I wonder if you all think I have the same problem, or something different? 2010 Charger Police, so NO dual zone climate control. With the Fan and everything Off, air is blowing through dash vents. Feels to be outside temp air. Just started doing this about a month ago. If I change the temp setting it does not effect the air temp coming through the vents.

So then we had a cool night recently, so I turned the heat on, setting it to the lower vents setting and warm temp setting. It worked as it should. After I turned the fan off, but left the vent setting to the foot well setting, the air did no start coming back through the dash vents. So it seems it only comes through the dash vents (again, despite the fan in the off position) when the vent setting is turned to dash setting (the one with the diagram of the body with arrow point toward chest).

A few days later it was warm (it's Florida, so we'll have a day in the 80's and then a night in the 50's this time of year) so I turned the a/c on max recirculate. I could still smell exhaust from cars in front of me, and real strong. I would not normally have smelled outside smells with the a/c in this mode, so I'm sure I was still getting the outside air.

I hope to fix whatever the problem is before Summer comes back around. What do you think?

Thanks.

"turning the fan selection to full off"? As in fan off, not full, then off?

As far as "auto setting" I guess I can't do that because I have a 2010 Police car with the basic a/c, so no dual zone, no auto setting.

Anyone advise if another way to calibrate, and what DTC's is referring to? I don't have my own scan tool and therefore am not familiar with all the acronyms.

Thanks.

Ddaddy: Those pics you posted from Service Manual. What manual is that? Is that a Factory Service Manual? CD, or book, and where do I get one? Thanks.

Can someone really dummy down the steps for me on resetting/recalibrating blend doors/actuators for a SINGLE ZONE climate control (2010 Charger Police)? Or, do I just need to take apart lower dash and replace part?

Thank you!

 

[ChargerPursuit]

Ddaddy - could you possibly post "23 - BODY/INSTRUMENT PANEL SILENCER - REMOVAL" page?

Thank you very much!

 

[ChargerPursuit]

Thanks man! You have been a great help to me, often answering someone else's question but one I had, but hadn't asked yet! Thanks again.

The Actuator Calibration function will either run automatically or it can be actuated manually


The automatic calibration occurs in two ways:
1. 10 minutes after turning the ignition off after a specified number of ignition cycles
2. Turning the ignition on after reconnecting the battery
Once actuated, the calibration function will run to completion even if the ignition is turned off. The entire process takes approximately 90 seconds. Upon completion, all air-door actuators should return to the position that the system is currently requesting.


To run the Actuator Calibration manually, you're in luck if you have the MTC (manual temp control) versus the ATC (automatic temp control). With the ATC you need the dealership to perform the Actuator Calibration using their diagnostic system. With the MTC you can perform the procedure yourself:
1. Turn the ignition to the On/Run position (but don't start the car)
2. Turn the blower motor control to the Off position.
3. Press the rear-defroster button down for five seconds and release it.
.

Perfect, thank you so much. I'll give it a try.

I've replaced the "mode door actuator" on my 06, single zone, beneath the drivers side and it is the rear of the two and a little tough to get to.

I had my wife do it as she is smaller and could get in the spot easier than me. LOL..

Did not need to recalibrate just swapping them out.

Thanks for added information. I still have my Jotto Desk console out and just replaced the HVAC controls with new one because lights were all burned out. Just been too busy to start pulling panels but want to get to it soon! I'm pretty skinny so hopefully this is one time being skinny is a good thing

 

[ChargerPursuit]

I tried the recalibration method twice, but unfortunately no-go. It was simple enough to try. So I'm hopefully off Monday (if the phone doesn't ring AGAIN), and will be working on removing old blend door actuator.

I was thinking, I should have ordered part/parts ahead of time like I try to do whenever possible, so that when I have things apart I can put new part/parts in right away. So I'm trying to figure out exactly what I need. To recap what my system is doing; everything works fine except recently it started letting in fresh air all the time, even when fan turned off. Wouldn't be big deal except now when on "Max a/c", still getting outside air mixed in as if not on "Max a/c" and I am stuck smelling exhaust fumes from junk cars in front sometimes, and takes much longer to cool off car at times. Like I wrote, just started doing this about a month ago.

So, I believe this is the part I need (not necessarily the brand I'll go with). But the footnote has me wondering if I need more than one? Is that footnote just for dual zone climate control cars? It states "most vehicles" so that concerns me. Thanks for any help. Here's what it says:

" : Heater Blend Door Actuator
DORMAN 604021 {Click Info Button for Alternate/OEM Part Numbers} Info
Recirculation Door (Controls Recirculate or Fresh Air Option); Main
Most vehicles use more than one Heater Blend Door Actuator and they often look very similar. To make sure you're getting the right part, we recommend verifying the part number on the original unit whenever possible"

 

[ChargerPursuit]

It states "most vehicles use more than one". You think that means interchangeable, and not that most vehicles have more than one installed? I see. I was reading it with a different meaning, lol. Thanks.

 

[ChargerPursuit]

I ordered one online to replace the one I think is bad in mine. If when I am in there and decide at the time to replace more, I run to the dealership and hope they have one in stock. Headed out there right now to remove panels and the old one. Thanks for all the help. Feel bad I kind of hijacked this thread. Hope it was all relevant enough to o/p's issues.

 

[ChargerPursuit]

I have the silencer panel off. Looking with a bright flashlight, I see the two actuators way over by the side of the center console. Can these actually be replaced without removing center console??? Even with my skinny arms??? I guess so because the instructions say nothing about removing center stack, and others have done it, but wow, they are waaayyyy back there!

 

[ChargerPursuit]

That's what I was saying in post 15.. LOL..

I believe it was an 8mm socket on a 1/4" drive with a little 1" or 1.5" extension on it and it is the rear one of the two for the "mode" door.

An "offset" adapter might help, but I dunno.. It is tight in there though.

Griz

I definitely read that and was thinking I was ok with my skinny arms. Granted, I only looked for a minute or two so far, but it looks more than tight. It looks out of sight and blocked out but other stuff, and too far away. I have to take another look. Thanks for the tips!

2nd look: I feel like I'm going to have to be looking up at it. Sure would be easier with driver's seat out and laying down with my legs toward the back seat. I am not sure how I'm going to do this. I'm not super tall at 5'10", but I have to figure out a way to have my head down on floorboard looking up at the underside of dash.

 

[ChargerPursuit]

PLEASE, someone who has replaced these on their own, tell me how you positioned your body. For the life of me, I can't figure out how to contort myself to get to the screws. I'm 5'10, 140.

 

[ChargerPursuit]

I'm sorry to keep dragging this on. I squeezed under there again today with a bright flashlight, and it looks to me the screws are the plastic thumb screws? Like maybe I need needle nose pliers to remove them? The head is black, and looks to be plastic and not anything I can use a screwdriver on. I don't know if all the 05-10 LX's used the same fasteners for these, but the new actuator did not come with new fasteners and I don't want to destroy anything. My next step (hopefully someone here knows though) will be to parts department at dealership to see if they have listing for the screws/fasteners so I can see the head. The next time I have to do this, it'll be so much quicker! Thanks.

 

[ChargerPursuit]

Called the dealership. The screws/fasteners are not listed as separate part and come as part of the entire HVAC box, which costs hundreds of dollars. Also, the diagram does not show the type of head on the screw. I'm stuck.

 

[ChargerPursuit]

I did contort myself under there yesterday. I found two of them. One I needed to remove the plate (three screws) that's between the actuator itself and the HVAC box in order to access the two screws that hold the actuator to that plate (wire harnesses and other things attached are in the way). Below that actuator is another one which is just held by two screws holding it and they are accessible. So this is why I had some confusion when reading the FSM which stated simply remove three screws holding actuator. I was trying to find three screws, when it's actually held by two screws. The plate between it and the box is held by three and the bottom by two.

I called the dealership again today, and they told me my car should have a total of three, but can't tell by diagram where they are. Not sure what third one does. Single zone climate control. I know one would be for temperature and one for controlling where air flow is directed, but what would third be for? And I didn't see a third one, but then it's hard to see around in there. I'm laying on my back, with my lower back on the door jamb, and my legs hanging out door, and my head resting on floorboard looking up. Going to try and find third one on my next day off.

Just trying to help anyone who is going to be doing this soon. I'll watch the video (thanks). Don't know if it's different for the next gen ('11 and up).

 

[ChargerPursuit]

That's a good video. He did a good job and he mentioned the one that I talked about that has a plate between actuator and HVAC box.

It looks to me the dash framework is different in the post '10's and maybe easier to reach them.

 

[ChargerPursuit]

I'm sorry if I come across thick, lol, but I'm still not sure if this diagram refers to single zone, dual zone, or both. I hope this will be my last question. Are all three actuators on single zone on driver's side? Or, is one on passenger side by blower, or is that just with dual zone? I'm replacing all three of mine now while I'm at it. Again, sorry if I'm just being thick.
