Randomly had a clicking noise (I believe it was as A/C is turned on/off) and it was accompanied by the driver side blowing cold air and the passenger side blowing hot air. Looked up a YouTube video and found that it’s typically one of the two actuators behind the glove box. So I took out my glove box, looked in there and could see the problem clearly. It was a worn out A/C actuator which couldn’t keep up with the rotation, resulting in that clicking sound whenever you mess with the A/C. Just make sure you get the right part, I used the (Duralast HVAC blend door actuator) but I bought 2 actuators and replaced both of the ones I could see just in case. One of them is very easy to replace, the other one is back deeper and some of the small screws are hard to get out. You’ll definitely need to position some sort of light upwards from the floor to help see where you’re installing this thing. I accidentally broke off the red clip that attaches to the actuator but it still works for me. It’s been almost 3 years now and I have not heard that clicking sound since replacing it. (I’ve heard other sounds since then but that’s another story)

Apparently this is a known Dodge issue and I wish I knew before buying into the family. Approximately 10 seconds after shutting off the car, a low clanking sound can be heard for roughly 30-40secs.

I've been told by Dodge repair techs that this is a common occurrence, but no recall has been put in place to address the issue. I was informed that the "actuator repair" took over 11 hours (which I honestly don't believe) to repair and is extremely costly if performed at the dealership (as are most things).
