Just wanted to say that I had the same problem of intermittent ice and water dispenser and light. Checked continuity of white, white/red, purple, blue/black and dark blue wires. White and blue/black were not conducting through the harness and when I took the covering off, both were broken and so was the ground (green) wire. Fixed all three and put shrink on each and then the bundle. Thank you for posting this suggestion/fix.
