Our 2013 Fusion didn't blow cold air either. Turns out the car had a short in the wiring harness and shorted out the fuse box. Had to have the box replaced and the short found and fixed. A/C blows cold now.
Picked up our car at 4:00 pm today. Fix was downloaded and the headlamps were replaced.They also washed it and filled the tank (I dropped it off with less then a 1/4 tank). Happy to be back driving it again.
Take care....Ed
