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.
Remove the relay or fuse for the door locks.
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.
bcm is the body control module, it controls power locks,doors and other electronic accessories inside vehicle. cheers!!!!
All fuses are under the hood, next to the battery.
The dealer can turn it off with a scan tool.

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.
First check for a blown fuse. Check to see if there is power at the motor. If there is power at the motor then the motor itself is bad.
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
The 2005 Dodge Caravans have software problem in the BCM that causes the power locks to quit working. The only fix is to bring the van to a dealer for a software flash update.I disconnected the battery cable and pulled the BCM fuse and the system reset and the door locks are working fine again.I also got my power door locks working. I pulled and reinstalled (but did not replace) all fuses and fuse blocks (but not the relays). The locks started working after that.I'm not sure if I'm using this site correctly as I'm new, but I found that disconnecting and reconnecting the lamp and horn relays fixed my same issue with the locks.Several people suggested resetting the fuses under the hood, and it worked. Others tried unplugging and plugging back in the battery and that also worked for them.I tried the suggestions and it worked for a short time, but now the locks are not working again. Funny thing is that the rear hatch locks still work, but all passenger and driver locks do not. Time to take it in and have a pro fix them? Resetting the fuses and relays doesn't help anymore.
This depends a lot on the model year. The 2005 model in particular seems to have a lot of problems associated with power door locks and various other issues. For more information, consider visiting http://www.dodgeproblems.com/Caravan/
