Hello,

Sounds like a blend door, if this started up right after you had the core done it would seem to point to that.

What you have is a door or doors that are moved back and forth to blend cold & hot air, a "peg" is located on this door and a arm is connected to it, if that peg snaps off as it dose in most cases you get little or no action out of the door and it can be stuck in one position.

My advice is to take you car back to the place or person that did the heater core and tell them that you believe one of your "blend doors" was not hooked up when they did the work, they may check it for free, or not.

With luck the arm is just disconnected or something loose, you may or may not be able to look up under your dash and see the "peg & arm" but it's worth a shot.

Hope this helps.

My heater stoped working the a\c still works and fuses are fine


Either the heater core is clogged or busted, or a blend door is broken.

'94 Ford Taurus-No Heat?


Good point. Solving it will probably take more time than money.
Thermostats and heater cores do not work one day and stop the next. If your engine warms up normally and doesn't overheat, the gauge reads normally, engine is at normal operating temperature after about 10-15 minutes ...all these point to a good thermostat. It is working right and should not be a problem.
To check the heater core, wait till engine is at normal operating temperature. Turn heat setting to high, then feel both heater hoses-both should be hot. If both are hot the core is circulating coolant and is not a problem. If only one is hot (which would be the inlet hose) the core is not circulating-could be an air block or the core is plugged up and will need replacing.
If heater core and thermostat are good, then it probably is the temperature blend door in the heater case. The door actuator is probably vacuum controlled. I don't know how difficult it is to troubleshoot on your Taurus, but check if vacuum controls are working right from the dash controls, check if the blend door is stuck, is broken, or if the vacuum control is working to open and close the blend door. When you want heat, the blend door should let blower air pass across the heater core.
From the engine you will have a single vacuum hose that goes through the firewall into the dash to the heater/AC controls. There, a pod like device can rout the vacuum signal to various doors on the heater case.
Good luck.

2008 Jeep Liberty-My heater was barely warm-blowing fine tho. Was told I had a plugged heater core and needed a new one. Had a new heater core put in and then my air conditioner stopped blowing cold air....


I woild be checking the vent controls as if the ac is working and the core was blocked then the air would be cool when the heat was selected but not changing Fixing the heater has resulted in a /c not being good enough to cool the air if the vent is not properly selecting. The point is that if the vent selection is not working properly (vacuum hoses) then the 2 faults will be related.

Changed termustate and flushed radiator and toped it off still showin lowcollant and blowin cold are out heat


If you have a low coolant light, this would be a bad sensor, either at the radiator, or the coolant reservoir. need to replace it. as for the heater, well there are a couple of things to check. first,start the car, and let it warm up. now the engine is at running temperature, now turn on the heater(trust me), and let it run for about 2 minute. feel the 2 lines going to the heater core( they are on the passenger side going to the firewall) is the one coming from the engine getting warm, or hot. If not, there is a valve that allows hot coolant to the heater core. change this valve(they do go bad, or just get stuck), this is an easy fix. If the line is getting warm or hot, the problem will be the heater core, and will need to be replaced. hope this helps and please rate this, helpful to you or not

My 2006 ford explorers a/c runs cold and then gets warmer and then back to cold. i have on occasion heard a thump when the heat or the a/c is operated. i have been told that it could possibly be a vacuum...


There is a diversion valve that closes off the heater core. If there is an air pocket or if pressure bypasses that could cause the thump. And allow the heater core to warm up and in turn cause the ac not to blow as cold. It is like having the heat and the ac on at the same time. To fix this make sure cooling system is free of air, and check the diversion valve to ensure proper working.

My 1997 jaguar xj6 blows air but no heat. Can anyone help? I checked all fuses, and AC works.


the only thing that can change the air from hot to cold, or vice versa is the blender door. under your dash is a box which has 2 compartments. one with your heater core which is hot and one with ac which is cold. the blender door basically diverts which on the air in your car is being drawn from. if it is cold, air is moving on the ac side. if its hot, air is moving through the heater core side. if its warm, the door is in the middle. your temperature control knob is conecteted to an actuator, which moves that door. the actuator is a motor, but if it goes out, the door will be stuck on whichever side it is on. i would check that first. hope this helps

No heat engine gets warm but heater wont switch from ac to heat


Start searching for a vacuum leak. The dash switch operates a vacuum assembly - but if the line is cracked, it "door" will not change position.

Blend Door on 98 Ford Explorer


the blend door is roughly in the middle of air distribution Plenum assembly between the heater core and the AC evap core, it either directs air through the heater core or the AC evap core or mixes air from both.

Heating system blows only cold air


it maybe a blend door problem. if both hoses at the firewall for the heater are close in temperature its not likely a heater core. the actuator for the blend door is located on the bottom of the heater/ac box towards the middle of the bottom. it will be a tight fit but you can remove it without removing any part of the dash. take it off and disconnect the power. start the vehicle and manually move the door and see if the temp changes
