No, the red paint was me, as I am partial to red lights !
Much of the electrics were non functional when I had the car - glove box lamp & switch, "Trunk" lamp wireing,
Tail light wireing, windscreen washers, clock illumination........so I fixed it all last winter.
The Blower switch was in poor condition, bulb contacts corroded, ceramic broken, rheostat dirty,
I made a new backplate to fix the ceramic, but the bulb contacts & spring were corroded away, so I soldered wires to a new bulb and attached them to the connector block pins on the back of the switch - it all works fine now.
Keep well
Paul
