sounds like you have a wiring problem in the main lock switch in the driver side door or wires that run from there to the other doors. one of the wires in this system does not have a good enough connection to allow enough current to operate the locks. put another way, the wire itself is introducing unwanted resistance which reduces the current flow. the resistance could be a result of a poor connection at a junction or a section of wire which has corrosion or some other problem which diminishes flow. to find exactly where the problem lies will involve removing door inner panels and making voltage drop tests across connections. works something like this: i started out with 12v dc, i know this component should use 3.4 v (or whatever it is) but now i only have 4 v coming to this next component. so the wire is using some of the voltage. some drop in the wire is normal, but not very much. that is how i would troubleshoot it. you can just check the connections to power and ground, just look at things and make sure you don't see corrosion, wiggle connections and see if it makes something different happen, but you will still have to take the doors apart to do it. hope that helps

you have to replace door lock completely , there is small plastic gear on electric motor which moves locking mechanism and seems that gear is broken, but it is not available as separate part.
