Did you ever manage to find the solution? I'm in the same boat as you and really sick of trying to trace this issue. My Switch Pack is good to go and so is the fuse. So it's something between the fuse and the connector...
As far as I know it is the switch pack in my case. I never found anything between the fuse and light. The wiring diagram didn't show anything, if I recall correctly, and I was not about to pull the front clam to investigate.
The fix I outlined works great and takes no time to perform. Good luck.
