Eyes burning from A.C being on

Only when A.C is on eyes, nose, and throat burns within seconds, doesn’t happen when just the air is on or heat, recently brought it to dealer and they changed cabin filter saying a rodent made a nest and the urine was what caused the eye burn, they said it was fine and their eyes weren’t burning any more, well a 2017 chevy 3500 with 3700 miles and it’s still doing it, originally thought it was a leak from coolant or frown but they probably didn’t check, anyone have an idea

Not sure what (frown) means but you need a detail shop or you could spray Lysol in the cowling in front of windshield with the fresh air blowing on full.
