Low coolant? Bad thermostat? Heater core plugged or airbound? Heat control cable not working?
The water is not circulating through the heater core or you have a control problem. If the heater is putting out heat then it is probably a control problem. If no heat then - water pump out, low on coolant, or maybe the therostat is stuck open.
I would suggest replacing it.
the heater control has a thermostat for the heater only. that thermostat needs replacing
It does not have a heater control valve.It does not have a heater control valve.
Usually at the firewall either passenger side or middle follow the heater hoses
I had this problem once with a different vehicle. You may check the heater control. That may be the problem. Hope this helps.
Passenger side, near the firewall inside the car.
most of the time it the heater control unit on the motor not the heater core had same problem
under the dash right hand side.
