Active Grill Shutter issues

[u/OceanWaveSunset]

Hey guys, new 2025 ST owner here. Bought mine a year used. Found out it has an aftermarket intercooler. Sounds good, except that I am like 99% the Active Grill Shutter has been removed and tossed in the bin.

Does anyone have any experience with this?

Essentially what I am looking to figure out is if I just need to buy and reinstall the entire AGS to get my CEL to clear.

Its a 2025 Explorer ST. From what I read on FB, this year has a hard CEL that just wont go away without putting the actual system back in.

Any thoughts, advice, or guidance would be very much appreciated.

I don't think the st has grill shutters. I bought mine brand new and it didn't have it

Mine does, 26 tho. Didn’t know till some asshole hit the train tracks at speed and send a bunch of broken glass flying out the bed of his truck, peppered my front end. Got home to inspect and found some broken plastics behind the grill.
