I checked for the 13vdc at the board and replaced the fan but it still didn’t work. I checked for the 13vdc again and it only showed 7 vdc. Is it the board? It is not in the wiring is it? Isn’t there a way to check the motor with a 9volt battery and how would I do it at the board to check the wiring to the motor first before I replace the main board? I have the tech sheet. Is there any information or video about this problem?

Hello
The SYEF is an evaporator fan motor curcuit error . If you replaced the evaporator fan motor your PCBA board is defective replace it .We see the many times with this board. That board controls the motor. See diagnostics link below. Matt Ace technician
