A 2012 35K having issues with lighting on the Porch and one side of stairwell light. I have changed bulbs and checked switch and looked at wiring to all that is visible. Have there been issues with wiring breaks or factory splicing that might help me zero in on this problem. The switch works and the porch light used to work. Do the switches stop working? The stairwell lights on the one next to the cabinet but the porch and the stairwell light near the door henge side is not working with the switch. Help!
