Update: circuit boards, light and wiper switch were replaced.
Some where there is a hot feed to the dash lights.
The dimmer switch makes the bulbs blink, as they stay lit
Not into fuse block yet, (back to work in Norfolk, Va)
One last thought, I should shut the drivers door, and see if console lighting works off of new L switch.
Thoughts and schemes appreciated.
Big 70 birthday 🎂 today.
God bless all
