Unplug Battery for 10 minutes. BCM issue. Not sure on original cause.
It is normally due to a software bug in the bcm. The dealer can flash New software into the bcm to correct the problem.
The power door locks on a Dodge Caravan can stop working if the fuse is bad. Check the power door lock relay fuse that is located in the engine compartment on most Dodge Caravans. It should be next to the battery.
check the door lock master switch usually that is the problem
Remove the relay or fuse for the door locks.
The IOD fuse is on the left side of the fuse box under the hood, is a 15 AMP fuse. Without or blowed fuse, the radio would not work, power locks does not work, accessories light would not work. This information is for a 1999 Dodge Grand Caravan.
bcm is the body control module, it controls power locks,doors and other electronic accessories inside vehicle. cheers!!!!
The dealer can turn it off with a scan tool.

All fuses are under the hood, next to the battery.
The fuse for the door locks in a 2002 Dodge Caravan is located in the fuse box, which is typically found under the dashboard on the driver's side. You can identify the specific fuse by referring to the diagram on the fuse box cover or the owner's manual, where it will be labeled for the power door locks. If the fuse is blown, replacing it should restore functionality to the door locks.
What you probably need to do is to check you battery because i have a dodge 2004 also and my locks did the same thing so i just replaced my battery and the locks started working again.
you have your wires routed wrong
take the van to the dealer and have the body computer up dated the easiest way to see if this will work is to unhook the battery and if the locks go back to working it will fix it
