    I just got to your other post with the video link in it and I know what our problem is here. You have a 2001 model, which has a different blend door box set up than the 2002-2005 models, which is what I was giving you the repair instructions for. I wasn't aware the older, 2nd generation Explorers had blend door actuator issues like the 3rd generation 2002-2005 Explorers have. Your blend door box is behind your glove box as in the video and mine is under the center dash console area. So follow the video instructions you have and yes, that white box the guy pulls out in the video is your blend door actuator you are looking to replace. Yours is actually a lot easier to replace than mine was. A lot easier to get at. Make sure you follow those instructions on how to properly set up and install the new actuator. Use your vehicles VIN number when ordering the new actuator from Ford to ensure you get the right part for your exact vehicle. You should be good to go from here. Good luck!
    BTW, even though you mentioned your vehicle year in your first post, it might be a good idea to list your vehicle specs under your screen name, so people can see what type of vehicle you are asking for help with each time you post a new message in here.

    If you have a 2001 Ford Explorer, then go with the instructions from AA1Auto in that video link you showed me, that is where your blend door actuator is located, inside the glove box area and much easier to change. Don't go with the repair post instructions I first gave you that are from "BigRondo", his instructions are for people with Explorers that are from years 2002-2005 and have the blend door actuator located under the center dash console area and much harder to change. I originally thought you had a 3rd generation Explorer, years 2002-2005 and that is why I gave you a link to BigRondo's repair post.

    If you know where it is, then why did you say the following below?

    >>>>>>>>> (I asked about under the radio someone said yea.. that the post I went with really.. >>>>>>>>>

    Your actuator is not under the radio, it would be if you had a 2002--2005 model Explorer, but you have the 2001 model, so it's located thru the glove box. If you skim thru the posts people are sending to you because there are too many "words" for you to read, you will most likely skip over important information pertient for the repair help you seek. I didn't skim over your posts, and I looked at your pictures of the inside of your EX and engine compartment, which really showed me nothing to go with as to your heat loss problem. I'm also not very familiar with 2nd generation Explorers and most of the people coming in here with blend door actuator problems since I joined the forum have 3rd generation Explorers.

    I told you the general area where the heater core valve would be located in my previous post. I don't know the exact placement of it or even if your '01 Explorer even has one, but some Explorers do have them and it has been the source of lost heat into the vehicle. From the pictures I have seen of them, the valve would be located along the passenger side valve cover area(about a foot or so from the firewall), connected into one of the heater hoses. If you don't see one there, most likely your Ex doesn't have one. Just follow the heater core hoses from the firewall back to the water pump/engine and see if anything that looks like a valve is connected inline with them. I would think there is an electrical harness plugged into it as well, but I'm not 100% sure. One other thing, make sure your coolant level in the expansion/overflow tank is up to the "full level". If you somehow got an "air pocket" into the system it could cause loss of coolant flow to the heater core, thus loss of heat into the vehicle. To purge any air out of the system and with the coolant level full, squeeze the upper radiator hose with your hand numerous times and see if you get any "air bubbles" rising up in the expansion tank, that is air in the system . Do this with the expansion tank cap off and the vehicle turned off. After doing this, re-cap the expansion tank and drive the vehicle with the defroster on, set to hot temp and fan on high and see if you get heat. Only do this if you suspect air in the system. Usually after doing an anti-freeze coolant flush and re-fill, you will have to do this as well because air can get into the system during that procedure.

    You didn't tick me off, but I did previously mention where to look for the heater core valve. The heater core valve if you have one on your Ex, will not be hard to find. The heater hoses are only approx 2 1/2 to 3 feet long and it would be clamped into one of those hoses. If you don't have a heater valve, only other things I can come up with is either your heater core is plugged up, the blend door itself is bad or you somehow installed the new blend door actuator wrong and it isn't working properly. When you installed the new actuator, was the dash temp knob set to the cold side and was the blend door itself set to the cold side? This is where they both needed to be at installation time, set to cold temp. Did you test the new actuator by plugging the wiring harness into it, energizing the ignition with the key(not starting it) and turning the temp control knob to hot, watching the actuator arm rotate prior to mounting it in place? Then returned the dash temp knob to cold along with the actuator arm to cold position and then installed it with it's mounting screws? This is the proper way to test the actuator and the position it should be in prior to install. Thats all I can come up with up as to why you are not getting heat thru your heater core.

    well I took it into the shop... they flushed forward and backward.. still wont stuck... really good.. However the hose is now getting hot. They said they want me to leave it over night so they can pour some stuff into the heater core to losen it up.

    So the shop did verify that the heater core itself was plugged up? Try and find out the name of the chemical or product they plan on using overnight to unplug the heater core blockage? I'm curious to know what they used and I'm sure some others in here might want to know that information as well. Post an update when it's repaired. Good luck!
