I don't believe so.
I beleive your van requires a DRB III scan tool in order to change/program such things (my 2000 intrepid does). This is a dealer only item (chrysler proprietary). You can purchase one, but last time I checked they ran around6,000! :wow: And that doesn't include the programming updates, you have to be an authorized dealer to get those (or you have to have a buddy set you up under the table)
Also, you can really mess up the vehicle if you're not sure what you're looking at.
Here's a couple links:
