[W126 Coupe] AC Blower not working

[Steve Nervig]

I'm suspecting possibly the brushes have worn enough and/or the bearing is worn enough that the fan motor was drawing too much current to turn the fan before, so the fuses blew. The motor is now "stuck." If you could get to the fan and use a little ATF on the bearing and get it spinning, you might be able to test this theory.
