Right rear vent window won't close on 2007 Chrysler Town & Country

How do I fix the passenger side rear vent window on my 2007 Town & Country? It will not close.

What you haven't told us is it a powered vent window or a manual one. If it is powered then it could be a bad motor, switch or wiring. If it is manual no clue.
It's a powered vent window. I'll have to check for power. Thanks.
