Rear vent windows will not close 2006 Montana fuse checked out ok both windows
Did you check the window relay, I think it located in the fuse box...
Yes relay was also checked
I had exactly this same problem, and after my "colorful metaphores" I found that the wire that supplies power to the windows was broken. This wire is in the harness that runs along side of the Passenger seat. It sits in a through under the carpet. The sand and water that seep in there was a great sandpaper and wore thru the insulation and the wire. I only where it was by pulling the fuse, installing a small wire into one side of the fuse holder, and putting a signal generator on the wire and following the signal until I lost it between the Passenger seat and the roof post. Pulled up the carpet, found the break, cut out the bad wire and soldered in a new piece...and the windows have worked ever since.
