So I just did a little walk around my 2014 Ford Fusion Hybrid SE 88k. One thing that I've kind of always noticed is the active grill shutters (AGS) (the main ones behind the fascia) always seem to be shut. I decided to a test to see if I can get them to open. I had been driving around prior so the engine was already fairly warmed up. The temperature outside was 90 degrees. With the car parked I turn the climate control to MAX A/C wait a min and check, shutters closed. I floor the pedal for about 20 sec. with ac still on, still closed. I feel both of these things should have triggered the system to open the shutters. I am very concerned that the AGS system has a fault or something is blocking them somehow. Theres another set of AGS in the lower grill area of the car that have seen better days but this set has a way to chalk them open or closed. The upper/main ones dont seem to have this. I am worried that: fans are working to hard to cool the engine and a/c system, also that the engine isnt getting enough fresh cool air that it should. Both of which hurt MPG. I hear of ford focus st owners removing this system and noticing more steady performance. But on the other hand I hear of Cmax owners installing additional shutters to extend MPG. Please Advise
