I had the same issue in that I replaced the actuator on the driver's side of my 2012 Edge SEL. Afterwards nothing changed - the linkage didn't move. I cycled a few times through the hottest setting and max a/c - worked as expected on the passenger side but no movement on the driver's. Eventually gave the linkage arm a gentle push with my finger as the system was calling for max a/c and it moved a little. After that everything worked correctly - just needed a little persuasion first time. I remember someone asking for the part number and a supplier in Toronto. I didn't have much luck with that and had to get the part from a Ford dealer. Part 7T4Z-19E616-B. The Ford parts guy asked if the part was with or without humidity sensor. I had no clue so he had to use my VIN. Looking at the old part inside I'd say it was without sensor. Price in Toronto? $97
