other Heater Box Fan Replacement

[paulram]

In my quest to track down wires, I get further and further into projects.  This time since I was replacing hoses while waiting for the new gauge for the cluster to arrive,  I started to replace the hoses to the heater core.  And since I had no fan, I had to see if the wiring was hooked up. And so it continues.  No cluster, no heater box, and no console in the car...If you give a mouse a cookie....

 

Anyway the wiring looks fine but the fan is cracked, missing some internal pieces and doesn't spin easily.  Do I replace the fan only or the whole assembly.  I have yet to crack the box open as in the article posted on the site.  Figured I'd ask first, crack later.

Motors are available from Blunttech for $80 but fan blades are harder to get I think.

It's a bit hard to evaluate a heater case with a single photo. The "cage" surrounding the fan blade was never particularly robust. Forty years of drying out left the cages even more brittle. Yours appeared to have taken a shot: maybe a ham-fisted mechanic/owner trying to replace the hoses or the heater control valve. Are there cracks, chips, fissures, etc. in the rest of the case? If so, I would probably look around for a new heater case, bearing in mind that many are in this sort of perilous state at this point.
