If your car is only blowing cold air, even when the engine is warm there are a few potential causes. The heat that comes through the heaters is generated by the coolant being passed through a heater matrix behind the dashboard. This is like a mini radiator, and the blower blows air over the matrix, and into the car. If it's not blowing hot air check the following: Coolant/Air lock Is the coolant at the correct level? Low coolant may prevent it from circulating through the heater matrix? Is there an air lock? Follow the bleeding process outlined above, ensuring the heater controls are set to maximum heat. Heater Control Valve When you set the heaters to hot, air being passed over the heater matrix should be ducted into the cabin. If it isn't it could be that the heater control valve is not working and needs replacing, or on older cars a physical flap which alters the path of the air could be broken, or disconnected from the controls. Thermostat If the thermostat is jammed open causing the car to overcool, there may not be sufficient temperature in the coolant to provide sufficient hot air. Test, or replace the thermostat, as mentioned above, if you suspect this to be the cause. Blockage There are some very thin tubes in the heater matrix, and if it becomes blocked the coolant may circulate as normal around the engine, but not reach the matrix. The cure is to flush the system with a hose, or by blowing compressed air through the matrix if you can access it. #carheater, #carblower #carrepair
