If the heater in a Daewoo Leganza does not work well and you have already had the antifreeze lines flushed with new antifreeze and a new thermostat what else can you do?
It could be a partially blocked heater core, a faulty heater valve that allows the coolant through the heater core or it could be a faulty water pump.
You have antifreeze leaking only when car is running It is dripping down underneath the passenger side next to trasmission It is pure coolant You changed thermostat?
I would check the hoses leading into your radiator, and also the overflow for antifreeze. If that is not the problem, it could be your heater core. Your heater core might be leaking, you might have a hose leaking
Where is the heater core temperature thermostat?
The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
How does antifreeze flow through an engine?
The water pump forces the coolant to move through the water jackets after the thermostat is open to the manufacturer to the temp. spec. After the thermostat is open the coolant flows through the radiator to help control the cooling. When you turn on the heater the hot water flows through the heater core and back in the return line to the engin block.
Would straight antifreeze make heater blow cold air?

Why would the heater in a '94 Ford Escort not get very warm could it be a direct problem of the thermostat?
Yes. If the thermostat is not staying closed long enough for the engine to warm up adequately, you will not get heated coolant into the heater core and the heater will not blow warm air. Change the thermostat for a 195 and you should get plenty of heat. It could also be as simple as not having enough coolant. worst case senerio would be a bad heater core.
What causes a night heater to blow cold air?

No heat in a 1991 Chrysler LeBaron good blower?
If the blower is good then the problem is coolant. Something is stopping the warm coolant from the engine from reaching the heater core inside the car. This might be thermostat, heater control valve, blocked heater hose or a blocked heater core. I would suggest letting the car warm up and checking the heater hoses (2) by hand to see where the hot water stops. If there is no hot water at all it is probably a thermostat problem.
Can a thermostat keep the heater from working in a 2001 vw passat?
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.
