Sorry it took me a minute to see this thread. As far as I know, there's no override or anything for the window, which sucks! best I can advise is pull the interior panel(s) in the rear and force it up. The motor's broken already anyway, so you don't have to worry about breaking it more. Also, for a replacement, check out
www.hondaautomotiveparts.com ... they can overnight parts and will give you the best price on replacement parts like that.
