Driver door lock doesn t work

SOURCE: Power Door Lock Problem

The last post by maddog1321 was exactly what I had with my right rear door. The electric locks would not lock and unlock, and you almost couldn't do it manually without my feeling I was about to break something. I took the door panel off, oiled everything and got no relief. Finally, I saw the above post and drilled out the aft-most pop-rivet. THE WINDOW WORKED PERFECTLY! I didn't drill out the forward (closest to the handle) pop-rivet because I wanted to do one at a time so the solenoid would not fall out of place. I then put a new pop-rivet in place of the one I drilled out. I then reinstalled everything and the locks work like new.

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.

Check the locking solenoid / actuator in the door behind the panel, could be burned out or loose wire. It should take about 20-30 minutes to open, fix it and close the door panel if there's no major problem. Autozone might be able to help out with a solenoid.

if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
blue/red
blue/black
that go to door locks
