First and foremost, welcome from Utah!!! Well, I know when they don't want to open correctly it's usually the dampening shock gone bad. The little one on the passenger side. The good thing is, they are a very cheap, and easy fix. As for it not wanting to close correctly, that could be something else possibly? Does it open, and close right if you kind of help it a little bit???2016 Jeep Cherokee tail gate will only open a 1/3 of the way then close and when open will close 1/3 ok the way then open all the way. What is the problem.
Today I had a chance to prove this works for real.Try this Youtube video:F50 in the PDC seems to be the trick. Look at F50 and make sure it has not opened the circuit.
Determine if Recall R27 applies to your Jeep and has been done if required.
