You need to replace the electric door lock solenoid.The electrical part of the solenoid may be compromised and is not letting the solenoid arm retract or extend to lock/unlock your door.

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

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.

Remove the door panel and reconnect the plug going to the front driver door lock or, if you can hear the motor trying to engage the door lock cam when you press the lock/unlock remotereconnect the door lock lever bar

Got it fixed. Swapped driver door switch with passenger and found that driver switch was bad and part of the issue. But doors still wouldn't unlock with fob. Don't remember if I read it here or on another site, but read that key fob buttons wear out easily. For $3.99 on amazon I figured I would give it a try. I ordered new soft button piece for key fob and everything works perfect. Thanks for all the suggestions.
I swapped driver side lock button with passenger button and found that it was the switch. But fob still wouldn't unlock doors. I am not sure on which site I read it, but they said that the buttons on key fob wear out easily. Bought the soft button replacemet on amazon for $ 3.99 and everything works fine. Thanks for all the suggestions.
