The usual symptom is an inability to effectively control the temperature in your car. Note that this symptom can also be caused by a bad temp control knob, and this is a common failure on Ford trucks. Please check carefully before considering the blend door fix.
The blend door hangs on a vertical axis, so turning a sharp corner, or fiddling with the fan speed can swing the door into the hot or cold position randomly. While the symptoms are fairly conclusive for blend door failure, the only way to really check it out is to remove the blend door actuator motor and look at the axle.
Another reported symptom is a clicking sound coming from the actuator motor. This occurs when the motor gears get out of alignment and are slipping against each other, making the noise. Sometimes you can make it stop by pushing down on the back of the motor and getting the gears to catch. The failure usually occurs with a broken blend door that allows the motor to get out of alignment and twist slightly, causing the gears to disengage. Heater Treater will put the system back in alignment and correct this problem.
Our goal is to make sure that every installation is successful. To date we have achieved 100% success and have no intention of letting up. Heater Treater will solve the problems with the blend door and is over-engineered to outlast your Expedition.
“This Has Been The Best Internet Purchase We Have Ever Made”
“I ordered Heater Treater for my ’02 Jeep Grand Cherokee with a little doubt in my mind. Once we got the part the instructions seemed a bit more complicated than we expected. When we were ready to attack the project we watched the videos…… WOW. With the video you almost don’t need the instructions at all. Worked just like you said it would!!
This has been the best internet purchase we have ever made. We will be telling everyone we know about your product. Easy installation with exceptional results!!!! Definitely worth the price, saved us at least $1500. Thanks!”

The Best $120 I’ve Spent All Year”
“All,
Not only was the Blend Door Fix super easy to install, but it is rock solid, and it works a treat. Definately the best $120 I’ve spent all year!
I was dreading another Winter without a heater so much that I was actually thinking about selling the Jeep and buying a new car….so at the very least you’ve saved me $1000+ for a repair by a mechanic, but you’ve quite possibly saved me about $500 in car payments per month for the next 60 months!”
Many thanks!

“My Wife Thinks I’m A Hero”
“Thanks for an excellent product. The installation is as easy as your website says it is. It took 1.5 hours from start to finish. If I had to do another, I could do it in about an hour. I used a dremel with a flexible extension and a cutting drill bit, not the cutting wheel. I drilled out the pattern first and then cut. The directions are well thought out and I wouldn’t change a thing.
I called a Jeep dealer a month ago; they gave me a price over $2k.
This is my wife’s car and she thinks I’m a hero for getting her heat because it’s getting cold in NJ now.
Thanks again.

“Ford Wanted To Charge Me $1600. No Way…”
“I ordered your product for my daughter’s F-150, followed the installation procedures and got the A/C working great. Ford wanted to charge me $1600, no way I was going to spend that money, all Ford had to do is design the system with an access panel to replace the blend door in case of a failure.
You have a great solution, it works great, it took me a couple of hours to finish, half of that time was spent removing that silly diverter vent, once that was out everything went very smooth………..It felt so great.
Thank you so much.”

“Your Directions Are Flawless”
Thank you for sending me the unit so fast. I successfully put it in my Jeep today. Your directions are flawless. They are easy to follow and very detailed, you really put a lot of thought into them. I found the pictures very helpful.
My neighbors came over and were very impressed with your product. They were also impressed with the way I was able to install it myself and save the money and hassle of having to have someone else do it.
If you ever need another testimonial I would love to give one for you.
You have created a great product. I can see someone making a business of installing your product for a lesser cost for those who are not mechanically inclined to do the installation themselves.
Thank you for all of your help. I truely appreciate it.
I can now keep warm because of you.
Thank you and happy holidays :)”

The following videos demonstrate the Heater Treater installation process for all Ford Expeditions, Ford F150′s and Lincoln Navigators. The video demonstration is performed on the F150, but the process is the same for Ford Expeditions.
Our apologies in advance. The videos are amateurish and probably too long. Feel free to skip through the boring sections. It will take about as long to do the fix as to watch the video.
Full instructions with pictures are included with the kit, so between the instructions and the video, the job should go fairly smoothly. From some of our customers comments, the hardest part is getting up the nerve to make the first cut into the box. Once you’ve made the commitment, the fix goes smoothly. If you ever have a reason to do a second repair, it will be very easy.
Failure of your heat and/or A/C in your Ford Expedition is due to the failure of your blend door.
