well, looks like the blower on the back of this circa 1983 clayton 7.1 furnace is about dead. and it's 16 degrees outside. anyone have any ideas of how to go about finding a replacement. i've called around to HVAC and some woodstove places in the area (zip: 21078) but no luck. i've thought about a motor rebuild, but figure that could take several days, which i'd rather avoid. thanks.
