The heat on my drivers side is blowing cold air while the passenger side is working just fine. On the windshield it seems fine but the floor and dashboard are both blowing cold air on the drivers side but the passenger side is fine. Any Ideas for me?
You have a plugged heater core. The distribution box is split to each side. The core is only getting hot on the half that feeds the passenger side. Try flushing the heater core both ways it may work if not heater core time.
