Not sure how old your dad's vehicle is, however, inspect the seal around the door. Look for any damage to the seal, any dirt, tears, rips or general wear. It may be time to replace the seal, they eventually degrade over time and need replaced. The seals are one of the most overlooked items on a vehicle; the same as the refrigerator door seal in your kitchen.
Another thing you can check; try to lift up on the door while it is open, sometimes the door hinges start to weaken and begin to sag some creating a small gap between the seal and the upper door jam.
Good Luck
