Ok here goes. I own a 2003 Silverado 2500HD with the towing package. I am having a trailer brake light problem with the right brake light. I have tested at the plug and fuse box and have no power. Other than replacing the harness is there anything else I should check? The fuse box under the hood doesn't list any fuses for the trailer brake lights. The fuse box by the drivers door has the fuses for the trailer brake lights and I have tested for power there. Left brake light on trailer works fine. Thanks for your input.
