2014 Dodge Durango Citadel.
Our rear tailgate was falling down. Unable to stay up. But still opened and retracted.

Changed out the tailgate assist strut. (passenger side) as well driver side power unit. Unfortunately it will open but immediately sinks and smacks my wife on the head.
I read a few posts on facebook identifying you may have to put the vehicle into a "learning mode"or something to that extent.

I have obd jscan and mx+. I found a section for tailgate in the tool but couldn't find any "learning" or reset function.

Any advisement?

yes bought both units the same time because, yes, I read the strut on the passenger side was key. I actually bought the struts off amazon and came with 2. tried both. power motor I got from the dealership.

SO to validate, no programming of any sort is required?

See what Chase300 comes back with, but when I look at this manual link, it only mentions to test strut for proper operation after the power liftgate support (motorized one) is replaced.

But.... I'd say right here is your problem:

There are a TON of inaccurately linked and incorrect aftermarket parts on Amazon! If it came with two liftgate support rods (gas prop struts), dead ringer they are not the right parts. Either they don't have enough pressure, aren't the right length, or both. As both Tin Foil Hat and Chase300 pointed out, bum/wrong assist strut.

At the minimum, find out what liftgate support rod part number is allotted for your VIN, and order it from the dealer or online OEM parts source. Just a glance, it looks like there are two different passenger side support rod part numbers, likely one for with the power liftgate, and a different one for without. That's why checking to see which is matched to your VIN.

Yes I don't disagree with your statements on amazon auto parts and inaccuracy's . I'm just attempting to narrow down the problem between the motorized strut, potential programming (if required or not), and potential new defective items and wrong items. I would say if the programming is not a factor then yes the amazon pass strut replacement is more than probable the wrong item.

Apparently there is a power liftgate module that would need a relearn process if you replace the motor lift. You have to do that with a scantool.

Thats what my review found as well. information tad minimal. though I have not reviewed the links supplied above yet.
But as stated above as well I didn't see a function in obj scan tool under tailgate.

So yes I'm wondering IF its a programming issue or a wrong part. But I went ahead an ordered a over priced OEM pass side unit.

If anyone reading may have information on a mobile app scan tool that can facilitate the programming that would be exceptional.

AND YES.....
It was the passenger side strut. I purchased a OEM unit and obviously it was different. It does sink an inch when it gets to the top. BUT compared to it falling down on your head that a significant improvement.
