I have a 97 Chevy c1500 ext cab. I bought a new led high mount brake light. It works when I push the brakes but the cargo lights aren't working. When I check with a light the bulb barely lights up and when I'm checking it my door lights and lights under my dash come on. I've replaced all my fuses in the engine compartment and in the fuse panel when you open driver side door. Wondering if it might be a relay or if there is damage to that wire along the way. I'm no electrician so all help is greatly appreciated. Here are pics when I'm testing the cargo light and brake light.
