2002 dodge 3500 dullie, speedometer will go off and will come back on sometimes when driving. Is it the speedometer or part of the speedometer, such as a heat sink?
With key on after a while the speedometer will come back on, first the belt chime will ring then speed part will quit and sometimes the tach as well. Chime will ring again then all instrumenation will go dead.
there is a sensor on transmission that is causing this problem.
it works your speedometer cant remember what its called.
I pretty sure its a proximity switch it does speed and temp of transmission ect.
