Blend air door may be stuck. I removed a pencil from a heater box before. It had fallen from the dash, down through the defrost vents and jamed the door.

SOURCE: how to replace blend door actuator in a ford

I recently did mine, I hear you can do it without taking the entire dash apart but I had no luck with it myself. I have to get ready for work but, on mine it was located down and to the left of the radio. its a white box...are you hearing a clicking noise or something? I had to roll the entire dash back and it was still a major pain getting it out.

Heat troubleshooting


<span>There are a few reasons this might happen to your system.<span> </span>A typical system is shown in the diagram below:<span> </span></span><br /><br /><br /><img src="CC87E1A.jpg" /><br /><br />The system requires hot water from the engine to pass through the heater core and the blend (or mix) door positioned for air pushed by the blower motor to pass through the core.<span> </span>If the <a href="/../cars/r6235876-no_heat_fan_blowing_cold_air#">vehicle</a> has no air conditioning, the evaporator is absent from the system.<span> </span>Some designs also incorporate a control valve in the heater hose to stop coolant flow to the heater core when not in use. The blend door position is actuated by a stepper motor or cable.<br />Typical failure modes are as follows:<br /><span><span>1.<span> </span></span></span>Blend door stuck<br /><span><span>2.<span> </span></span></span>Blend door actuator failed motor or stripped gears<br />3. Blend door cable is broke or needs adjustment<br /><span><span>4.<span> </span></span></span>Temperature control switch failed<br /><span><span>5.<span> </span></span></span>Air pockets in engine cooling system<br /><span><span>6.<span> </span></span></span>Clogged heater core<br /><span><span>7.<span> </span></span></span>Heater coolant control valve failed closed<br />8. Thermostat failed open<br /><br /><b>Troubleshooting:</b><br />First, with your engine hot and the heater turned on, feel the heater hoses in the engine compartment as they attach to the heater core at the firewall.<span> </span>If either of the hoses is cold, the problem is likely a lack of adequate coolant flow.<span> </span><br /><br /><b>No or low coolant flow:<span> </span></b><br />Check for the presence of a control valve in one of the heater hoses--trace the hoses all the way to the engine.<span> </span>Not all vehicles have such valves.<span> </span>If you find one, check to see if it is actuating properly.<span> </span>It should receive a signal of some kind from the heater controls and open when the temperature control is turned to heat.<span> </span>If you cannot determine that the valve is opening, try taking one of the clamps off and removing the hose to see inside the valve. A typical vacuum operated heater flow control valve is shown below:<br /><br /><img src="7FA590D.jpg" /> <br /><br />The valve may also be actuated by a solenoid or wire cable. <br />If you have no valve, next check the cooling system for air. If you have a radiator cap, take it off and look inside.<span> </span>If it is not full, fill it with coolant and start the engine.<span> </span>Turn the heater on and let the engine run until it is warm and the thermostat has opened.<span> </span>Continue to fill the radiator or reservoir until the level stops falling.<span> </span>Check for the presence of any bleed ports in the system.<span> </span>Bleed ports may be on the housings that radiator or heater hoses attach to or may be installed in the hoses themselves.<span> </span>A typical Honda application is shown below:<br /><br /><img src="C655B97.jpg" /><br /><br />For stubborn cases, p<span>ark the <a href="/../#">car</a> uphill, take cap off radiator, start <a href="/../cars/r6235876-no_heat_fan_blowing_cold_air#">car</a>, fill radiator, let it warm up until <a href="/../#">thermostat</a> opens, bleed air out, fill to the neck of the radiator and watch for bubbles coming up. Once you have bled the air, if gas continues to come out, you may have a blown head gasket that is forming bubbles that can block coolant from entering the heater. In these cases, the heater may work well at speed but blow cold at idle.</span><br /><br />Clogged core: If the control valve is open and there is no air in the system, your heater core may be clogged.<span> A quick way to check for a clogged core is to turn the blower motor off for a while and then back on. If it produces warm air for only a short time and then cools down, your core is only passing a small amount of coolant. This can also be caused by a bad control valve, if you car has one or possibly by a weak water pump. </span>You can try flushing the core by removing the heater hoses and attaching a garden hose or other source of water pressure to force water through the core.<span> </span>Use an adapter to make a good seal and connect to the lower pipe to backflush the core.<span> </span>If the core will not flush or allow adequate flow, replace the heater core.<br /><br />Thermostat: if your car temperature is running cold and only warms up when idling, the heater will do the same. This is caused by a thermostat that has failed open, allowing too much coolant to flow through the radiator. <span>.</span><br /><br /><b>Blend door not moving to heat position:</b><br />If you have coolant flow through the heater core, the problem is with the blend door.<span> </span>The blend door is almost always actuated from under the dashboard.<span> </span>Many systems use an electric motor to actuate the blend door.<span> </span>Check any heater or A/C fuses before tearing into your system.<span> </span>You may need to remove a partition to see the actuator.<span> </span>The door should be to the right of center under the dash.<span> </span>A typical electric motor actuator design is shown below.<br /><br /><img src="4ED4FC8.jpg" /> <br /><br />The actuator can be on the top front or bottom of the duct.<span> </span>Consult a manual for your vehicle if you cannot locate the actuator.<span> </span>Once you can see the actuator, watch it while you change the temperature setting (key on unless it is cable operated).<span> </span>If the actuator doesn't move or turn, troubleshoot the reason.<span> </span>Systems such as the one in the above picture typically fail in the shaft attach or the internal gears on the actuator.<span> </span>If your actuator is getting power but not moving the door, replace the actuator.<span> </span>If the actuator is not getting power, troubleshoot the control switch.<span> </span>Due to the wide variety of designs, we cannot provide test tips for electric blend door control switches.<br />Whether your blend door is electric or cable operated, remove the actuator and operate the door with your hand.<span> </span>If the door sticks, the heater box must be removed and opened to free the door and restore unhindered operation.<br />If your blend door is cable operated, check the cable for proper attachment at the control lever and at the door lever.<span> </span>The cable sheath must be properly adjusted and firmly clamped for proper operation.<span> </span>To adjust, first remove the cable from the door and move the door lever with your hand to observe the range of motion.<span> </span>Then set the control to full hot, open the door fully, and reattach the cable, clamping the sheath so as to ensure the door opens fully when set to hot.<br />

2008 ranger blend door not working


It can be a jamming door has damaged the actuator motor, both problems are common on this truck. You can buy a kit on line that is called a "HEATERTREATER" THAT ALLOWS YOU TO REPLACE THE BLEND DOOR WITHOUT REMOVING THE DASH, EBAY ALSO HAS THE KITS.

We replaced the blend door actuator and heat control switch on a 2005 ford explorer now we get heat when you swith the contro from one side to the other then theres a loud boom like the blend door is


You should have replaced the blend door as well, they have an issue with warping and the noise is the door being broken free by the actuator, which will shortly fail working this hard to move the warped door. Have you ever heard of a kit to do this without removing the dash called "Heater Treater", google it.

Heater blower works just don't get any air at all


The heater blend door actuator is not opening the door.Check for power at the actuator and if you have power at the actuator and its not working then replace the actuator.These actuators are a well known culprit of this problem.You find the actuator behind the glove box it will have a small arm on it that operates the heater blend door.

My 2004 Avalanche ' heating system will not heat. No matter what the setting it either blows no air or cold air and it is 25 degrees outside so this is a problem. The engine is up to temp and I have tried...


The most likely cause is a failed blend door actuator; however I recommend a little troubleshooting. First, can you hear a clicking sound behind the dash when you turn the setting to hot? If yes, it is certainly the actuator stripping its gears. If not, check to make sure the heater hoses are both hot as they connect to the heater core at the firewall (in the engine compartment). If one or both of the hoses do not get hot, there is a blockage caused either by an air bubble or a stuck water control valve in the heater hose. If the hoses are both hot, the indication is again the blend door actuator.

Below are instructions for replacing the actuator. Look at the diagrams carefully--the big arrows point to the front of the truck and the actuator is on the side of the heater box above the outlet duct that runs to the driver's side of the floor. Also, the actuator is expensive, so I recommend you make sure it's bad and shop around a bit to get a good price. To check out the actuator, first see if you can turn the blend door by hand. If you can't turn it, maybe it's jammed. Also, reconnect the actuator after removing it and see what it does when you turn the heater to hot.

Removal & Installation
  1. Remove the floor air outlet duct extension (1) from the floor duct (2).

Afternnon, just wondering about the best way to locate the blend doors in the hvac box without ripping out the dash on my 2000 jeep grand cherokee. Thanks in advance. Duane


y9ou can gain access to the driver side blend door actuator by removing the glove box. The actuator will be in the left corner of the glove box opening. If you remove the actuator you will be able to turn the pin. If you can turn it 360 degrees the blend door is broke.

If your lucky its only the drivers side. If you get the repair kit from chrysler it will come with instructions with pictures on how to replace the blend door without pulling the HVAC unit/Dash. If the passenger side is broken the HVAC unit will need to be removed.

Heater treater (google them) also have a metal blend door replacement and instructions online on how to replace them without pulling the HVAC housing.
