Beginning two days ago the lower grill shutters on my ‘21 AGT have been stuck in the closed position, though I can hear the solenoid trying to move them. There is an intermittent click as the solenoid clutch(?) gives out/resets. I initially assumed this was due to snow/ice buildup, but any should be melted at this point. Perhaps damage was done earlier. Anyone else experience this? I have a tech appt on Monday and will have it evaluated. Assuming at this point it may need a trip to the shop to fix.
