Volt not able to charge due to charger issue

Heavy snow/rain storm here in the Northeast has caused my 2017 OEM charger to stop working. Once plugged, the charger clicks in place but no green light on the dash or beep. The charger unit itself shows a green light so it's receiving power from the outlet. I've tried a coworkers charger and it works so it's not the car that's the issue. I've tried cleaning out the holes in the charger by blowing in to them and clearing it with a small screw driver. Tried turning the car on and off with no luck. Any other ideas before I go to the dealership? Thanks.
