There can be a number of different reasons why speedometer or instrument clusters go out. The first step to figuring out the problem is ofter to determine if your speedometer gets it’s speed signal from an electric sensor (electronic speedometer) or from a cable (manual speedometer). It’s easiest to tell by pulling out your instrument panel and having a look at the back side. If all you see is an electrical plug then you have an electronic speedo cluster, if you have a mechanical cable of course it’s a manual unit.
Manual instrument clusters often fail when the cable itself wears out from the constant use over tens of thousands of miles. We don’t repair those here at Dr. Speedometer.com but we can get you a whole replacement unit for usually a great price. Electronic speedometer clusters actually rarely fail except for a few makes and models such as 2003-2006 GM vehicles which we specialize in. Those models almost always fail due to a faulty stepper motor that controls the gauge’s movement including the oil pressure gauge, temp gauge, tachometer and others. On other models it is more common to have a damaged wire or a faulty speed sensor which you can usually find mounted on your transmission. Other common failures are dim lights or failed electronic odometer displays.
