Can you take apart the rear blower motor case? Not for heater core
replacement, but to expose the innards of the motor.  I have one that seems
to work fine but squeals a little bit. I have it apart now for a valve
replacement and I'm trying to figure out how to get to all of the
bearings/friction points to apply a little grease. It looks like should
come apart in two halves, but I can't seem to do it without breaking it.
