More likely you have run out of coolant. The coolant heats up as it circulate throughout the engine. The hot coolant produces the heat as it passes through the heater radiator matrix, where the fan blows off the hot air.
Check you dont have a coolant leak, and dont let it run out if you are driving it or you will bugger the engine.
sounds like your hub bearing assy.is going bad
my heater switch on my vauxhall frontera as just stopped working but we can feel slightly heating coming through
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
Behind the glove box, under the dash.
You have run out of coolant, or the heater matrix is blocked.
Low coolant and a clogged heater core are possibilities.
faulty control valve on heater or air in the lines
If your heater is a heat pump , then yes.
If you feel no air blowing at all (when you are not moving) then your fan is not blowing. If it is blowing air, and it is cold, when the heater is on, then most probably your heater core is leaking, or is clogged. These are easily replaceable and go bad all the time in older cars.
You may need to replace your Thermostat or your Heater Core.
Could be a bad thermostat or heater core
One reason your home electric heater is blowing cold air is the heating elements are burned out. A bad thermostat may also be the problem.
did you check the heater core because my truck did that and that was what was wrong
Isn't a heater supposed to blow warm air?
No one knows if:The heater is NOT blowing - or blowing on high speed only, or... The heater IS blowing, but the air is NOT hotEither way, the "Related Questions" below will get you started
Which part isn't working? Is it blowing air but it stays cold, is it not blowing at all or is it just blowing to the defroster?
Did you chech the fuse?
Could be a Faulty relay.
The heater core is leaking coolant.
Heater blower motor is defective and locked up, or possible short in the wiring.
That means either you have air in your heater core or your heater core is being bypassed
it is a heater. heat. it blows heat. warm air
Sounds like heater core is leaking, replace heater core or bypass
check for a blown fuse that says heater or blower motor
