ROCK4200,
At the fan motor connector, check for 13VDC from the red to white wire and 8-13VDC from the white to yellow wire.
If the voltage is correct then the fan motor is bad.
If the voltage is wrong then unplug the J-2 connector on the main control board. Check for 13VDC between pins J2-3 and J2-8 8-13VDC between pins J2-3 and J2-4.
If the voltage is wrong replace the main control board.
If the voltage is correct then the problem is a bad wiring harness.
If there is less than 1 K ohm between white to red or white to yellow wires on the evaporator fan motor, the motor is bad and has to be replaced together with the main control board.
- The part number for the main control board is
AP3950129
- The part number for the evaporator fan motor&thermistor assembly is
AP3191003
