Hi, The fuse that supplies power to the door locks is located under the hood, just above the battery. This same fuse box also has a bunch of relays that control other functions of the van. The same fuse that supplies power to the door locks also supplies power to the lighter socket. I believe this is "big fuse" and is number 7. There should be a label on the inside of the fuse box cover that tell you what fuse it is. If the lighter socket is working, you could have another type of problem, as the door locks are control by the Body Control Module (BCM). I have included a link to a picture and diagram of the fuse box. Good Luck, Greg
If you happen to own a manual of the Wiring Diagrams, or can find one, page twenty-one will show the fuse system for the power locks. It lists D Lock Fuse 10A as connected to the Door Lock Control Module.
Pull the fuse
Door locks are protected by circuit breakers. A surge of power to a fuse would cause it to blow. They are located in the fuse panel.
There is not a specifically designated fuse for the power locks on the underdash fusebox label. The power locks are actually on the sunroof fuse (#15), whether or not the car has a sunroof. Check that fuse and replace if necessary.
Remove the power locks and windows fuse you will loose power for your windows also
Check the fuse and relay.

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 door locks are actually controlled by by the Body Control Module (BCM), but there is a main fuse where they get power from. That fuse is under the hood, and I have attached a link that shows the location and function of each of the fuses. Good Luck, Greg
What fuse in the fuse box is for the automatic door locks in an Infinity J30?
The 1997 Jeep Grand Cherokee power door lock fuse can be found in the fuse box. The fuse will be in the first column, third from the bottom.
