What's going on and off? The blower motor, or the HVAC controls?

Seems like the blower motor is stopping and not delivering the heat- just got the trouble codes: a047- low refridgerant and pd39- rear long term fuel trim??
Good point cabbage- i jumped to the electronics when it may just be a bad blower motor- thanks for the sugestion
