Maybe a broken cable
The needle on the speedometer of the 96 aspire is still moving, but it acts like it is out of control.
speed regulator sensor needs replacement
If the odometer has failed, does the speedometer still work? They are both driven by a cable which spins. If the speedometer is still working, than the odometer has jammed. Probably a dealer fix.
The gears in the speedometer are stripped. If the odometer is working then you have input.
The best way to find your vacume leak is to start it up and spray starting fluid around and when you hear the engine rev that's where the leak is at
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.
the abs sensor located in the rear end housing
Maybe the battery ran out.
You need to have it checked for codes to know what to diagnose.
check if the back of the spedomoter is pluged in th the gauge if not plug in
The speedometer is electronic on a 1999 Ram, and does not have a cable.
you need to replace the gauges
Because you didnt keep good care of it
