Driver-side windshield does not defrost for a long time while the right side (passenger side) defrosts properly.
There is inadequate airflow in the front defrosters. It barely defrosts my windshield and makes it very hard to see. The vents just don't seem to produce enough air to defrost the windshield. The first incident happened in the late spring on a chilly wet day. It was ok during the warm summer weather.
