Heater blower motor replacement

Any fast and easy way to replace the heater blower motor on a 65 fastback with factory air.

No fast and easy way. Factory air is not related to the heater blower motor. You have to drain the coolant, pull the heater box, then pull the motor. While the heater box is out, it's a good time to replace the heater core and freshen the seals on the box.

If the heater hoses are old and suspect, just cut them close to the firewall to save some time and energy.

That's what I thought. Thanks
