squeeze the hoses to get any air bubbles out and refill coolant as necesary. are you sure you put thermostat in the right way? may be backwards. also may be your sensor.

SOURCE: Heater on driver-side blows barely warm air other vents blow cold

the most probabale cause of this would be a disfunctional hear core if you replace your heater your heater will more than likley work the the way it's supposed to

If the temperature gauge is reading normal, have the heater control valve checked.

A friend replaced my Heater Core for me and it still does Not blow Hot Air ...can you give me some trouble shooting ideas to check ?


Does the heater blower motor work? That is what blows cool air across and around the heater core and then through the case and out the vents as warm air blowing. The heater motor wiring circuit is separate, and gets pretty complicated with electronic HVAC controls, but it does have fuses.
If the blower motor works but you only get cold air, not warm, out the vents, then you have a problem with the heater case doors not operating properly. yes, the old temperature blend door problem, the actuator motors or the vacuum servos not operating the doors. By the time you get all that figured out and working again, you will be an HVAC expert in your own right. Your turn for a comment...what model and year of car anyway, are we talking about?

How do I fix the heat


You have one of two problems. The heater core is plugged /
restricted or there is an inoperative internal blend door motor problem. Start the vehicle and let it reach operating temperature. Feel the hoses under the hood that go into the heater core. They should be close to the same temperature. If one is hot and the other luke warm/cold.... the heater core is plugged/restricted. If both hoses are near the same temperature, suspect a defective/non operational blend door motor that controls heat/cold/airflow attached to the heater box assembly

Why does the heater blow cold


Could be a number of things from maladjusted air flaps, faulty servo motors, faulty climate control to a partially blocked heater matrix.

More clues are needed. The first step would be to ensure the engine is reaching full operating temperature and the hot coolant is circulating through the heater.

Erratic or intermittent heater operation can be an early sign of head gasket failure. It is easy to jump to false conclusions so I suggest getting some experienced help.

How can i fix the heat to blow hot air in my 1996 ford econoline250 cargo van


so either the blower motor isn't blowing or its just blowing cold air-always start with fuses-then check for 12v at the blower motor-use a volt ohm meter- if you have 12v then the blower motor is bad-if there is no warm air blowing out-look for the water valve that lets the hot water into the heater core-its on the small hose going back to the heater core-make sure its operating-cheers Denny

Just purchased a 2003 Ford Explorer Sport Trac XLT. Heater setting blows cold air. I tried all the settings from low to high. The fan blows the air into the cab but the air is cold.


it is either low on coolant, has air trapped in system, or your blend door is stuck in cold mode. rotate it from hot to cold, back and forth and see if you can see or hear it moveing. Some have vacuum motors that operate door, some have electric motors. report results.

Heater only blows semi warm air


Check the heater coolant flow valve is fully turned on when heater selected.
Check the temperature regulation & heat/demist air flow vanes are operating correctly,
Check motor operating temperature is as per specification- if motor running too cold replace the coolant thermostat.

A/C works fine but heater will not blow hot. Blower motor works


You need to check your heater control valve that operates the cold air door. Sounds like the door is stuck in the cold air position.
