Hi-jcking a thread again, but one of the things that doesn't wprk on my '66 is the washer pump.
There is a plunger built into the wiper switch, but it doesn't appear to do anything. The washer motor appears to be fitted to the lower rear of the wipesr motoe (under the dash).
Is it supposed to be the pump up type? I might just bin it in favour of a electic one.
