Keep in mind that if you select "windshield / defrost" mode, or any other mode that includes the windshield defroster air, then the AC Compressor may come on to dehumidify the air, to avoid fogging the windshield.
Most Ford locations are supposed to be getting EV charging stations installed. Would suggest you talk with the Facility / Building Manager about that, and see if they can run an extension cord to your car to use the 120V charger in the interim.
