That is strange to happen at the same time. You either have a bad control board or evap fan motor. First try resetting the unit by unplugging it for 5 mins. See if that works. IF not, At the evaporator fan connector, check for 13VDC from the red to white wire and 8-13VDC from the white to yellow wire. Make sure the unit is warm enough that the thermostat is calling for the unit to cool/run. If you have proper voltage then you have a bad fan motor. If not the proper voltage then as long as your wires are not damaged you have a bad control board. Take a look at the control board. There are 2 large resistors. IF either of these resistors look damaged as in melted or burnt/discolored then you will need to replace the board and the evap fan motor. Let me know if you need any further help. Attached is link for the fan motor.
