Q: How much to flush out system cause car has no heat

asked by on

Car has no heat have tried heater cooler ect but no heat

My car has 30000 miles.
My car has an automatic transmission.

The heater core being plugged is not the most common cause for this vehicle to not give heat out of the vents. If you move controls to heat and do not notice a temperature change when turned hotter the most common cause of this issue is the temperature blend door actuator does not move the blend door toward heat. You will need to check heater hoses to see if both are hot indicating coolant is flowing through the heater code and the problem is in blender door movement.
