Speedometer and odometer dont work on ford f-250 1992 7.5 lt 2 wheel drive

Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the body control module (BCM). The engine control module (ECM) calculates the vehicle speed based on the controller area network (CAN) serial data message indicating the wheel reference speed from the electronic brake control module (EBCM). The ECM sends a CAN serial data message to the BCM indicating the vehicle speed. The BCM sends a class 2 message to the IPC indicating the vehicle speed.
The speedometer defaults to 0 km/h (0 mph) when any of the following occur:
• The EBCM detects a malfunction in the vehicle speed sensor circuit.
• The ECM detects a loss of CAN communications with the EBCM.
• The BCM detects a loss of CAN communications with the ECM.
• The IPC detects a loss of class 2 communications with the BCM.

Having the vehicle scanned for codes would probably point you in a correct diagnostic direction .

If the speedometer is still working, but the odometer does not, most likely the cable is broken (separate drives for odometer and speedometer within a single cable) or the dash unit needs replacing...

The odometer has nylon gears. I guess your gears could have stripped out. You can find a cluster with similar miles to yours and put that in. You can try replacing the wheel but if the gears in the drive part are busted, they won't drive a new wheel. If the gears on the odometer are busted then it won't work at all.

You have a broken odometer gear wheel which is very delicate and hard to change it cost less than fifty bucks but it will take a volvo expert one hour or more to change if your not volvo acquinted dont attempt to fix it.you will mess the dash board

Dear Sir/Madam, The problem is electrical. The speedometer/odometer box needs to be removed from behind the steering wheel (or after removing the steering wheel)...The bulbfuses behind the panel need to be changed and new electrical connections made for the speedometer/odometer to work.
Thanks, Netpreneur

Could be a ciggerette lighter fuse, usually cause this when it blows.

the speedometer/odometer works on a cable that goes into the side of the transmission with one 10mm bolt holding it in. It sounds as if the cable has been broken,pulled loose, or siezed up. Its easy to check the end under the vehicle but its very complicated checking it inside the dashboard. If you are a do it yourself type of person, id look underneath and see if the connection under the vehicle is still connected. Look on left rear of the transmission for a cable that goes into it and is held with a "Y" bracket and a small bolt.The dashboard part is the type of job where u got to make sure you remember where each screw goes to get back together.

My nephew has a 96 taurus also when his radio went out he noticed that his speedometer was not working as well so we check the fuses under the dashboard and found that a fuse from the radio memory was blown . We replaced it and the radio and speedometer and the odometer worked fine
