The thermostat may be stuck open. Is the car overheating? is the low coolant light on?if you answered no to both questions..let the car cool approx three hours.. start the car and feel the upper radiator hose, you shouldn't feel any pressure or water running through it until it reaches normal temp range, then the hose will become hot.
If the thermostat is stuck in an open loop you will only get a very slight amount of heat and it will also affect your fuel economy. if you checked everything and it checks normal, then i would suspect a bad heatercore.

Why does it take a long time for heater to come on?


The heater works with the hot water of the car radiator, on colder days it takes the water sometime up to 15 minutes to get hot. The heater in the car does not use electric heating etc, the safest form of heating inside the car is done through a fan running over a water heated core.

Have an antifreeze leak coming from either the heater coil or back of the motor not really sure.


I'm pretty sure if it were the heater core, you would have antifreeze soaking your carpet, and the inside of your car would smell of antifreeze. Your inside windows would also fog up when you turn on the heater.

Antifreeze steam comeing through vents


Your heater core has a leak, it's like a small radiator that heats up and the blower motor blows air thru it to create heat in the car. It is leaking anti freeze into the heater box.

My heater doesn't come on for my 1997 plymouth neon, could it be a fuse?


There are many many reasons for car heater not coming ON or not working properly:-- i will explain you the procedure to check this possibilities Your car's heater is a life saver in cold weather. Before attempting to repair your car’s heater, you should understand how your car’s heater system works. First, on this page is an explanation of how your car’s heater system functions, further down the page are some pointers on heater system trouble-shooting. To warm the passenger cabin of your car, your car’s heating system makes use of excess heat from the engine’s internal combustion process. A car’s engine, in fact, when in operation produces so much excess heat that if the excess heat is not removed, it would destroy the engine. It is your car’s cooling system that removes that dangerous excess heat. Some of an engine’s excess heat is released through the exhaust. Most of an engine’s excess heat is absorbed by a circulating liquid coolant, which is a mix of water and antifreeze.

The heated liquid coolant is carried from the engine through hoses to the radiator, which transfers the heat from the coolant to the outside air. That heat transfer lowers the temperature of the liquid coolant, which is then circulated back to the engine to absorb excess heat again. Whereas the radiator is located at your car’s front grill, the unit that transfers heat to the passenger cabin is located inside the dashboard. This unit is something of a mini-radiator and is referred to as the heater core. Heated liquid coolant circulates through tubes in the heater core and a heater fan blowing across those tubes, as well as through little fins encasing the tubes, directs warm air through heating vents into your car’s passenger cabin. Because your car’s heating system works off of its cooling system, heating system malfunctions are often caused by problems in the cooling system.
The heater core in your car is similar to the radiator in the front of your car; in fact it looks like a small radiator. The difference is the heater is mounted inside the car and air is blown through the fins of the core. The heater hosestransfer engine coolant from the engine to the heater core, this allows the heat from the engine coolant to be utilized and warm the passenger compartment. When a heater stops functioning determine what type of failure has occurred to execute a repair. We have listed the most common problems below.

1999 ford windstar heater lever will not turn on front heat


Check on the heater control valve. It is probably close to the firewall behind the engine. There will be coolant lines attached to it. This valve should have an arm on it that opens and closes a valve inside, either shutting off or allowing hot coolant to flow into the heater core. The arm should be attached to a cable coming from inside the car. See if the arm moves when you move the heat temperature level inside the car.

could be a number of things could be a plugged heater core or a faulty thermostat. If there is heat coming out then it is probably not the thermostat unless it is stuck open. If the heater core is plugged you may smell antifreeze inside the car and have no heat then the heater core could be the issue.

No hot air FROM HEATER inside 2000 318IA


Hi There, If the fan blows only cold air, then you might have a restriction on the heater core. The heater core is like a small radiator inside your dash. The coolant flow through it can be restricted by corrosion. The lack of flow of coolant through the heater core will result in a lack of warm air inside the car. Flushing out the heater core may help. If not, you will have to replace it. I would say though, 80% of the time the cause is just restriction. Get the heater core flushed and I am sure you will get your heat back. MIke
