Just bought a 08 Silverado and the door locks don’t work. The lock button on both door’s do nothing neither does the power mirror buttons. All the windows work except for the passenger window unless using the button on the passenger door. The fob will sometimes unlock the passenger door but very weak if it does. I replaced the battery cause it was bad but didn’t change anything. Can hear a clicking in the fusebox when trying to unlock. Curious if anyone had any pointers before I start replacing stuff. Tia
