I need wiring color code for 97 Ford Expedition

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.

if nothing else was done to it and b4 the initial repairs it was starting fine, than it is obvios that you have mised some wires connection after putting the dash off and back on. there is all the main harnesses are located including the 1 to ECU and also wires that are going to the starter motor from your ignition lock. also you mite have an allarm or immoboliser that now have to be resset.. G/luck

UDER THE DASH BORD ON THE PASSINEGER SIDE

take the heatercore hoses off run water threw the core with a garden hose put the hoses back on there may be air in there good luck.

if the heater hoses are both hot its a blend door actuator, and possably the blend door its self, the way to make sure is to feel around under the dash . feel the black hvac box and if its feels warm then the heater core is good, you will have to remove the dash to replaced the bland door actuator and blend door ,i reccomend you replace both beacause its alot of work to remove the dash so make sure both components are replaced while you are in there

If you smell antifreeze it may be 3 possibilities: 1. you may have a leaking hose/hose connector , or water pump. 2. your heater core is bad and needs replaced. Unless you know what you are doing I would highly suggest taking to dealer for heater core replacement. The dash and steering colum has to be removed to get to the heater core. This is not an easy job believe me (about-900-1200 job). If you have your heater core replaced then also replace the climate control door. This is good preventative maintenance and also a a dollar saver. I would have a pressure check run on your radiator as a first thought. All you may have is a bad hose and that can easily be replaced.

to replace the heater core the dash board need to be take apart.

Dear Heater Core Hunter,
For your 01 expedition, that has the 5.4 liter motor in it, the heater core is located in the evaporator case assembly, where the blowermotor itself is located,This is a pretty darn good labor intensive job, if you open the passenger front door and get down onyour knees and look up underneath the dash.....that's what you're going to be removing and replacing, the heater core is inside of this black case.Please get back to me if you have any more questions...I'M HERE TO HELP!!!

With all due honesty, this is an extremely difficult operation and if you've not done one on a Ford vehicle before you would be best served to call in a proffessional. This is not to demean your talents but to save you a few thousand hairs.I've done hundreds of these and I still hate to tackle the job. In answer to your question, yes the dash has to be "softened" this is achieved by unbolting the understructure of the dash from the body sides. That, believe me is just the begining. There are numerous electrical, mechanical, vacuum and other connections to remove. Thanks, Dana

the heater core is located under the dash board on the passenger side. its a pain. here's more details
