Long story, car sat for awhile in my garage. Mice got in my cowl and made nest....made sh*t....made a complete mess. Wondering if this has happened to anyone and how did you clean it? When i turn the fan on the inside smells TERRIBLE! Im not sure of the cowl to heater core ducting, am i able to just spray the cowl down with cleaner and have it drain out the bottom side of the car? The last thing i want is all that stuff in the heater. Any help would be greatly appreciated!
