2018 Yukon Rear Passenger Door Randomly Won't Open

[MJCossitt]

Child Safety Lock is turned off.

My passenger side rear door will randomly act as if the child lock is on. It won't open from inside but can from the outside. It just does this at random. I thought I had figured out that if I turn the child lock on before shutting it off, then the next time I go somewhere I can turn it back off and the door will open again. This was true up until the past few days. Now it won't open from inside at all.

My passenger side window also will not roll down (started about two weeks ago). Not sure if these are related with some sort of electrical issue.

I cannot personally assist you with your issue, as I'm not sure how the 2018 door systems are wired, but other members of this Forum much more knowledgeable than me in this area will chime in.
