I had to drive 50 miles just to find the mini J fuses for my trailer lights and none that I could tell besides just the socket itself had some condensation on it.
Dealerships replacing the harness but they are not sure when it's going to be in. From what I can understand is they are back ordered from gm. Have a feeling a recall soon if that's the case.
Have a 2015 Silverado and one of my right rear taillight sockets already corroded to the point that it doesn't work. Looks like the wheel well liners don't cover enough to keep water and dirt off the housing. Anyone else have this issue?
