It has been reported that an issue exists that will cause the door locks to cycle when driving and/or become inoperative from the door lock switches. When the condition is present the door locks are inoperative from the switches, however they work normally with the key fobs. (If equipped with Remote keyless Entry)
It is recommended that you connect the Tech-2 to the vehicle and look at the door lock switch status (RFA data-list) it should be reading "Idle". If it reads lock or unlock then check for a possible sticking door lock switch and replace as necessary. also check the master power window switch for corrosion at the connector,seen some with this problem
