2002 dodge grand caravan manual door latch won't work

SOURCE: 2002 dodge grand caravan rear hatch latch

ok, then the lock actuator is most likely seized, if you need instructions to repair, let me know, you have to get the part first, this will be a dealer item most likely. Then it's pretty simple. Remove the interior panel on the liftgate, you will see the latch and lock assembly, and a rod coming from it,the rod leads to the actuator. remove the rod, the retaining screws for the actuator, the electrical connector and then reverse for installation. Any issues let me know.

Good luck.

sorry not sure the 12v prob will help this swtich works on 5v off 3v unlock 1v lock single wire lock/unlock logic signals
I found wiring diagrams at
http://www.dodge.com/bodybuilder/2004/docs/wd/rswd/tc.pdf
it is 2004 but use the wiring diagrams to test the wires
(most likely to fail where they flex)
because it is using logic gates disconnect the plug at each end of the wire you are testing or the damn thing will find a few diffrent ways to trick you.

2004-2005 CARAVANS HAD SOFTWARE ISSUE WITH THE BODY CONTROL MODULE THAT CAUSES THIS CONCERN..NEEDS A SOFTWARE UPDATE..CALL YOU LOCAL DEALER..TAKES ABOUT AN HOUR TO COMPLETE..AS FAR AS I KNOW THEY ARE THE ONLY ONES THAT CAN UPDATE SOFTWARE

You have to pull off the inner door panel and reattach the lock mechanism

Testimonial: "That did the trick-Thanks Brother!"
