My Escort has NO heat!..UNLESS the fan motor is on.NONE!It is VERY annoying to have to turn the fan on..THEN the car becomes an oven..THEN off and it becomes a fridge..
Engine operating temperature is fine,coolant,circulation.There is plenty of heat at the heater core..and plenty when the fan is turned on.
This car has a/c and it works perfect..
All the controls APPEAR to work properly.The outside air vents are not plugged..I'dno..can't find the answer..I get the feeling that there is some problem with the vent control doors WHEN the heater selection is used..
What does work is to leave the fan on AND adjust the temperature control..is this the ONLY way?
I'm starting to miss my old car..I could leave the fan OFF and the control set to heater..and the temperature control wherever..sure the car would cool down when I stopped..and warm up as I drove..BUT at least there was a consistent point where I didn't have to fiddle with the fan.
