[Side note - I bought this car knowing that it would need work before it was road worthy - it's 28 years old and British. The price reflected the condition and I'm well satisfied with the deal.]
In any case, I removed the switch, and rather then replace it, I figured out how to disassemble it and made a successful repair. A new one would not have been that expensive, possibly twenty dollars. The biggest hassle would have been just ordering it and waiting for it to come in.
In a society where we routinely throw away the old and buy a new, it felt quite good to be able to make something work again. Sometimes satisfaction comes from wholly unexpected places.
Edit..... And I just noted that this was my "birthday" entry in LJ - It's the 313th since I started.
