2006 altima blower motor problems

I got a mouse nest in the blower motor area, I pulled out the in cabin air filter out and got most of it out, but wanted to remove the blower motor to get the rest of it. Got it opened up enough to get the rest of the debris out of it. Trying to take out the complete blower assembly I unbolted it from the intake and took it loose from the duct area, Now i can get it back in place to bolt it back up. Does anybody know of a diagram, how to instructions or you tube video on the web how to get this back together. Now i'm thinking i might have to dismantle the entire dash but i can't find any instructions for that either.
I have a Haynes manual but i doesn't tell me much about my year. Thanks for any help you can give me, Randy
