Rear vent windows not operating properly is a common problem with Honda Odesseys. The solution is to replace the window motors.

Happens intermittently. If they won't open/close, I try again at a later time and usually the problem is gone. i have had them stuck in open position when a rain storm came through, but the inside didn't get too wet so I really dion't worry about it. Hopefully they will never get permanently stuck in the open position!
Rear windows were never good on my 2002 Ody. Failed while under warranty and then they worked, quit, worked and are now pretty dead. Just confirming the fact that these windows are a Honda Bust!
This is a well-known problem with the Odyssey. It happened to me, and I found detailed instructions on repairing the problem on the internet (http://www.odytalk.com/showthread.php?29-How-to-Fix-your-Rear-Vent-Window-Motors&s=b2feb4ba865d367c997ac540399c6788&p=36#post36). I have yet to complete the repair; they've been completely inoperable for four years now... maybe this weekend I'll get to it. ;)
