Ok I have a 2003 Caravan and I have just found out that my I O D fuse is causing all dash lights to light up and for me to lose all my gauges. Everyday my door locks unlock after a few minutes after they lock ( while driving). I need to understand why this is the problem. Plus my van acts like it is jerking while driving over 60 mph. Any help will do please. This is my first Dodge.
