Hey everyone, I have a 2008 GMC 2500 Crew cab SLE with factory power locks and am having a real issue. One day all four stopped working at the same time. When you press the lock or unlock button, there is a noise under the dash, and the actuators also make noise in the doors, but it does not work. I have checked the fuses, nothing is wrong with them. I am hoping that it is not the BCM, Is there anything that I am missing or do I just need to get a new BCM, Thanks for all the help!
