broken speedometer

I found that leaving iginiton key off and holding in the trip mileage button until a self test come up and letting off after turning the van to accessories position fixed my problem.Thanks to the person who posted this info very helpful . b

Normally when a speedometer stops working, it's because the vehicle speed sensor has failed. This is the most common cause.

The second answer on this link is the correct answer. The ignition key was on when you were jump starting the van initially and it caused a surge of electricity. I had a similar problem with one of these about a year ago. http://answers.yahoo.com/question/index?qid=20070908184317AA58qIU
