Jeff. At this point the best thing to do would be to install a new motor.
Even if you could get the old one freed up after you pull the dash chances
are it would work for a short time and then freeze up again.  A new one
should last for many years and getting inside the box will allow you to
clean out the inside from mice trash and redo all of your foam flaps.  It
is just time.  Let me know if I can help you out with parts or advice.
