If you are absolutely, positively sure that your coolant level is not low......then your heater core could be plugged. Or the control that turns the coolant flow on/off to the heater isn't working. Make sure the control is working, the flush the radiator. Should cure the problem.
thermostat is stuck With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
because its not working proper.
bad heater core, heater hose blockage, low coolant, bad heater valve, bad control head. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
Fuse- Blower Motor- Wiring- Selector switch fail- i8f you still have heat to the heater core, if the heater core is cold, and the mottr is still hot... change the thermostat
It's not normal.It is possible that the heater in the humidifier is not working, resulting in a cold airflow delivered to the mask, which might cause you to shiver.If the heater is working and you still find the airflow too cold, you may need to use a heated tube to ensure warm air delivered at the mask.
Only the fan is working, there is no gas burning (gas heater) or the electric heating element is not working(electric heater)Answeris it electric gas or oil Its gas.
Most likely your pilot light is out
Assuming the blower fan is working but it blows cold air, it could be,Faulty temp blend door actuator.Plugged up heater core.Faulty thermostat,Low coolant level,
it wont blow heat itll blow cold air
Low coolant? Bad thermostat? Heater core plugged,restricted or airbound? Heater control cable or valve not working?
The #1 cause of cold air from the heater when the car is stopped, or the engine is idling, low engine coolant levels.
It sounds like your switch from hot to cold is stuck on cold
