First check the fuse for the 2003 Cavalier gauge. Next check the fuel sending unit in the fuel tank to insure that its working properly. Check the gauge next, then the wiring for the system. One of these units is causing your gauge to not work.
A blown fuse can cause your fuel gauge and speedometer to stop working. Replace the fuse. The fuse can be found in the fuse box. The location of the fuse will be listed on the inside cover of the fuse box.
why would a speedometer stop working on a Mazda
=A Gage is gun a 12 gage=
The gauge has failed.
You may have a blown fuse.
The problem would be that the car is messed up
If the digital dash lights up but shows no numbers for the speedometer on a 1989 Thunderbird LX, it is possible that a fuse is blown for the speedometer and the fuel gauge. There is more than one light in the dash for the speedometer.
If it is the gauge you have to pull the gauge cluster. If it is the cable you have to get under the car and replace it. It will be the only cable on the tranny. Good luck
The gauge is part of the instument cluster ( the part with the speedometer ).The gauge is part of the instument cluster ( the part with the speedometer ).
Probably a fuse. They are all linked together.
A speedometer will stop working if the gauge has failed, the wiring is loose, or the sending unit has become defective. Each component must be tested to determine the cause.
The VSS (vehicle speed sensor) may be at fault.
