Hey all,

2006 Jeep Commander 4.7V8 with every option but dual climate.
Recirc door is staying open causing the AC compressor to work overtime, I imagine. Would like to fix the door issue rather than replace the compressor and the door issue before too long.

I've searched youtube for a fix, but only get older Jeeps with the issue. Anyone have a video on how to fix or can shine some light on this issue?

Yes. Some here had a wright up and part number. I have to get to my laptop to find the link (in the phone app at the moment)

That is the correct part number, yes. Thank you!

Unfortunately, I can't find any write ups or videos on how to replace this. I'm beginning to think the entire dash / shifter / steering column will have to be removed and that's the reason for lack of information as I doubt many people have tried this repair. If that's the case, that's truly a terrible problem as I'll never be able to do this job myself.

Anyone else have the recirc door issue? The air blows constantly though the top vents and it's really annoying. I'm sure the compressor will go out soon too as the thing probably works overtime to cool the continuous outside air.

I have the factory service manuals (huge books) at home, visiting family for the holiday, I can look it up when I get home. I just read the descriptions of the different actuators I didn't think any them were terribly difficult, but I was skimming through for the recirculation flap not shutting.
Thinking about it I might have the digital copy on my laptop, if I do I'll let you know where the defrost actuator is and what to do fix the vents if it's listed.

Btw the factory service manual can be extremely vague on many points,ac compression w dual ac was trying to find out what the correct freon psi and oil amount for the compressor only listing was for the compressor it didn't have and even that lacked the information I was looking for.

Unfortunately the commanders and grand Cherokees of these years do not have that many write up and videos on them yet. The KJ forum was invaluable helping me with the details swapping the 3.7.

Wait a second. Do you mean the defrost vents? I was assuming it was the re-circulation door not closing so the AC is not working as effectively as it could, but otherwise air was going out the vents properly.

BTW I do have the service manual on this computer so I should be able to find what you need

As far as I know the recirc door is stuck open. Air flows through the vents (whichever I set them on) accordingly. If I set to feet, air will flow on the feet. Head, to head. Defrost to defrost. But the air always flows as the recirc door won't close when I set to recirc air.

Ok cool. I've got the same problem. I mistook the air through the top vents for defrost.

I'll get a chance to look to the FSM tonight.

My recirc function stopped working a while ago. I could tell something was wrong, and it turns out the recirc door was broken off, and eventually fell down, blocking the blower from pushing air out of the vents. I was able to remove the blower motor and reach up and pull out the recirc door. I now have airflow, but no way to use the recirc function. I am trying to see if I can find a how to of how to replace just the recirc door. I found another thread where someone else said they were able to replace the recirc door without removing the dash/hvac housing, but they did not respond when I asked if they had more details/pictures.

I found good instructions on the actuator but not removing the assembly, somebody did say they got theirs out and replaced it rather simply. I'm not sure what the job takes.

I don't know if anyone is having better luck with this. Almost certain the rec door is stuck open on mine. Just fixed the AC tonight (swapped compressor, new dryer and condenser). Weird thing is the passengers side front is noticeably warmer than the drivers. We do not have dual climate. What could cause this?

I did peek past the glove box and could see one of the actuators and gears but it didn't move no matter what setting I set it to.

I've had a similar problem, and before getting into any trouble taking the entire dash apart, just take the actuator off. There's a gear that connects the actuator to the recirculation door, and I've found that the gear is very easy to break. In fact, in all the A/C issues I've had with this Jeep so far, they've all just been broken gears.

The gear connecting the actuator to the recirculation door is a pretty easy part to find and replace, and you really only need to remove the glove box to access it.

Just looked at my actuator for the reticulation, the gear on the actuator is broken, the corresponding gear on the flap look fine.

Where did I get the gear for the actuator? is it with the flap kit?

This is the gear that commonly breaks, and may be the gear you're looking for.

Yep that is the gear. Thanks!
Mopar part# 68072190AA
3 T15 torx head screws holding the motor to the housing.

What the heck is the deal with lining up the two gears when reinstalling?

The replacement gear can only be installed one way, but when it's give power and the AC selector is turned to the different setting the motor seems to spin around randomly, stopping at odd places that can't possibly be aligned with the gear on the flap.

I do have the FSM just no time to dig through it, if it's even covered.

Ah, got it!
thanks to NLAN's post!

Pull the plug as the gear turns line it up and tighten it. Works like it should. The only thing I'm still checking is how the floor vent works. I can see the re-circulation flap working. Honestly the hardest part is aligning the gear.

It took me about 45-60 min because i had to negotiate with the actuator motor to get the motor sprocket lined up with the sprocket on the housing. That was the hardest part, since i am not experienced with this type of stuff and didnt want to break the motor by forcing it to turn by hand, i just hit the recirc button, let the motor spin and pulled the plug from the actuator when i needed the motor to stop turning so i could line the 2 sprockets lined up. Also, there are grooves in both sprockets that give you an indicator of how they are supposed to line up logically.. No special tools needed, just a torx key and determination.

Does anyone know if the floor vents are tied to the recirc flap?

I thought when I moved the flap by hand the floor vents shut off. But I'm not sure because I was doing several other things to it at the same time.

My gear broke a couple years ago but I kept hearing how hard it was to fix so I avoided it. Finally I talked to a friend that is a Jeep tech. He said the blendoor is the hard one and that the recirculate door was easy.
Popped out the glove box and there it was. Three screws and the actuator was out. Checked to see if it was working and it was.
New gear from Amazon and it was 30 min to install and reassemble.
I'm sorry I waited so long.
