I had the same problem and resolved it by disconnecting the positive battery cable for 1 minute and then reconnected it and the computer had reset itself and problem was solved. Never did determine what caused the problem to occur in the first place but it fixed the problem nontheless. Good Luck and let me know if it works for you as well. Bye for Now
Need to know which light is blinking.
AutoAnything. The AutoAnything website has an extensive selection of lights for a Dodge Caravan. All of the lights for sale have reviews. If you want to find reviews on the "Caravan of Light" album by various artists, check Amazon.
Change your fuel pump unit(its in the tank).
The headlights on a Dodge Caravan are adjusted by turning the screws located on the top and side of each light. They should be adjusted with the lights pointed at a wall for accuracy.
if there is a little round red light blinking on dash right side it is your key
check fuses, check brake light switch behind brake pedal.
you need a scanner.there's many cheap "[obd2] scanners out there. or you can go to autozone and they scan it for free.
Decorative blinking lights work in a series. As long as the series is completed and a blinking specific light is in place you have a beautiful display of blinking decorative lights.
Fuse or brake light switch are most likely.
Water is commonly getting into the hazard light systems
