2000 exped. with a boat load of issues

[nate47]

Just bought a 2000 expedition for a bargain. How ever its got tons of electrical issues. low beams aren't working (fuses are intact), nor the door locks, window is cutting in and out. The over head trip computer and compass are out. Blinkers are non existent but hazards work fine? This one has me stumped because the fuses are intact (i believe). could it be the flasher relay? Can not adjust the steering wheal, abs light is on. running board lights are and probably several other things that aren't working that I haven't noticed yet. Got my self in over my head on this one.

I did find 3 fuses blown, the cigarette lighter, and both right and left trailer stop and turn lamps. After pulling those fuses and checking some other ones the rig wont start now. Its turning over but wont fire up. I had pulled the fuel pump fuse when checking everything and replaced it right back. Dont know if I tripped something to cause it to not start?

There was a movie once called the Big Country But at least you could tell it was in the west. Do you think rather than listing America as your location as most of the expedition on this forum are in America This way we can get an idea if you may have problems due to being in the Salt belt area of America or the sun belt.

Also being you are having electrical issues it is nice to know which fuses you pulled by number or location That information can be found in your owners manual. Again having that information will save someone from guessing which fuses you pulled. And by knowing which fuse you pulled we can look up the diagrams for those circuits.

If you checked the fuses I hope you didn't just look at them and say they look good.
I hope you used a meter or a test light to test the fuses.

If you feel you may be over your head Then I will ask you How good are your troubleshooting skills, can you read and understand electrical diagrams. What kind of test equipment do you have.

Also would be helpful to know which model and engine you have 4x4 or 4x2. The more detailed information you can provide will help us on the forum help you.

Ok ok im sorry! lol Im in WA. Fuses 19(10A),20(10A), and 8(30A) in the power distribution box were clearly blown. fuse 3(20A)was clearly blown on the inside fuse panel. I have no tools until tomorrow so today I was just trying to get a jest of the situation. I have downloaded the owners manual already. As for my trouble shooting skills, poor when it comes to rigs with computers. All the rigs Im familiar with are pre 90s as I probably wouldn't have bought this rig if I realized the extent of the damage. Should have more info on what fuses are working tomorrow. Thank you for the speedy reply I figured might take up to a few days..

on a positive note, it will be a good learning experience.. its a 2000 expedition 4x4 triton 5.4

 

[Bedrck47]

Is it an Eddie Bauer which I am assuming it is

 

[Bedrck47]

I will look at the prints and see what all those 4 fuses control

its a XLT

 

[Bedrck47]

Thanks

There are two fuse blocks in the expy.

The Battery Junction Box (BJB) under the hood and the
Central Junction Bob (CJB) this is what they are called on the prints and also how I will refer to them

At this time we will not worry about fuse #19 and #20 in the BJB as they are for trailer towing

 

[Bedrck47]

fuse #8 BJB

 

[Bedrck47]

First thing I would like for you to check is the ground connections behind the kick panels drivers and passenger sides Make sure they are clean and tight

Check all fuses in both fuse blocks make sure they are good and post the results

 

[nate47]

works for me! I also checked to make sure the right fuses where in place. All was good except for audio fuse (#1 - 25a) in the CJB which had a 5a in it. tomorrow il have a multi meter and will be testing all the fuses and some relays. My plan of attack is to start the fuse/relays and work my way through the coils and then fuel if it goes that far... my major concern right now is why there are so many blown fuses and non working parts. Sounds like a short somewhere? I know these things have a lot of common issues such as the odometer flickering on and off (which mine is doing). I also plan to take that cluster off and re solder the bad connections.. So I guess my questions would be, if there is a common place where these rigs short out where should I check first?

 

[Bedrck47]

Check on you tube for videos on the inst cluster Pay attention on how to remove the main light switch be careful that you don't force the knob

Common problems are bad grounds Loosing a ground can cause all kinds of problems in the circuits

headlamp circuit

Look over the prints you will see which fuses are in the circuit

sent you a PM

 

[nate47]

well my multi meter finally showed up in the mail.. so I am posting my findings along with some other stuff... first things that caught my attention was the rust on this plate holding the CJB (pic #1) second thing was slightly corroded ground under the passenger kick panel (pic #2). Also in the passenger kick panel I found an exposed and corroded wire (pic #3) that leads to what looks to be a ground that is not grounded? (pic #4) This wire leads under an across the bottom front edge of the glove box and that is where I lost it. any clues as what it could be? as for my electrical readings I wrote them down as I went, please excuse my poor handwriting, I was cold, rushed and very hungry (pic 5 ohm readings) please note this is the CJB, I put my readings next to each fuse, E next to sites that are empty, on fuse #14 I got a negative 18 and on fuse #15 I got a negative 26, that cant be good right? also note that one relay 2 it is slightly chipped on the casing and was warm to the touch when all the others were cold, I haven't even had the key in the ignition for days.. so I went a head and pulled it. Found that the center prong was blackened and burnt.

 

[Bedrck47]

If you had the battery connected you should have been taking voltage readings on the fuses NOT OHM READINGS

 

[Bedrck47]

It is not uncommon to see some rust on the metal plate near the CJB it is unpainted and just from moisture over the years it will show some rust

Clean the grounds and make sure they are tight and connected to a clean surface Use some emery paper if needed

Most ground wires will be black although there are a few exceptions
