac system is designed to push out a consistent temp for both side without the option of variation on either side. again most likely a blend door issue.

hope this helps

My 2004 Avalanche ' heating system will not heat. No matter what the setting it either blows no air or cold air and it is 25 degrees outside so this is a problem. The engine is up to temp and I have tried...


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).

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.
