The speedometer on my car works intermittently. When I accelerate and release I hear a loud clicking noise and my speedometer and rpm stop working. It will jump from different speeds dropping to zero. Is my speedometer on its way out or could it be something else?
If the speedometer and the tachometer both stop working when you hear the clicking, it’s more likely to be a bad electrical connection, possibly at the rear of the instrument cluster.
A faulty vehicle speed sensor (VSS), or a poor connection to it, could cause the speedometer to work intermittently, but not the tachometer.
Thank You!!
