Why my Honda Odessey mini van driver side electric sliding door will not close?

reset the doors remove the negative on the battery for at least 5-10 minutes but make sure there is nothing in the top and bottom track that should fix it

Another solution: You can also try holing out the handle and not releasing it back in. This can allow the door to close. If it doesn't latch you can lean into it to latch it. This worked on my 2006 Honda minivan.

Sounds like a roller is broken. They have a hard time getting around the final bend in the channel when broken.
