You will need to have the body control module scanned to see if there is codes stored. The module is most likely faulty.

Sorry for the delay. I am having internet issues and will need to opt out so another Expert can help you with more information. My internet will be down all day tomorrow.

We have seen numerous issues with wires breaking in the drivers door jamb inside the rubber boot that covers the wiring that runs from the driver door to the body by the drivers door hinges. The door locks are controlled by the drivers door module which is located inside the drivers door. If a ground wire or power wire is breaking or shorting out against another wire, the door locks will not work, cycle up and down or also cause the remotes not to work.
