Power door lock quit working on rear door

SOURCE: power windows

I think on that year there is a safety switch on the inside of rear door jam so the children cannot roll windows down and fall out. It should be on the back door when you open the door look for a caution sticker that says child protection switch, I sure hope thats the problem And if so Great If not get back to me I can look up where the power relay is for rear windows. Ok Take care, Bear001

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.

The switch itself may be faulty. Have you tested it with an ohmmeter? Have you tested power to the passenger switch with a voltmeter?

The lock actuator is probably broken in that door. We got one of the internet for 80$ and replaced it outselves and it solved this problem. IOD fuse is very temporary fix as system is sensing problem and flipping to protect itself like the breaker switches in the house.
