Ford F150, Ford Expedition, Lincoln Navigator installation information
The same plenum box is used on
these three models and the HeaterTreater kit will fix the blend door
problems on all three across the years noted in the listings. The
repair of the blend door in the plenum box is fairly straight forward,
but accessing the actuator motor on the bottom of the box is different
for different years and models. Note that Ford did not anticipate
the level of HVAC problems that are showing up on these models and NO
consideration was given to ease of access for repair. Standard
Ford procedures require complete removal of the plenum box to make a
repair. Our process is done without removal of the box, but there
will be some frustration and "physical persuasion" to get the system
accessible for repair. If you want to do it the "easy" way, take
it to the dealer and pay big bucks. If you are willing to put in
a little work, HeaterTreater is a proven and reliable fix.
The video below shows the process on a later model F150 and will give
you a good overview of the process and work involved. On the
F150, access is fairly easy. The one shown in the video has an
electronic module mounted below the plenum box, but earlier models may
or may not have this same module depending on year and option packages.
On the Navigator and Expedition, there is a center console between the
seats that has to be removed to get access to the plenum box. The
removal process is outlined below. Once you remove the console,
there is a plastic distribution vent below the plenum box that has to
be removed to get access to the actuator motor. Depending on year
and options, this vent may just distribute air to the passenger and
driver's side, or may have an extension to distribute air to the back
of the automobile. This vent is not a high pressure or structural
component and you will have to get a little "creative" to remove it.
If you loosen the metal struts on the front, it will give a
little more room to work. You can always just cut the vent down
the center with a dremel tool or hot knife to get it out. The
dash panels and center consoles vary across years with minor cosmetic
improvements, but the basic configuration and plenum box stays the
same. We don't have the staff or access to document every
different configuration, so there will be some times when you are "on
your own". Pictures below show what some of our cutomers have
done and will give you some clues.
VIDEOS
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.
The following pictures and center console removal will help with a Ford Expedition or Lincoln Navigator repair.
