Heater core replacement.

go on youtube you are better off going there for an answer than waiting on here , good luck ,

Lonnie. This is a hard job but heres your answer. I have done this twice myself but it was for heater core replacement the blend door is connected to the heater core assembly. Go to youtube and search "ford expedition heater core replacement". This video is outstanding the guy who made it points to all the hidden screws and bolts. It is an all day job just getting to the heater core. You have to drop the steering column and take off the whole dash to get to the door. both times i did this it took me 2 days. One day to disassemble and the next day to assemble. If you take to dealer be prepared to spend between 900-1200 dollars. The climate door only cost about 20 bucks. God bless you and keep me posted.

This differs greatly from car to car, some simple, while others require removing the entire dash unit. Simple answer is check a parts store shop manual to see which type yours is.

go to cherokeeforum.com join and post there there is a guy with a writeup and pictures his screenname is ol;blue but to answer the question the dash needs to come out it took me about 7 or 8 hours over the course of 2 nites dont forget to replace the heater core as you dont want to do this twice look for parts at rockauto or partsgeek

Heater core is under the dash, the dash will have to be remove to replace the heater core, you will also need to have the a/c system recover, evac, and recharge if the system has freon, when this repair is done, this is about a 10 hrs. job.

This depends on how hard it is to get to your particular vehicle style core. Some vehicles require to rip out the entire dash, others may be exposed. For an exposed heater core, I've done it in about 30 minutes to an hour...for the dash destruction add in about another hour or 2.

It depends on how handy you are. Heater cores can be a b@#$# to replace, you have to take half the dash apart. That's why it's so expensive, it's labor, not parts.

On the other hand, an '04 shouldn't need a core already, that's something a 10 year old car needs. Get a second opinion.

This is a fairly easy fix.The steps are as follows:

1. Disconnect the heater hoses under the hood.
2. Go to passenger side under the dash remove the lower panel from the dash to access the heater box.
3. Unplug any and all connections on the lower half of the heater box and remove the lower half of the box should be about six screws you should see the heater core and the evaporator core.
4. Heater core skinnier of the two should have one or two straps holding it in remove the straps and remove the core and replace.

Have replaced my heater core in my 2001 regular cab 4wd in december 2009. Had to pull the complete dash including the complete metal dash behind the dash that you see. Also had to remove the right passenger side inner fender well to acess the remaining two bolts that hold the heater core cover to the firewall. Its an insane job to do but the repair shop books call for 9 1/2 hrs to do the job. I'm not an expert but this is what it takes.
