Tail Light Diagnosis - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm trying to figure out my taillight/brake light problem, assuming I can describe it correctly:

Tails on: both sides work
Brakes on: Left side on, Right side off
Right Turn and Brakes on: works correctly
Left Turn and Brakes on: works correctly

Seems that if a wire was crossed, everything would still function, just burn on the wrong filament. I've spent days trying to figure out why I had a brake light sometimes and other times I didn't, only to notice they worked with the left turn/brake light combo...

Ideas?
