Why does my dashdoared go out while driving

Hello, You likely have a loose connection, or a short that changes when you hit a bump. The wiring for the dashboard, steering column, and fuse panel should be checked. Also, there may be an issue with the wiring for the steering column, which disallows power to some components when the short occurs. If you have other questions, or need more information, let me know, otherwise, here is a list of certified shops in your area with the training to repair your vehicle: http://repairpal.com/dodge-within-10-miles-of-saint-charles-missouri-63301
