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

2001 Pontiac sunfire doesn't put out hot air when put on hot setting only warm air


Your coil that allows air to pass through for A/C or heat could be plugged or the thermostat is sticking.

2002 traurs no heat both heater hoses hot blend door seems to work new thermostat


i just went through this in my 2001 F250. first check to see if you have flow switch in your heater hoses. this opens and closes to let hot water in your heater core. mine did not have this, but here is what my problem was. i had used that pink antifreeze. it slimmed up in the heater core. i blew air through the core and un plugged it and had heat. it was hard to get that stuff out as i flushed the system 2 times and put in green antifreeze. in desperation the 3rd time i blew air through and got it clean and that was the end of my heat problem.

The heater only blows cold air,the radiator is full,thermastat is working and the engine temp is within normal ranges.


I've had this problem. 2000 GMC uses a closed coolant system. Meaning takes and returns coolant from and to the Reserve Bottle and has little air in the engine and heater systems.
If everything appears ok but no heat. "Air Lock" is the most likely cause. (With interior heater set to full heat) Solution; 1. Make sure water pump works. 2. Drain about 1/2 engine coolant into container. 3 Remove both heater hoses from engine side and flush heater core in both directs through heater hoses with garden hose. 4. Reattach heater hoses in correct locations. 4. Refill engine with coolant. 5 Start engine and run for 2 min., use caution when topping up coolant.
6. Most 2000 GMC have twist off caps with plugs located mid way on heater hoses. with engine cold, start engine these caps may be loosened to allow trapped air to escape. Do not attempt with engine hot due to hot coolant injuries. This may take more than one attempt to remove all air from heat system. 7. Lastly most 2000 GMC water pumps have a bleeder plug,( 3/8" square driver plug) located on the water pump. With egine cold this plug should be removed to remove any air. Reinstall plug with thread sealant.
Hope this helps cheers

1995 cadillac deville 4.9 eng no heat


The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.

No hot air from heater, blower runs fine

Since you state the 2 things you ruled out, that leaves only the water pump. Is the car running hot? The thermostat may be sticking as well... but im leaning toward the pump.

To attempt to clean the core, you must flush the system multiple times. If this does not work, the core cannot be cleaned and must be replaced.

I have changed the theromast twice and flushed the coolant system.The heater core is not leaking.. the blower is still blowing cool air.

if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.
