Thanks for the write up and pictures. You'll make lots of folks happy here!

 

Thank you. It was helpful. Good explains either

 

:thumbsup: Thanks for the info.

 

Great write up. Thanks for your contribution and effort. I'm sure it will help many others.

 

I'm afraid it will! We do still see a fair number of people reporting this issue as a failure (myself included a few years back). The photos are great, and it's really nice that the OP has the dual controls so that he was able to document both sides.

 

Hi.
Glad to see this post!
Today I´ve found that´s not air conditioning flowing from the passenger side.
Next monday I´ll try to get an actuator here in Argentina....that´s my big concern at this time!

Regards
nacho

 

Thank you Tim,
Just a couple of quick questions.

The air conditioning is not working on my left hand side (driver side). It is working fine on the right side (passenger side).

The heating is working on both sides, and the air ventilation fan too.

The only issue is the air conditioning which is not cooling the driver side of the car.

Is this likely to the the Actuator?

thanks

 

Yes, those are the symptoms. No cool air. Only heat. Look at the last picture in my post...that's the driver's side motor as viewed from the drivers floor. You can confirm by unscrewing the motor and slowly pulling it away from its mounted position...you should see and hear the door flap shut once it disengaged from the motor holding it open. Then, you should feel cool air flowing (of course, now the hot air won't work though). This will confirm its the motor.

 

Oh, and if gravity doesn't flap the door shut when the motor is removed (like it does on the passenger side), you should see a metal(silver) actuator arm that you can manipulate manually with the motor removed.

 

Thank you very much Tim. I'll order the same one you ordered on Amazon. Really appreciate your help. thanks

 

Tim,

I received the item, made the changes, quite a simple process as you described.
Only problem is it has made no difference.

It might be I have an electrical fault.

As I mentioned above
- warm heating works on both side
- ventilation works on both sides
- only issue is no air conditioning on driver side, but heats ok

The car has 250,000km and is from 2007
Any thoughts?

 

Bummer, sorry to hear. Not sure what else it could be. Are you sure the new motor is engaged with the actuator arm and that its opening and closing? If it is, I find it strange that there would be no change in temp.

 

I'll double check that and revert. That is the arm that slides in the ear piece?

 

Tim,
I checked the actuator arm it is attached ok.

What I didn't mention before is that the zircon problem only started after I had my clock spring replaced in a garage.

When I told them of the zircon problem they said it was unrelated, but it only started after the clock spring was replaced.

 

Ok, starting to get out of my league. I don't see how the clockspring would effect it unless something electrical happened. Is power getting to the actuator? Can you see it, feel it operating when you dial the thermostat up and down? Is there any duct work under the driver's side that may have been knocked loose? I'm just grasping now. Sorry this one is turning out to be difficult for you. Let us know what it was once you get it diagnosed.

 

Power is getting to the actuator, I can feel it operating when I turn the thermostat dial.

The garage said he thought it was an electrical issue, but said to fully know they will have to dismantle the dash board it will be a big job they say.

Is it possible that the air con cylinder needs to be refilled?

I recharged the air con 6 months ago.

 

Tim, Thanks a lot for starting this thread! It has been very helpful.

I have a 2007 veracruz with dual temp controls. Driver side was only blowing hot air. Ordered the blend door and installed with the aid of your pictures. Turned the vehicle on and the controls to full cool and nice cool air came out. High fived the wife who was helping me.

Swung the controller to full heat and noticed the driver side started to warm up but would not get as warm as the passenger side. The new blend door is definately working, just not swinging the damper to full heat. I took the motor back out and noticed i could swing the thingy by hand and the temperature on the driver side would get hot like the passenger side. It swings smoothly and doesnt seem to bind. So, the door is swinging, its just not going to full heat under control. It will go to full heat with the motor off when swung by hand.

Im kind of baffled and plotting my next move. I cant really see how i put it back on wrong or it wouldn't be working at all. Looking at how may wires go to the motor im wondering what makes it go to full heat. Thinking about ordering another actuator and trying again. Also thinking about taking the motor off and seeing how much it rotates when going from full cool to full heat. Not sure what that would tell me though...

Any ideas would be appreciated.

 

Update...

i read another thread that suggested turning the car on with the new motor not in position, maually move the damper handle to the heat position, turn the controls to heat and let the motor turn to heat position, turn auto off and install actuator. I decided to try this thinking maybe I didnt have it "in the groove" of the ear thingy.

Took the actuator down which im getting pretty good at now. Turned the car on and moved the temperature from hot/cold and cold/hot while looking at the acutator which was still plugged in. It didnt move... About then my wifey said "im almost positive i gave you the new part"...

After looking at the pictures i took before starting we determined I had put the old part back in! When the controls were calling for full cool the compressor was engaged and sending cold air out. When the controls were on full heat the damper was not changing, but the compressor was not running so the air coming out the vent was cabin temperature.

We both got a good laugh when we figured out what happened.

Thanks again for the pictures and starting this thread! I couldnt have done the job without.

 

You get the help you pay for.

 

Funny! Glad it all worked out and that the thread was of assistance to you.

Hi Tim
I just want to say thank you again for this post;
yesterday I change the blend actuator, and it was easy following the steps.

As a humble addition, it´s good to get a short screwdriver, specially to remove the upper screw (I had to use a Victorinox).

If you ever come to Argentina, I´ll invite you a beer! :beer:

Tks & rgds

Nacho - Glad the write-up was of help to you! I would love to come down in the middle of our Chicago winters here! Lol.

Yes, a short screwdriver would come in handy...I used a Phillips head drill bit turned with a pair of pliers for the upper screw.

 

So my lucky day....

I have the dual climate control system.

Hot on the passenger side and cold on the driver side when set to full heat.

Control set to floor but blows from the floor and the face.

Any suggestions? Not really sure what part to replace in this scenario?

 

I replaced the passenger side actuator and all is well. I also swapped the lever from the old one to the new one as mentioned above.

I also found that connecting the the new actuator to the wire connector before mounting, turning the car on, and turning A/C on to the Coldest setting moved the lever to an position for easy install. The lever/rod on the vehicle connected to the "door" also needs to be in the down position. Hard to explain but basically if you move the lever on the car side up and down with A/C on one position will blow out hot air other position cold.

 

Driver's still blows warm air

Replaced actuator on blend door it works but still blows warm air

When you remove your actuator, you can manually move the blend control door by moving the metal rod on the mechanism. If you go to one extreme you will get cold air; move to the other extreme and you will get warm air. If you can vary the air temp in this way, the actuator is the most likely culprit.


You have to make sure the mechanism is captured correctly in the actuator. Plug in the actuator, set the car for max heat, let the actuator move in the appropriate direction, then unplug the actuator. Move the car's metal rod control to the extreme heat position, then assemble the actuator to the vehicle.


I will note that I just replaced the passenger's actuator with a new part from the dealer and the new actuator was dead! The actuator would not move. I returned the part to my dealer and found the part at another dealership--sure enough it worked properly.




Hope this helps.

 

I'm in a turkey coma at present, but let's look at your issue. Control works on one side, but not the other? If the door is working (moving!) then you should be getting cold air if appropriate. Both sides are fed commonly for A/C purposes, and it's the doors that control the result.

 

perfect tnx

 

Dorman replacement blend door actuators for Azera/Sonata/Santa Fe/etc. are as follows:

Drivers side actuator 604-308 (blue plastic lever)
Passenger side actuator 604-310 (white plastic lever)

They are available from RockAuto for about $50 each. I just replaced the passenger side unit on my 2008 Azera...

 

Just wanted to say thanks to Tim for the post! It made the job so easy on my 2008 Elantra, which was pretty much identical to your pictures on how to remove and replace. Got the part in today, cost me $36, and took me about 30 minutes total and I now have heat again. It probably would have taken me many hours and a lot of frustration if not for the pictures.
