Opened up the turn indicator, partly to clean and partly to see how it works. I have read somewhere that it may be of the self-cancelling type, but although I don't quite understand the design, I can't see the spring in there being strong enough to do anything. The contact mover that moves with the handle to turn the indicators on and off is quite stiff, and I can't see the spring overcoming that, even when new. However, there is definitely something more to the design, what with the cam and adjuster screw on the backsideof the housing. Anyway, everything was cleaned and lubricated, and as a manual on/off type switch it should work well.
Will clean the panel itself closer to re-installment time. The green plastic outer lens of the turn indicator light is fractured, but I'm hoping glue and some polishing will help. The yellow pull on/off switch, for the dome light, has "Made in the USA" stamped on the inner box, and so I don't think it's a factory option; more likely installed by the dealer in Toronto. Also, the hole in the panel isn't as neat as that for the turn indicator and light.
