Overdrive button changes nothing when pressed. Tested all the way up to 70 mph. I took apart the switch, cleaned all contacts, and have good continuity through the switch. I tried looking for a schematic but not even my trusty page of diagrams has one that points out the O/D switch so I can trace the prob unless I overlooked it. Any input is appreciated...
This is the schematic I was looking at but no luck.
