I'm so proud. Tinkering skills I learned here lead me to take apart my stering collumn.
Old issue, fog light seemed shorted out. Lights would come on randomly.
Turned out to be a mechanical issue. a plastic pin had worn down so it could no longer raise the contact and break the circuit reliably.
I thought it was shorted for years. Anyway, I used some JB weld to build the pin back up and it works good as new.
Thanks BYOAC!
