I had my actuator replaced by the dealership a few weeks ago. It sounds a bit like the overshooting the target is already back...

Does anybody now where to find the Dorman one? Everywhere I look it is out of stock. RockAuto has been out of stock for weeks now.

I am so glad i found this. My problem is very similar but there are more noises at play. It goes on for about 5 minutes after turning the car off. I am thinking is something else besides the actuator.

I think it is the same thing. I would replace it and see if you still have a sound coming from it.

I also found 1 in stock at amazon and ordered it. Good luck finding one.

The Amazon one I ordered was the Chrysler brand, so I sent it back. I am still trying to find the Dorman one.

I wanted to thank those who took the time to diagnose and describe the fix. I took care of mine this morning. Our van was just over 36k and I will say that I wish I had done this under warranty because it is a pain (but doable). A few notes the actuator is the one which is not immediately visible:

I made the mistake of first removing the actuator which is more visible. Also here is a photo of the vent I removed, and a tiny socket is a must:

My hands are too big to get at the blind actuator screw but I think I could do it if I removed the blower motor assembly or the plastic lower trim (knee) panel.
Removing the knee panel would provide plenty of room to access the actuator but I'm not sure how to unattach the drivers side of it.
Has anyone tried either of these?

On my 2018, I initially removed more than I needed to, but it ended up making easier by giving me more room. I removed the plastic panel on the passenger side at the passenger's left foot (the one that the light in the picture directly above your post is pointing at). That panel is held in by three retainer clips that engage in rectangular slots and the panel will pull directly out by pulling it towards the right side of the car. That should give you additional access to come in from the side of the actuator.

Thanks. I'll try that.

Yes, mine is back as well. I purchased and self installed the dealer replacement part. I am almost certain it is a driver problem, not the actuator. I am just going to let it oscillate until failure. It is out of warranty and not a safety issue, so I expect it will receive NO ATTENTION by FCA Chrysler, either to fix the problem on existing owner's cars or on the newer vehicles being produced. It appears as if they just do not care.

 

[drocketman]

It looks to me like the only fix for the problem of re-occurrence is for some resourceful person to make a damping circuit to place on the actuator leads going into the actuator to de-tune the oscillation. This is assuming that there will be no fix offered by FCA. I could do it if I had the time.

I think there will be close to zero chance for a real fix by FCA. If you come up with this real fix please document and share!

I let mine oscillate for a couple of years before I finally replaced it myself earlier this month with an aftermarket actuator. I knew right away what the sound was in a very general sense when I first heard it, but I didn't have the time to address it as I was just starting a new job. That new job also kept me out of this forum for quite a while so I hadn't read about the fix until just recently. Even though I was still under warranty, I was reluctant to let the dealer dig deep into the dash (if that's what it was going to take) lest things not go back togerther properly. I do have an extended warranty (despite my knowledge that having one is almost always a bad financial decision) and I think it would likely be covered, but I still didn't want to lose the car for the time it would be at the dealer. So, even knowing that the job wasn't going to be all that complicated for the dealer, I elected to do it myself, because I assessed that the "cost" to me would actually be lower if I did it myself. The one piece of data I can add is that it can oscillate for quite some time without actually failing - maybe virtually indefinitely.

I still have not been able to find the Dorman part in stock. Does anyone know where to find it?

Same with me. I bought this one:

no idea what how durable it is, so far I've only had it installed for about a month, but it does work so far

If you can't find the Dorman part, Four Seasons/Murray 73281 is compatible and should also have acceptable build quality.

Are the screws that hold the actuator Phillips or 5.5mm socket?

A 5.5mm or 7/32 inch socket will work.

Only need a 7mm socket to remove the two screws for the floor HVAC duct to get it out of the way, and a 5.5mm socket to remove the two servo screws.

Thanks.
