You just might have an air lock. Try bleeding the system from the heater hose at the firewall. Losen one hose a little, and at operating temp. open slightly to let air out. You will lose some coolant, but just refill the rad. Now, both hoses should get hot.

SOURCE: 2002 traurs no heat both

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.

2000 dodge caravan heater blowing cold air only car does not overheat


Feel the heater hoses where they go through the firewall. If they're both hot but you're not getting any heat, your blend door is not moving to mix heated air with unheated air. It could be the blend door actuator not working or the HVAC control unit not working.

Air conditioning only blows cold air.


Can you hear the blend door moving when you change the temp from cold to hot or vice versa? If not, then you need new blend door actuator. Also check the heater core for any blockage. (2 ways to tell....run the car til normal temp, and turn on the heat and feel the hoses by the firewall...if one is hotter than other, there is a blockage inside the heater core. Or disconnect both hoses at firewall, and put garden hose in one of those 2 open tubes and turn on the water...good flow or weak flow coming out of heater core tube? Weak flow means blockage) If there is a blockage, time to get new one.

No heat replaced heater core thermostat


So the blend door opens? Does the fan motor blow? Are both heater hoses hot? That would indicate the coolant is circulating through the core.

I have a 2000 jeep wrangler when I turn on the heat or defrost I can hear it running but I get no heat. What could cause this heater coil, thermastat or something else maybe?


Is coolant level full? To check if the heater core is circulating coolant, feel both heater hoses where they enter the firewall-both should be hot when car is at normal operating temperature. If only one is hot, look for a heater valve in the heater line-make sure it is open so the heater core circulates. Not all vehicles have such a valve, in fact, I think most don't have the valve, but you could check. The valve may be cable operated or vacuum operated to open and close. If no valve, and one hose is cold, there may be an air block in the heater core. Crack a line loose to get coolant circulating.
If both hoses are hot, it is probably the doors in the heater case not operating properly. Watch the door actuators when you move heat from cold to hot, and when moving from defrost to another setting. The temperature blend door is probably on the passenger side of heater case. These doors may be cable operated, vacuum operated, or electrical motor operated. If you watch for their operation, you might see or hear the problem with them not opening or closing properly.
Good luck.

Check to see that the blend door linkage is hooked up. Doubtful it is heater core, as you had heat to one side and not the other. Check coolant control valve linkage, verify it is moving the coolant valve from off to on when you switch temperature from cold to hot. Verify you have coolant flow to the heater core by feeling the heater hoses where they enter the firewall. If all checks out well, then look at hvac controls individually.

1994 pontiac firebird HAS NO HEAT


Okay. warm up vehicle, get radiator hoses hot.  Turn on heater, fan on low.  Grip both rubber heater hoses close to the firewall, from the engine compartment side.  They should be too hot to hold for long.  If they are not hot, then you have a lack of coolant circulation to the heater hoses.  If they are hot then access heater core, behind glove box area.  Blend door which moves as you chose HOT or Cold, should be cable controlled, move the controls and be sure the door is actually moving. Keep me posted

Heater valve


there is no heater control valve in this truck, heat control is done through what are called blend doors. So the issue may be the front blend door motor has failed, this is very common on all Ford heatimng systems except the Focus.

No heat


Check the hoses that go through the firewall into the heater core to see if they are hot. If they aren't you may have air pockets that need to be bled out of your coolant system. If they are hot, you may have a bad vacuum supply to your blend doors. You should have a vacuum supply hose under the dash toward the center. If you have a good supply, you probably need to tear down and inspect the ductwork and boxes.
