I know about the problem with the door locks completely failing, and using the IOD trick, or possibly reprogramming the BCM, but I don't think this is related. I can use the switch to unlock the doors and I hear the actuators working, but neither of the switches will lock the doors. I thought it may be a bad switch.. I replaced the driver side with with no results. Should I try replacing the passenger side, or is there something else I should be looking at?
