The rear window defrost/defog heater grid.
That means either you have air in your heater core or your heater core is being bypassed
you may have your switch on your heater control set to recirculate the inside air. it should be set for outside air recirculation
Check behind the heat control panel to be sure that the vacuum hoses are all securely plugged into the control switch. As a safety measure on all cars, if you lose vacuum altogether, the default position for air direction is on defrost, so you can always see out of the windshield. Jake McCahn
I had the same thing happen on a 2000 Stratus and it ended up being a bad heater blower control switch. I replaced the unit and everything worked great.Answeri belive this would be a bad blower motor resistor check that because you car has two resistors for the heater one which controls low med and med hi and the other control only high for safety reasons basically so if you need to defrost your not left with out heat
