300te 1989 heater motor stopped working...

[Eliot]

I live in New York...my 1989 300te heater motor just died (or at least I believe it to be dead). I will do the work myself, but I want to have the parts on-board and ready to use. Besides a new motor, what other parts should I have ready? Where is a good place to get a new motor (providing I can save the cages)? Can the motor usually be returned if I don't need it? I could use the Yellow pages, but I don't know what to ask / look for....thus I turn to on-line parts suppliers.
