check the engine thermostat by mschmal

This is a 4 dollar part that when it fails it does so in a way to keep the car from overheating and the cabin heater core from ever getting hot enough to give you "heat"
 
If the air from the vents gets colder at highway speeds, then this is the likely culprate.

Hello:
 
I have a very similar problem as to these other postings I have read,I have a 1998 ford expedition xlt with a 4.6 ltr engine,any ways
I just realized that my heat is not blowing hot air it is blowing luke warm to cold air & I am freezing in the a.m.!! even when I start the truck in the am I let it run for like 20 min & still no heat!! I changed the thermostat and did a radiator flush with top of the line anti freeze,on the high way it does get worm thats about it,but when i slow down it gets cold again. I am starting to think the heater core is on its way out!!
 
does anybody have any idea why this is happening? is my heater core on the way out??
is it easy to change?what else can it be?
 
Thank You
 
I would like to fix asap as I do have kids to bring to school in the am!

Expedition Climate Control Problem by tammiep

Hi,
I have a 2004 Expedition. My air only blows up by the window, and not out the vents like it is supposed to. The switch that controls where the air will blow doesn't seem to be working properly, because I only get air flow at the window ( like defrost) and off. Do I need to replace this switch or is it some vacuum line or something that is not allowing the air to transfer to the proper location that I select?

I have a 05 Expedition EB with heated and cooled seats and had the same problem. I called the dealer and they said it was the control unit, but I did'nt think so because when I tried to switch it to vents I can hear a clicking noise like it's trying to move. So I started pulling the center console out and looking at the vacuum lines that control were th air gets switched. there is a manifold that has 6 tubes in it. A black,white,red,orange,blue, and yellow. The black and white are the two that come from the vacuum side so I took a air compressor and blew into all the tube and then it started working again. So I think the small tube must have had some junk in the line. I took some pictures of the area so if would like to receive them just email me at eddiemcninchatt.net and I will send them to you.

BRRRR COLD AIR IN FRONT HEATER 98 EXPEDITION by repoman3

Folks I am brand new to this forum and maybe I over looked the fix or maybe I didnt, anyways I have no heat in the front of my 98 ford expedition but plenty in the rear heater system. I understand that there is a blend door actuator that controls the Max cold-maxheat, but where is the damn thing and what do you do to fix this reoccuring problem that the Ford recall team seems to ignore?

seams to me we have the same problems with these ford expeditions, I have a 2003 xlt ,overhead rear heat works great, dash heat stay`s cold no matter where you set the temp control knob. any suggestions, my local ford dealer charged 77 dollars just to tell me it needs a blend door controler, and it will cost me 1300 dollars to fix , forget that i`ll trade it off first, anyone know what i can do to fix it myself, ?
