Edit: I saw this before your PM - I did respond to it.
If the motor is indeed seized like your PM mentioned, ask again here - I don't know if I can answer that, but some TLC may revive it if it isn't completely cooked.

here are my notes from a few years ago:
Remove 2 tube clamps (ducts) (as Gerry mentioned)
Remove power connector (grab white part and pull firmly)
Remove blower – wiggle from bottom removable rubber boot.
Undo top screw
Undo 4 clamps
Remove plenum and pry squirrel cage fan from body with screw driver (twist)
Remove connector from spade connectors
Push motor from plastic body
Clean
Lube felts (3)
Re-assemble

I hope this helps.
