I turned on the heat this morning and the air blew only through the front dash vents. I directed the flow to the windshields but nothing happened. I used all types of settings but the air blew only through the front dash vents. I can not defrost my windshields; needless to say what is going to happen when it snows during winter. I searched but could not come accross a similar thread. What can I do to direct the air flow the way it is supposed to be. I did get either warm, hot, or cold air based on the settings but the air seemed to go only in one direction. Thanks.
