Chrysler Voyager Speedo Reset Procedure 

If you have a Chrysler Voyager and the speedometer's not working,
this reset procedure should fix the problem.
An electrical spike from the alternator or other component can cause the speedo and the rev counter to stop working. Additionally, if the instrument needle is stuck below the stop pin instead of resting above it, then this procedure will check all the instruments and warning lights in the instrument panel and hopefully fix any problems.
