Great news! Glad someone else benefitted from this post.
I also worked forward and found the much heavier guage splice. It, being
so thick, was ok. I didn't work backward though, so I'll have to reopen that
area and see if I have the same issue with the black/white striped wire.
So, onto the next problem... my passenger side "automatic" sliding door
doesn't work. Similar kind of symptom. Doesn't work from ANY of the buttons. Hey, maybe it's the black/white striped wire! That would be sweet!
I also heard that there is some kind of recall for the door, so I gotta check
with the dealer on that.
Do me a favor and post any news on your Venture here. We can all share
in the misery and also share in the repairs!!
