Considering that all the openings supporting airflow are jammed packed, no wonder.It seems to be a lot less efficient with all the snow around.
An alternative I used before after super snowy days was just a car wash. They keep water reasonably warm in cold days so all of this grime will go away with water pressure and warmth. Most places will allow you a second run (or more) if the car is not reasonably clean. Garage would be best, though, especially if you have above-freezing temperatures in there.Then use a hair blow drier
