Heat in my Jeep works fine when on low but when I turn the fan any higher just blows cold air. Air comes out from defrost,dash,floor vents like it should too. Thermostat changed.
I should add that the upper heater core hose blew out once. After I changed it it seemed to have heat on all fan settings then. Now back to only feeling heat on low fan setting.
