No heat,blower is fine,all vents work and engine temp.is normal.no water leaking from heater core.windows don`t fog up.
Had same problem. Back flush your heater core. Disconnect both lines, going into heater core, get short piece of hose and put it on the pressure side. Take garden hose and spray into return side. do for few minutes. hook lines back up should be good. My heat still works.
The valve that allows the hot water into the heater core is not opening. most likely electronic issue. also check all vacuum and electric lines.
