1993 Ford F-150 Question: Speedometer not working



JPLaw, 5.8L V8, Powhatan, VA, December 28, 2009, 15:56

My 1993 Ford F150 4x4 speedometer began moving from 0-100 mph unexpectantly. I would keep going back anf forth for about 4 minutes and then it would work like it is supposed to. However, last week when I drove the truck, the speedometer did not work at all and the ABS warning light is lit on the dash. I also found out that my 4x4 does not work when I tried to get out of my driveway in the snow.
Any ideas as to the problem? Thanks.

    I would focus on the ABS issue, retrieve the diagnostic codes from the ABS Control Module and perform a diagnosis. The vehicle speed signal is often provided from the ABS System, so any issue with the ABS could cause this problem.
