Want this question answered?
hello Can you tell me why the heater on my 2002 toyota yaris isnt working? Ive changed the thermostat,flushed out the radiator and also the heater matrix behind the dashboard is getting red hot as well
Low coolant? Bad thermostat? Heater core plugged or airbound? Heat control cable not working?
System airbound and needs to be purged
MY CAR WAS DOING THE SAME THING NO HOT AIR COMING OUT OF THE HEATER I CHANGED THE THERMOSTAT. IT WASNT THE THERMOSTAT. I GOT TO CHECKING AND THE SEAL IN THE WATER PUMP WAS BAD. I REPLACED THE WATER PUMP AND IT WORKS FINE NOW.
Yes it will stop heating up...........
Have you flushed the heater core?
Your thermostat is stuck open.
Yes, A bad thermostat can keep the hot coolant from reaching the heater core... also, low coolant levels or a clogged heater core can make your heat stop working.
Low coolant? Thermostat not opening? Control cable not working? Plugged heater core? Heater core "airbound"? Low coolant? Thermostat not opening? Control cable not working? Plugged heater core? Heater core "airbound"?
Heater core changed three years ago,I changed Thermostat Heater still blows cool air.
Low coolant? Bad thermostat? Heater core plugged, restricted, or airbound? Temperature control cable not working?
First check the water level. Low level will not get to the heater core. Change the thermostat. If you recently changed the thermostat, bleed the coolant system.
