SOURCE: heater not working, blower not putting out hot air.

There are two other good possibilities.

1) You may have air in the cooling system. A small leak can cause air, or if you've recently had the system drained/flushed or had any hoses replaced, air can get trapped in the system. Some models are equipped with bleed valves, usually on the thermostat housing, which allow the air to be bled out. Other systems can be bled by opening a flush valve or simply by releasing the radiator cap while the engine is cool and waiting.

2) There is a vacuum controlled flap style door that blocks access from the duct work to the heater core. This door remains closed when you have the heat off, are using AC or just plain blowers. It only opens when you select one of the "heating" modes or a mixed heat mode. If the vacuum line is plugged, torn or pinched off, no vacuum can get to that door and open it. Some doors have a cable that opens them, but it is still connected to a vacuum operated lever.

I'd check the vacuum hose first. If that's not it, move to checking your cooling system for air, or have it checked. They are both relatively inexpensive fixes compared to replacing a heater core.

Do you have enough antifeeze in your cooling system. If not fill & check again for heat. You may have a blockage. If so remove the in & out hoses to the heater core on firewall. Be careful not to damage core. Use a garden hose to flush the core one side to the other untill running clear water. put one hose on tight & clamp, put other on loose. Have someone start engine & slowly remove loose hose to let air escape. when fluid appears put hose on & tighten. Refill rad & resevoir. Heat engine up & check for heat. Also heat cable may be off under dash.

SOURCE: Heater does not come on, Radiator fluid full.

Probably air locked. check to see if one of the hoses leading into heater is hot. Other cause could be heater solenoid control valve faulty. Very unlikely that the heater matrix is blocked. Easiest way to bleed heater is to remove hose's when car is cold and GENTLY flush through with garden hose and push hoses back on when full of water, so you know you have a heater full of fluid. Hope this helps

I have a 2005 hyundai elantra heat blows cold air i changed thermostate and radiaor and blew out the heater core any sugestions


check to make sure the blend door is changing from cold to hot. With the engine off and the key in the run position set the blower motor to the highest speed. Turn the temp dial to full cold and wait 30 seconds. Now turn the temp dial to full hot a listen carefully. You should hear a difference in sounds as the blend door sweeps through its full range.

If it is working and the engine is fully warmed up feel the heater hoses where the pass through the fire wall. One should be very hot and the other should be pretty warm. If one is hot and one is significantly cooler than either the heater core is plugged or there is air in the heater core causing a block in flow.

If the heater hoses for the front heater are getting hot, it could be a blend door problem under the dash.

No heat in cab. Blower working fine.


Make sure that you have enough coolant in the system and that it is getting to the heater core. Also make sure that the blend door on the heater box under the dash is moving from cold to hot. Also make sure that the temperature knob on the console is actually turning to the hot side and not turning.

Lack of heat


Sadly "there" explanation is probly correct, when you say you have some but not alot of heat on low and then almost non on high, that is due to a plugged heater core. A heater core acts as a miniature radiator inside your cab. When the fan passes the air by it it picks up the heat and blows that into the cab. While doing that it also cools down the heater core. The more are you pass by it the cooler the core gets. What you can try first before replacing it is a coolant flush. This will run a mild acid like sollution through your entire cooling system. Sometimes that alone is enough to let more hot antifreeze run into your heater core thus giving you more heat. Another option is to disconect both lines into your heater core from in the engine compartment and run a hose into one , leaving the other to drain out. Depending on how plugged it is sometimes you can "Flush" out the buildup this way as well. G'luck and keep warm!
