There is a vacuum operated control valve in the heater core lines at right rear of engine-the passenger side of engine. If it is closed, no warm coolant will circulate through the heater core. The vacuum signal for it comes from the heater controls at the dash. If the valve is stuck in the closed position, it may need taken off and cleaned or replaced. If the vacuum signal is not working, you may have to pull out the heater control assembly and check that vacuum lines are still plugged into the back of it.

My 2007 Pontiac g6 blows cold air in heat mode. Coolant level is okay


Possible blend door motor inoperative or restricted heater core. Once engine is at operating temperature feel the two hoses going into the heater core. They should be close to the same temperature. If one is hot and one is warm/cold, the heater core is restricted. If both close to the same temp suspect an inoperative blend door motor that controls airflow/heat inside the car

Heater not working


If a radiator and heater core flush doesnt fix the problem then it will be a blend door actuator located on the inside under the dash somewhere in between the middle to the passengers side. Test each one with a vacuum pump until you get heat; the one that causes heat to come out will be the bad actuator.

1999 chevy silverado heater fan only blows cold air , both coolant lines in are hot


I like that you were knowledgeable to check both coolant lines tells me you are getting hot coolant through the heater core next thing to check will be the blend door on the inside of your vehicle. The blend door is a door that switches from cold air duct to heater duct depending on what you are using at the time. If it is stuck on the cold air duct you will not get any heat sometimes these doors are vacuum actuated and sometimes they are electrically actuated most the time you are able to see the movement of the motor from inside if you don't see any movement but you hear it move chances are it is the door blend I hope this helps.

you need to check the heater control valve it sounds like the coolant is not flowing into the heater core and also make sure the coolant level is full, just because it doesnt overheat mean that the sysyem is full, another problem is the core plugs up yoou may want to flush the heater core with a water hose first, remove the two hoses to the core then use waterhose with a nozzle and stick on one side of the heater core end and flush then do the same to other side to this a few time switching from side to side connections, hope this is helpful.

No heat inside the car


Check the two tubes entering the firewall that lead to the heater core. If both get hot, then the inside blend door is not actuating correctly. If the heater core tubes are cold, then the heater core is blocked up.

Have the car's cooling system backflushed or replace the heater core in order to fix the problem.

Good Evening, you are doing all the right things. However have you tried flushing the heater core, most times the heater core itself can have some build up inside and you get no heat in the cabin. The first thing to do is to check the heater hoses if one is hot and the other is not then I would look there. Second I would also check inside at your blend door and see if it is switching over when you move it from cold to heat. Those would be the places to start. Hope this helps.

Heater doesnt work blows cold air, replaced thermostat and flushed heater hoses appears to have no flow through heater core, but lines arent plugged on a 1995 gmc sonoma. Why is the hot air not flowing...


This is what I did to solve the exact same problem.I got a pump that you can hook to a drill that has garden hose connections on it.I made 2 hoses to pump into my heater core and hook to the pump. I bought some radiator cleaner at Auto Zone and put it in a 5 gallon pail with about 2 gallons of hot water.I pumped the cleaner from the pail into the OUTLET side of the heater core.(By going in the outlet side you are back flushing the core.) I put an old cloth over the top of the bucket and let the outcoming cleaner run onto this cloth acting as a filter for the dirt coming out of the heater core and let the pump run about 10 minutes. Believe me,A LOT!!!!!!!!!!! of dirt,rust etc. came out of my heater core. The heat now works excellent! Good luck.

THE BLEND DOOR THAT CONTROLS HOT TO COLD SWITCHING IS STICKING. THE CONTORL HEAD IS ELECTRIC AND MAY BE CAUSING THE PROBLEM. HEAT AND AC ARE 2 COMPLETELY DIFFERENT SYSTEMS EXCEPT FOR THE CONTROLLER UNDER YOUR RADIO. HEATER COIL IS REALLY A HEATER CORE WHICH IS A LITTLE RADIATOR INSIDE THE CAR BEHIND THE DASHBOARD.

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
