Changing the blend door actuator

I would agree that this appears to be the issue. However, the procedure is attached and it doesn't have you remove the column. There should be access once you remove the cover under the column.

Let me know if you have questions and we can go from there. Thanks

The Left blend air door is what controls the temp of the air for the driverside. The fan speed is what controls the amount of air coming through the system.

From what I can tell the actuators are interchangeable even though the part numbers are different. The aftermarket parts websites only list one part for these actuators which supports the idea that they are.

Sorry for the delay. I have been looking numerous times for this information. Not only did they not publish a procedure for what you are looking for but they say that the frame and column do not need to come out to do the actuator.

I attached the process closest to what I can tell you are asking for. I am thinking that I am not understanding the component you are trying to change. Is it the actuator for the driverside door? If so, the first attachment is the process for that actuator.

Okay. Here is the process for the steering coupling. Hopefully this gets you to where you need to be. Let me know if there is another component and I will see if they have that as well.

You have a blessed weekend as well.

Sounds great. Thanks for the update. Please let us know how you make out. Thanks

Okay. So you have hot air on the passenger side but all the vents on the driver side are blowing cold? What happens if you turn the heat all the way to cold? Clearly passenger side is operating properly so it should be cold but I am wondering what happens to the driver side. Does it match the temperature on the passenger side or does it not change at all? Get warmer?

Depending on what happens with this, we may need to remove the actuator and plug it back in and change the temp. The actuator should move respectively. If it doesn't move then we have an actuator issue. If it does move, then we need to check the door inside the box.

Sorry for the delay. I guess I didn't understand the issue that way. If you have no air coming through any vent on any vent setting then I suspect you have an issue or restriction on the heater core for that side. The heater core has two sections or division for each side. This allows both sides to have different temps. I suspect you will need to pull the air box out and see what is wrong. If you have a borescope then you can stick the camera in there and see if the heater core is plugged but clearly we have an air flow issue on hot only and that really can only be the heater core.

Let me know if you have questions about this.

Okay. I understand. Here is what I suspect is happening. The air always passes over the evaporator which is what cools the air when the AC is on. However, when you turn it to heat, the blend door routes the air over the heater core. As you can see from the picture this is in heat setting and the blend door is allowing the air through the heater core which heat it. The second picture shows this. I drew a green bar where I suspect the heater core is plugged blocking the air flow.

The fact that you have no air flow on only one side only during hot air, you have to have a blockage on the heater core or in the air box.

Hopefully this makes sense.

I have not done this job either on this vehicle so I really don't know what to expect. I attached the process and it doesn't seem too tough but again, they always seem easy on paper.

I would suggest removing it (depending on what you see with the scope) and just seeing if you can push air or water through the fins of the heater core. Not through the passage of the heater core where the coolant flows but where the air would pass over it. If you can't feel the air or see water flowing through it then clearly it is the heater core that is blocked. If not then I guess there is something in the HVAC box but I expect it is the heater core.
