air is bled out of the coolant system and a new thermostat ,(195
degree),make sure the heater control valve is working also,the heater hoses
should get really warm to touch ,or hot.

Did you change the heater door as in "heater-treater"--I did --now have heat and cool. It was quite a job! Look for "heater-treater" on internet. When door breaks you will have all cool air or all hot air.
I have a huge problem with the heater in my 2002 explorer. I have replaced the theromostat, heater control valve and the blend door in my dual control system with the heater treater door. The door works fine opens and closes as should. The problem is I get very hot heat out of the low vent on the floor, ice cold air out of the vent near knees and luke warm air out of the vent on the dashboard. The car seems to not want to make heat at all when the AC compressor is on such as when defrosting. Temperature of coolant through heater core is 154. The car engine warms up to normal temperature. The heat is there but can't get it to come into the cabin of the vehicle. I have looked under the dash at all of the vacuum controled doors and all seem to be working as to where the air comes out. Just can't figure out why it is not hot. Any ideas? I'm open to all.

What you describe is SOP for one of their designs.

I had the same exact problem and I have the same exact care as you! Someone on this forum actually told me exactly what to do and it works. It may take you a short while to find it, but once you do it will be very easy! You need to open your glove compartment and squeeze the two sides so that it will drop down and give you access to inside the dashboard. Place your hand inside and to the left side and a little bit down until you feel a lever. You will need to push that lever down (towards you). The heat dial needs to be turned almost all the way to the hot side in order for the lever to stay down. If it doesn't stay down, shimmy that dial just a little either way until it does. You may need to do this each time you restart your car. Sometimes it stays, other times it pops out each time you turn off the car. Below I am pasting the exact wording that the guy that helped me posted, because I think it was a very good description. I know how terrible it was having this problem last year. I'm sure your heat will work like this as well. Here was the guy's wordage:
"Just found the lever an hour ago.......I have a 2003 explorer. you have to release the glove box ( not all the way out) and put your right hand inside toward the a/c heat controls right inside and toward the bottom of the left side of the glove box....you can feel a small lever vibrating slightly.......its about 4 inches down....i pushed the lever down and my heat started working..........(had the car running and the heater turned on)...............hope this helps. Have to figure out some way of tying a string on it though as the lever wants to move back to the shut position. "

It is really kinda hard to get to, but if you can manage to get to all the screws loose great! we only had to take off the panel near the floor to get to it, but when you get the screws loose, and take out the box, you have to open it up and look at the teeth of the gears, if they are not broken off or chipped then thats not your prob. my gears were broken. you can do 1 of 2 things. if the gears are broken, you can go to an auto store and order a new actuator, which is around 40 some dollars, and then just put the new box in, replace the screws, and your finished....lol i actually have a quick fix solution while your waiting on the part to come in. when you open up the box, there is a piece that sticks out of the box, that fits into a slot in the dash that connects to the blend door. if you take that piece out of the actuator, just that one piece....and stick it back in the hole in the dash, you can manually turn the heat on by flipping the piece either forward or backward, but the blower will have to be turned on for it to stay on. but this is a quick fix and it will give you heat, until you get that box replaced. if you have any questions, or this doesn't make sense let me know...
I posted this last year sometime and I hope this will help you, this problem has not come back for now...they have the part I am talking about above at any auto parts store for 40 or 50 bucks, which def beats the $700 your talking about...I also put in there a quick fix to help you until your part comes in, or if you just don't have the cash. Please email if you have any questions
Thank You,

So... there's this "blend box" were the amount of cold air and hot at is controlled with a motor and some kind of interior door.? I have located the blend door actuator on the drivers side and decided not to tackle that monster until I have more information. Very difficult to remove. I've also located a lever directly across from the motor on the other side of the blend box on the passenger side. It is accessible a lot lower than behind the glove box. Mine is a little higher than just behind the middle console cover that is removed next to the passenger floorboard. Its hard to find. It basically sticks Up when the temp control knob is in the cold position and can be moved, towards you and down, when the engine is running, in park and the as other have described for heat. This will control the hot and cold so at least I can get it to work.
I've known that this problem is going to cost me a fortune since it happened. and I'm pretty good Mr. fix-it. I think I'll look at the blend door fix from heatertreater.net and also talk to the part dept about the blend door actuator replacement and see if the problems I am having are symptomatic of what they might see regularly. I'm also going to see if I have simply missed a lever or vacuum hose that is broken. It sounds to me that Ford has multiple problems here and I want to make sure I get the right one. I'll keep you posted as I find out more.
I have a 2003 Explorer XLT and currently having the exact same problems. I started with the blend door fix from Heater Treater, last March. I recently started snooping around for the reason that the heat doesn't make it to the dash. Here's what I found.
If you pull the instrument cluster,(speedo and and fuel guage and things) out of the way. To the far right there will be a little hole. Shine a flashlight in the hole and move the selector for the hvac controls to defrost clicking one at a time work your way to off. There is a vaccuum actuator there that connects to a door,(similar to the blend door), mine is broken off. If you see a lot of movement in and out as it moves front to back, I bet you have the same problem.
I am working right now to see how involved this will be to change. It looks like you have to remove the whole dash. I will let you know what I find.
With the glove box open and looking in to the left there is a steel bar hooked up to a vacuum actuator that points forward towards the rear of the car. This actuator is triggered by the movement to defrost and appears to be working a-ok. Also in that extremely sharp and hard to see space is the exposed hinge of the blend door that has the lever on it that triggers the heater core when in full cooling mode.
What am i missing? Could someone take a picture - i desperatly want my heat back as its getting cold up north!
I really hope this helps you
If not, please feel free to get ahold of me!
Thanks

compounds the problem I believe it is in the switch as it works on only High and next lowest
speed for the summer. Now with winter and the need to defrost or de-ice it is critical.
Could it be a fuse or loose connection?
is it in a different position than the other model years? Next I have no fan movement
In the front of the vehical . Only in the rear. I had high and next high speed up to
a week ago. Has a fuse blown? when inside the dash I wiggled the wires to the switch
but did not get the fan to work. Are these problems related? This is now critical for
de-icing and defogging let alone heat.
Your description of the problem is identical to my issue.
I have a 2004 Ford Explorer 4.6l Eddie Bauer with Dual Climate Control.
I purchased the HeaterTreater Blend door thinking it would correct the problem, however after I took out the actuator motors (the dual climate control system has TWO), I discovered the BLEND Door was find and both actuators were working properly also.
I want to know how you were able to fix your problem.
Thanks
Good luck.
Thanks

Also when I purchased the vehicle, the dealership said they needed to add refrigerant. It lasted only two weeks at minimal useage. I added 2 more cans and no cold at all. HELP Im hot all the time!!
