Hello,

This could be a problem with your vehicle's Generic Electronic Module[GEM]. The GEM is responsible for your power locks along with instrument cluster warning chimes, power windows, courtesy lighting, Daytime Running Lamps[DRL], front washer/wipers, rear heated window, and delayed accessories. In the diagrams down below I have included the instructions for the removal and installation of the GEM, along with the Power Door Lock wiring diagram. Please go through this guide and get back to us with how everything turns out.

Thanks,
Alex

Just to add a thought. What about a miss adjusted door switch or some other input causing lock/unlock signal.
