the little gear that turns the numbers is broke and the only way to fix is replace the whole speedometer.
If the abs light is on, then you might have a rear axle speed sensor issue. If not, then you have a cluster problem.
I have the same problem replaced speedometer clurstor got one out of wrecking took awhile to find one that worked ps you chang the sensor on the transimission . hopes this hepls
i just changed the speed sensor on my 91 and it took care of that same problem.
This happend on one of my cares. It was just a cable that needed to be changed under the hood. I am sure anyone at napa or autozone can help you out.
i have a 91s10 4.3 auto and mine is not working either im going to change the vehicle speed sensor on trans and see if that works
needle might be cracked
You can't, because it is illegal. well that isn't entirly true you can but you wont have a speedometer either.thats all I have to say.
its a pickup truck 1999 f250
I am not sure if the 1999 is a magnetic pickup but my 2000 or late 1999 uses a magnetic pickup that screws into the side of the transmission. It has a wire plug that unplugs from it and they you can unscrew it from the side of the transmission. When my speedometer quit working it also cause the transmission not to shift correctly. I unscrewed the magnetic pickup and it was covered with iron filing which I removed with a clean cloth. When I screwed the old pickup back in the transmission I made sure it was not in far enough to rub on the gear teeth that rotate by it. The speedometer and the transmission worked fine after removing the iron filings from the end of the pickup.
Someone knocked a wire loose.
The exact location of the speedometer cable is dependent upon the make and model of your 1994 pickup truck. In general, the speedometer cable goes from the speedometer to the speed sensor.
There is no speedometer cable on that vehicle. The speedometer is driven electronically.
