I have no heat coming from the front or rear. I have flushed the entire cooling system, i have blown out both heater cores with water and air, both ways forward and reverse. i replaced the water pump, the thermostat. previously i had replaced the front blend door for no heat in the front about 2 months ago and everything worked great until 2 weeks ago. I even packed cardboard in front of 3/4 of the radiator, now when i drive it tries to get lukewarm but at idle it goes cold immediately. the top radiator hose doesn't get hot which tells me the thermostat is stuck open. i just replaced bit 2 days ago. i thought about changing it out again, but i am getting frustrated. i have been a professional master technician for 40 years, i can't even read ECT with my Snap On Modis. all i can seem to find is cylinder head temperature and that value is measured in volts and it seems to be within specs.
