I have the truck listed above it is the 2500 model (i saw your video you are good). I have a problem I have a clicking in the dash area.
i took it to a dealership in the area he said it is okay he said just turn the radio on. I do not listen to the radio when driving (i had a towing company until a got sick in 2010 lost it. I am not working and cannot). I try to do myself if I can. Do you think it sounds like the actuator blend door? How many are there? Thank you.
Do you
have the same problem?

If you change the temperature settings does the noise change? Also, do you have two temperature setting for dual temp control for each side? Let me know and we can go from there. This guide will show where the blend door actuators are and how to change them:

It was doing it just in A/C [and yes I have dual controls ]. I turn it up halfway and it will stop, but now it is doing it all the time. I thought it was the controls and I replaced it still the same.

So which temperature control were you turning up half way the drivers or passengers side and the noise would stop? If you have two temperature controls then you have two blend door actuators.

Yeah it takes two one for each side to control each sides temperature. Let me know so I can get you the correct information. They are usually not too bad to replace.

I posted a diagram of the panel you must remove and the screw locations. Also I posted the re-calibration of the new actuator. Please read before changing it. Let me know how it goes.

Sorry going back to you I have been down. I disconnect the actuator at the bottom the one in the middle by the hump on the floor. It is still ticking. Is there a second one if so where is it located? I hear it. Can you help me find it? Thank you, Jim

You said the driver's temperature control adjusting that stopped the clicking? If so what is the problem you cannot find the driver's side temperature door actuator? There is only one for each side for the temperature control.

My truck's heater defrost/heater has not worked on the driver side or middle vent. Found that the blend door motor behind radio is not working all others do. Why have I not been able to find videos which apply to this? Every one has only the easy ones to replace.
Thanks

The driver side vents would flip from AC to very hot air. I watched the video and replaced the blend door actuator. Did the re-calibration by disconnecting the battery for about fifteen minutes, reconnect and turn the truck on for one minute. Turn off a few minutes and turn on again two minutes. I could hear a ratchet sound during the process. Now it is hot all the time and very little air volume coming from the passenger side vents.
What can I do to fix this?
Thanks.

Looking at your diagrams, it appears I replaced the wrong actuator. The one I replace is shown in your photo below under the cowl on the passenger side. Is the correct one under the top of the dash? Do you have a video showing how to get to it?

That is correct. That is not the actuator. The correct one is under the dash, left side above the fuel pedal.

I attached a picture and the procedure. Easy replacement.

Now I am confused. According to what I have read, the actuator on the left over the gas pedal is the mode door. Most of the videos I have seen state that the hot/cold on the driver side is regulated by the actuator on the right side underneath, the one I replaced. I even think the 2CarPros video stated or implied that. But the diagram on the 2CarPros article suggested that the driver side hot/cold was the actuator on the top right side (not the recirculate). So I am thinking that I did replace the correct actuator, but that either my replacement part is not correct or I did the re-calibration wrong.
I opened the actuator that I took out. It did not have the metal under the large gear, nor the track on the board like all the ones in the videos have. I do not know what that could mean. Outside, the actuators look the same.

If you have dual control or left and right control, that is the left side.

If you have only one control for both sides then it is the one on the right side.

Since you said only the left side goes warm, it sounds like you have dual control.

Hot air from drivers side only when A/C is turned on. Sometimes it blows cold and other times it s hot air. It has a mind if its own. Which actuator do I replace and what is the part number?
