I hit a coyote and my grille shutter was shattered to pieces. I still have the actuator and it works, but no grill. I found a couple people saying you can wire a relay to trick the computer to think the grill is opening and closing as long as you still have a functional actuator. I got a 4 pin relay. Pin 30 = battery + Pin 85 = Chassis ground Pin 86 = positive ignition 12v power Pin 87 = grey/black wire at the shutter actuator I still get a CEL one from the FPCM, one from ECM Did I wire the relay wrong?
Change the fuel pump control module w one from a non eco cruze. Get a used one and it latterly plug and play. It's in trunk right side. Thank me later.
