Thermostat is stuck open Thermostat is stuck open
When a vehicle is idling, the engine may not produce enough heat to warm the coolant effectively, leading to cold air from the heater. In contrast, while driving, the engine works harder and generates more heat, allowing the heater to blow warm air. The engine temperature can rise while idling due to reduced airflow through the radiator and less coolant circulation, while driving increases airflow and coolant flow, helping to cool the engine.
youre driving a ford!
AnswerYup, in most cases. Check the thermostat.
It is more than likely a thermostat
sounds like a bad thermostat even though it is replaced
I'd check the coolant level first, then the thermostat.
Poor circulation probably due to a restricted (plugged up) heater core.
Your thermostat is stuck open. Buy a new one they are usually really cheap and you can usually repair it yourself. They are easy to get to even in compact engine space.
I own a 1997 Ford Contour and there was a recall a few years ago on the heater blower and resistor. Check out the recalls on the car.
The vehicle does not have any airflow across either the engine or the radiator to cool things down like occurs when driving, if at an idle. This, coupled with a diminished flow of coolant through the engine at idle speed creates undissipated heat.
BMW have an auxilery water pump that circulate coolent into the heater core at low engine speeds check the operation of this pump and solinoids.
Poor circulation through the heater core. Probably a semi-plugged heater core or a faulty thermostat (assuming the coolant level is full).
