all the neddles in dash jumping back and forth..lost spedometer altogether
First guess is a malfunctioning Vehicle Speed Sensor on the transmission which sends the electrical impulses to your speedometer and odometer, or a short in a wire from the VSS to speedometer
My 2003 Windstar does the exact same thing. If I bang the dashboard it usually fixes it so I'm assuming the problem is in the cluster itself.
Debbie..... did you get this problem resolved? The common cause of this problem is the main cable connecting to the printed board inside the head assembly (where the guages are) has a broken solder connection (usually the ground connection solder failed, from age and it loses then gets then loses ground connection). You need to remove the entire guage head assembly (Takes time, but not extremely difficult). There are several video on Youtube.
