2001 Dodge Van 6 cyl Two Wheel Drive Automatic

After a jump start the speedometer needle went all the way around and against the pin where is now stuck. When the van is running the needle wants to go, but the pin prevent it from doing so.
How can I fix it? Thank you, Bruce

Three ways to fix the naughty needle. This is not a spring-loaded needle like they had for decades. It is a pointer attached to a "stepper" motor. This type of motor has four coils of wire that are pulsed alternately by the instrument cluster computer to set the pointer to the desired position. The magnetic fields cause the pointer to try to go to its desired position by the shortest route which in this case, is toward the stop peg.

The easiest way to reset the needle is to just drive at higher than half the maximum reading on the speedometer. If it reads "120 mph", drive more than 60 mph. At that point, the shortest way for the needle to get to 60 is to go down. From there, it will continue to respond like normal.

The second way is to connect the Chrysler DRB3 hand-held computer and select "Actuator Tests" under "Instrument Cluster". The scanner will run all the gauges to 1/4, 1/2, 3/4, and max, then back to the lowest values. The speedometer pointer will follow the commands back to "0".

The third way just involves removing the bezel and physically pushing the needle back down.
