Speedometer Wires fuses whatever I need to know about getting it fixed
SOURCE: speedometer wire
I have some good news and some bad news for you. The bad
news is that chances are real good that the speedometer cable is
broken. The good news is, it's not hard to replace.
The speedometer cable goes from the transmission directly to your
speedometer in the dash. Look at the firewall from the engine side and
you will see a black cable about a ½" thick coming out behind the
instrument cluster. That's the speedometer cable housing. Trace it down
to were it meets the transmission. There will be a large, screw on type
connector. With either the proper size wrench or a pair of pliers,
unscrew the fitting and remove it. Inside you will see a cable with a
square end. That is you will if it's not broken off. If you don't see
it, look into the fitting it screws into. You will see a square fitting
that the cable fits into. If the piece is in there, pull it out with a
pair of needle nose pliers. Chances are it won't be broken there.
Now sit in the car (I'm assuming your boyfriend has been doing the
dirty work so far) and watch the needle in the speedometer. Have him
turn the cable itself sharply in both directions and see if the needle
moves. If it doesn't, then you have a broken cable or a bad
speedometer. But I'd bet real money it's the cable. If he has a
reversible drill, he can chuck the end of the cable into it and run the
drill in both directions, that will tell for sure.
If it does move or show a speed, then you have a bad pinion gear
inside the transmission. The only way to fix that is to open up the
transmission and replace it.
Okay, to replace the cable follow it from the transmission to the
fire wall noting the route and undoing any holding attachments. When
you reach the firewall, it's time to move inside the car. The
instrument cluster has to come out. You can go to the library and look
up the procedure for that exact car. If you can, check out the book and
bring it home. If not, photocopy the page(s) and use that. Removing the
cluster is not that difficult to do.
Once you have it loose, push the cable through from the engine side
and guide the cluster out. There are generally 2 large plugs that plug
into it. Move out the cluster enough to reach the plugs and unplug
them. You have to be gentle, even though they are hard to unplug. Once
you have them unplugged, it's time to unhook the cable from the
speedometer. Some have a plastic latch you have to press to release it,
some are screw in and some are a push and twist.
Once you have it disconnected, pull the cable out from the engine
side and throw it away. To install the new cable, just reverse what you
just did. And that's it, you're done. Take it for a ride to make sure
it works and you're in business. Make sure when you put the new cable
in you do not kink it or run it near anything hot. Just route it the
same way it was and you'll be okay. One more thing, I would recommend
taking the old cable with you when you go get the new one, just so you
can match it up and be sure you're getting the correct one.
And Natalie, if all else fails, you can throw the stupid car away. ::Running for the door::

Your problem is NOT a fuse. The speedometer receives an electronic signal from an analogue transmitter mounted in the rear differential. It's the little button in the rear diff with two wires attached to it. Check to see if the wiring is chaffed or broken. If not, then it's probably the transmitter. A competent mechanic should be able to replace one for less than 200.00, parts and labor. If this does not fix it, then the problem is in the head, which can be expensive. You might get a used head if you can get a 90 day guarrantee on the part from the salvage company.
Good Luck!

the speedo could be the sensor on the gearbox the lights not working could be the bulbs have blown
SOURCE: 1999 ford explorer xls speedometer
doubt it is a fuse,could be,but i would check the speed sensor under the vehicle at the transmission,it will be a plug in with 2 or 3 wires going in to it,it will be on the side of the trans.towardthe rear of it.
SOURCE: speedometer not working fuses are fine
ok if its a cable driven speedo then the cable has snapped or the speedo drive that goes into the gearbox is gone ,,also if its electric speedo then id go with the electric speedo in the gearbox ,,,a ten mil nut holds it in and it goes straight down into the gearbox,,youl see it from under the bonnet ,,
