When the heater fan switch on mine broke the closest I could find to replace it was from Holdens, code 020.034
Heater Fan 2-Speed Rocker Switch The only differences between it and my original were the icon and the fact the new one was illuminated.
Curiously, although none of my existing switches lights up, I found the loom had an unused spade connector which I plugged in and it worked! So now when the Morgan headlights are on the heater switch alone glows on the dashboard. I expect one day I will replace the other three switches with newer illuminated ones.
