Remove the relay or fuse for the door locks.
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.
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.
It controls most of the interior electronics such as lights, wipers, locks, theft alarm, etc.
The relay for the locks is usually located in the fuse panel (usually lower left of the steering wheel) and is one of the larger rectangular boxes plugged into the fuse panel.
