I have a 2015 Terrain and the right headlight went out. I changed the bulb and turned on the lights and it still did not work. I checked the old bulb and it looked good. The connector is in good shape. I looked for the fuses and found I needed to change the bcm 30. It was good but switched with another 15a fuse but nothing. All wires look clean and I did not see any corrosion as much as I can see through the wheel well. Any ideas?
