i am having the same problem. it's with my drivers side door. about 2 months ago I replaced my door's lock actuator because the motor was getting weak and it stopped locking the door. Now im thinking this new actuator (OEM) has failed. I am not sure if the GM5 module could be causing this.. I don't think so. if the dash indicator says door is open and the window won't go up all the way, then the sensor in the door lock actuator has failed and there is nothing you can do to repair it since its a sealed unit. Any thoughts?
