A/C front and rear blow cold air. The front randomly stops. What could be issue?

What is your question?

We just bought a used 2014 Expedition XLT with auto climate control. The AC works and blows cold in front and rear. The front just started to randomly cut off during idle or driving and at times not even come on when cranking. I have read multiple forums about that shouldn’t be the blower motor. What could I look at to fix solution without going to a shop?

What makes this problem better or worse?

Nothing

How long has your 2014 Ford Expedition had this problem?
