2017 Tahoe have had issues with liftgate not finding position and just going up and down without stopping at the top. Module has been replaced, struts and lock assembly. Been working on vehicles for 30 years and it seems to me the door can’t find the stopping point. GM dealer thinks it’s the harness, I’m curious if the position switch in the header is the issue. TIA!

I just want to confirm that you replaced the two support struts and located them on their proper sides (the 2 struts are different). If the struts have deteriorated to the point where whey will not support the weight of the tailgate, it will come back down when you try to raise it.
