Did you take a voltage test to that fan motor at the fan motor electrical connector?
Here's the tech. data sheet:

SY EF--->Evaporator Fan Circuit
DO--->Diagnostic Mode TEST 15=Evaporator Fan
If it does not run, use a
multimeter to check the voltage at the evaporator fan motor electrical connector and see if your getting 12 volts DC.
To volt test it: Check for 12 Volts DC to the fan between red and brown wires. If it checks ok
WITH a CONSTANT 12 Volts DC and the fan motor is SPINNING UP for a second at a time, then replace the Evaporator fan motor.
Here's another thread I explain about it too:
I’m trying to find out how to access the evaporator fan and control board (for the evaporator fan) for a kenmore model 253.70319211. Can anyone help with this simple question, I would appreciate it?
