Hey all, I just had a warning about my rear brake light. I replaced the bulbs, which were out, and started the car. Upon checking the lights, now the upper most brake bulb (middle of unit) and rear side marker is out. Ive cycled the bulbs proving they all work. I tried a new lighting unit, plugged in the lights and the same upper portion was out. I also just changed out the connector and wiring that plugs into the bulb, no cigar.

I had the corroded and melted plug on the other side which is why i changed out and trouble shot the harness, wiring, and plug. This is turning out to be a little bit more it seems. Plus i could see the damage on the other side, this one looks fine, and when in the working sockets all the lights work... any suggestions?
